NAME

Net::LDAPapi - Perl5 Module Supporting LDAP API

SYNOPSIS

use Net::LDAPapi;

See individual items and Example Programs for Usage

DESCRIPTION

This module allows Perl programmers to access and manipulate an LDAP
based Directory.

Versions beginning with 1.40 support both the original "C API" and
new "Perl OO" style interface methods.  With version 1.42, I've added
named arguments.

THE INTIAL CONNECTION

All connections to the LDAP server are started by creating a new
"blessed object" in the Net::LDAPapi class.  This can be done quite
easily by the following type of statement.

$ld = new Net::LDAPapi($hostname);

Where $hostname is the name of your LDAP server.  If you are not using
the standard LDAP port (389), you will also need to supply the
portnumber.

$ld = new Net::LDAPapi($hostname, 15555);

The new method can also be called with named arguments.

$ld = new Net::LDAPapi(-host=>$hostname, -port=>15389);

Instead of the above mentioned argumens -url can be used in the
following form

$ld = new Net::LDAPapi(-url=>"ldap://host:port");

Setting -debug=>"TRUE" will enable more verbose error messages.

Note that with named arguments, the order of the arguments is
insignificant.

CONTROLS

In LDAP v3 controls are an additional piece of data, which can be
submitted with most of the requests to the server and returned back
attached to the result.  Controls, passed to the call, are separated
in two types.  The client side controls, which are not passed to the
server and are of not much use.  They are denoted by -cctrls named
parameter.  The server side controls, denoted by -sctrls named
parameter are actually passed to the server and may affect its
operation or returned results.  Each entry of the result may have
controls attached to it as well ( see parse_entry(...) call ).

-cctrls and -sctrls must be reference to array of controls.

To create control call create_control(...) method. Bellow is an
example of creating valsort control.

my $asn = Convert::ASN1->new;
$asn->prepare('SEQUENCE { b BOOLEAN }');
my $berval = $asn->encode(b=>1); # or 1

my $ctrl =
  $ld->create_control(-oid=>Net::LDAPapi::LDAP_CONTROL_VALSORT,
                      -berval=>$berval,
                      -critical=>Net::LDAPapi::CRITICAL);

The control is to be freed by calling free_control($ctrl).

If contol is attached to results entry, it can be retrieved by
calling parse_result($entry). If no entry is passed to
parse_result(...) then current entry is used. It returns hash
with following keys

Key           Value
-------------------
matcheddn     string
errmsg        string
referrals     array reference
serverctrls   array reference

You can look into content of the control by using get_contol_XXX
functions like this:

local %parsed = $ld->parse_result($entry);
local $serverctrls = $parsed{"serverctrls"};
local @sctrls = @$serverctrls;
if( scalar(@sctrls) > 0 ) {
  foreach $ctrl (@sctrls) {
    print "\nreceived control\n";
    print "oid = ".$ld->get_control_oid($ctrl)."\n";
    print "berval = ".$ld->get_control_berval($ctrl)."\n";
    print "critical = ".$ld->get_control_critical($ctrl)."\n";
  }
}

BINDING

After creating a connection to the LDAP server, you may need to
bind to the server prior to performing any LDAP related functions.
This can be done with the 'bind' methods.

An anonymous bind can be performed without arguments:

$status = $ld->bind_s;

A simple bind can be performed by specifying the DN and PASSWORD of
the user you are authenticating as:

$status = $ld->bind_s($dn, $password);

Note that if $password above was "", you would be doing a reference
bind, which would return success even if the password in the
directory was non-null.  Thus if you were using the bind to check a
password entered with one in the directory, you should first check
to see if $password was NULL.

To perform SASL bind fill in appropriate parameters calling
sasl_params(...) and call

$status = $ld->bind_s(-type=>LDAP_AUTH_SASL)

Bellow is an example of GSSAPI K5 bind parameters.

$ld->sasl_parms(-mech=>"GSSAPI", -realm=>"domain.name.com",
                -authzid=>"",    -secprops=>"",
                -flags=>LDAP_SASL_QUIET);

For all of the above operations, you could compare $status to
LDAP_SUCCESS to see if the operation was successful.

Additionally, you could use 'bind' rather than 'bind_s' if you wanted
to use the Asynchronous LDAP routines.  The asynchronous routines
would return a MSGID rather than a status.  To find the status of an
Asynchronous bind, you would need to first obtain the result with a
call to $ld->result.  See the entry for result later in the man page,
as well as the 'ldapwalk.pl' example for further information on
obtaining results from Asynchronous operations.

The bind operations can also accept named arguments.

$status = $ld->bind_s(-dn=>$dn,
                      -password=>$password,
                      -type=>LDAP_AUTH_SIMPLE);

As with all other commands that support named arguments, the order of
the arguments makes no difference.

GENERATING AN ADD/MODIFY HASH

For the add and modify routines you will need to generate
a list of attributes and values.

You will do this by creating a HASH table.  Each attribute in the
hash contains associated values.  These values can be one of three
things.

  - SCALAR VALUE    (ex. "Clayton Donley")
  - ARRAY REFERENCE (ex. ["Clayton Donley","Clay Donley"])
  - HASH REFERENCE  (ex. {"r",["Clayton Donley"]}
       note:  the value inside the HASH REFERENCE must currently
           be an ARRAY REFERENCE.

The key inside the HASH REFERENCE must be one of the following for a
modify operation:
  - "a" for LDAP_MOD_ADD (Add these values to the attribute)
  - "r" for LDAP_MOD_REPLACE (Replace these values in the attribute)
  - "d" for LDAP_MOD_DELETE (Delete these values from the attribute)

Additionally, in add and modify operations, you may specify "b" if the
attributes you are adding are BINARY (ex. "rb" to replace binary).

Currently, it is only possible to do one operation per add/modify
operation, meaning you can't do something like:

   {"d",["Clayton"],"a",["Clay"]}   <-- WRONG!

Using any combination of the above value types, you can do things like:

%ldap_modifications = (
   "cn", "Clayton Donley",                    # Replace 'cn' values
   "givenname", ["Clayton","Clay"],           # Replace 'givenname' values
   "mail", {"a",["donley\@cig.mcel.mot.com"],  #Add 'mail' values
   "jpegphoto", {"rb",[$jpegphotodata]},      # Replace Binary jpegPhoto
);

Then remember to call the add or modify operations with a REFERENCE to
this HASH.  Something like:

$ld->modify_s($modify_dn,\%ldap_modifications);

GETTING/SETTING LDAP INTERNAL VALUES

The following methods exist to obtain internal values within a
Net::LDAPapi object:

o errno - The last error-number returned by the LDAP library for this
  connection.
        ex:  print "Error Number: " . $ld->errno . "\n";

o errstring - The string equivalent of 'errno'.
        ex:  print "Error: " . $ld->errstring . "\n";

o ld - Reference to the actual internal LDAP structure.  Only useful if
  you needed to obtain this pointer for use in non-OO routines.
        ex:  $ldptr = $ld->ld;

o entry - Reference to the current entry.  Not typically needed, but method
  supplied, just in case.
        ex:  $entry = $ld->entry;

o msgid - Get msgid from an LDAP Result.
        ex:  $msgid = $ld->msgid;  #  msgid of current result
        ex:  $msgid = $ld->msgid($result) # msgid of $result

o msgtype - Get msgtype from an LDAP Result.
    ex:  $msgtype = $ld->msgtype;  # msgtype of current result
        ex:  $msgtype = $ld->msgtype($result) # msgtype of $result

These methods are only useful for GETTING internal information, not setting
it.  No methods are currently available for SETTING these internal values.

GETTING AND SETTING LDAP SESSION OPTIONS

The get_option and set_option methods can be used to get and set LDAP
session options.

The following LDAP options can be set or gotten with these methods:
  LDAP_OPT_DEREF - Dereference
  LDAP_OPT_SIZELIMIT - Maximum Number of Entries to Return
  LDAP_OPT_TIMELIMIT - Timeout for LDAP Operations
  LDAP_OPT_REFERRALS - Follow Referrals

For both get and set operations, the first argument is the relivant
option.  In get, the second argument is a reference to a scalar variable
that will contain the current value of the option.  In set, the second
argument is the value at which to set this option.

Examples:
  $ld->set_option(LDAP_OPT_SIZELIMIT,50);
  $ld->get_option(LDAP_OPT_SIZELIMIT,\$size);

When setting LDAP_OPT_REFERRALS, the second argument is either LDAP_OPT_ON
or LDAP_OPT_OFF.  Other options require a number.

Both get_option and set_option return 0 on success and non-zero otherwise.

SSL SUPPORT

When compiled with the Mozilla SDK, this module now supports SSL.
I do not have an SSL capable server, but I'm told this works.  The
functions available are:

o ssl - Turn on SSL for this connection.
  Install I/O routines to make SSL over LDAP possible
o ssl_client_init($certdbpath,$certdbhandle)
  Initialize the secure parts (called only once)

Example:
  $ld = new Net::LDAPapi("host",LDAPS_PORT);
  $ld->ssl_client_init($certdbpath,$certdbhandle);
  $ld->ssl;

SETTING REBIND PROCESS

As of version 1.42, rebinding now works properly.

The set_rebind_proc method is used to set a PERL function to supply DN,
PASSWORD, and AUTHTYPE for use when the server rebinds (for referals,
etc...).

Usage should be something like:
  $rebind_ref = \&my_rebind_proc;
  $ld->set_rebind_proc($rebind_ref);

You can then create the procedure specified.  It should return 3 values.

Example:
  sub my_rebind_proc
  {
     return($dn,$pass,LDAP_AUTH_SIMPLE);
  }

SUPPORTED METHODS

abandon MSGID SCTRLS CCTRLS

This cancels an asynchronous LDAP operation that has not completed.  It
returns an LDAP STATUS code upon completion.

Example:

  $status = ldap_abandon($ld, $msgid); # XXX fix this

add DN ATTR SCTRLS CCTRLS

Begins an an asynchronous LDAP Add operation.  It returns a MSGID or undef
upon completion.

Example:

  %attributes = (
     "cn", ["Clayton Donley","Clay Donley"] #Add Multivalue cn
     "sn", "Donley",                #Add sn
     "telephoneNumber", "+86-10-65551234",  #Add telephoneNumber
     "objectClass", ["person","organizationalPerson"],
                      # Add Multivalue objectClass
     "jpegphoto", {"b",[$jpegphoto]},  # Add Binary jpegphoto
  );

  $entrydn = "cn=Clayton Donley, o=Motorola, c=US";

  $msgid = $ld->add($entrydn, \%attributes);

Note that in most cases, you will need to be bound to the LDAP server
as an administrator in order to add users.

add_s DN ATTR SCTRLS CCTRLS

Synchronous version of the 'add' method.  Arguments are identical
to the 'add' method, but this operation returns an LDAP STATUS,
not a MSGID.

Example:

  $ld->add_s($entrydn, \%attributes);

See the section on creating the modify structure for more information
on populating the ATTRIBUTES field for Add and Modify operations.

bind DN PASSWORD TYPE SCTRLS CCTRLS

Asynchronous method for binding to the LDAP server.  It returns a
MSGID.

Examples:

  $msgid = $ld->bind;
  $msgid = $ld->bind("cn=Clayton Donley, o=Motorola, c=US", "abc123");

bind_s DN PASSWORD TYPE SCTRLS CCTRLS

Synchronous method for binding to the LDAP server.  It returns
an LDAP STATUS.

Examples:

  $status = $ld->bind_s;
  $status = $ld->bind_s("cn=Clayton Donley, o=Motorola, c=US", "abc123");

compare DN ATTR VALUE SCTRLS CCTRLS

Asynchronous method for comparing a value with the value contained
within DN.  Returns a MSGID or undef.

Example:

  $msgid = $ld->compare("cn=Clayton Donley, o=Motorola, c=US", \
      $type, $value);

compare_s DN ATTR VALUE SCTRLS CCTRLS

Synchronous method for comparing a value with the value contained
within DN.  Returns an LDAP_COMPARE_TRUE, LDAP_COMPARE_FALSE or an error code.

Example:

  $status = $ld->compare_s("cn=Clayton Donley, o=Motorola, c=US", \
      $type, $value);

count_entries

Returns the number of entries in an LDAP result chain.

Example:

  $number = $ld->count_entries;

count_references MSG

Return number of references in a given/current message.

Example:

  $number = $ld->count_references

delete DN

Asynchronous method to delete DN.  Returns a MSGID or -1 if error.

Example:

  $msgid = $ld->delete("cn=Clayton Donley, o=Motorola, c=US");

delete_s DN

Synchronous method to delete DN.  Returns an LDAP STATUS.

Example:

  $status = $ld->delete_s("cn=Clayton Donley, o=Motorola, c=US");

dn2ufn DN

Converts a Distinguished Name (DN) to a User Friendly Name (UFN).
Returns a string with the UFN.

Since this operation doesn't require an LDAP object to work, you
could technically access the function directly as 'ldap_dn2ufn' rather
that the object oriented form.

Example:

  $ufn = $ld->dn2ufn("cn=Clayton Donley, o=Motorola, c=US");

explode_dn DN NOTYPES

Splits the DN into an array comtaining the separate components of
the DN.  Returns an Array.  NOTYPES is a 1 to remove attribute
types and 0 to retain attribute types.

Can also be accessed directly as 'ldap_explode_dn' if no session is
initialized and you don't want the object oriented form.

In OpenLDAP this call is depricated.

Example:

  @components = $ld->explode_dn($dn, 0);

explode_rdn RDN NOTYPES

Same as explode_dn, except that the first argument is a
Relative Distinguished Name.  NOTYPES is a 1 to remove attribute
types and 0 to retain attribute types.  Returns an array with
each component.

Can also be accessed directly as 'ldap_explode_rdn' if no session is
initialized and you don't want the object oriented form.

In OpenLDAP this call is depricated.

Example:

  @components = $ld->explode_rdn($rdn, 0);

first_attribute

Returns pointer to first attribute name found in the current entry.
Note that this only returning attribute names (ex: cn, mail, etc...).
Returns a string with the attribute name.

Returns an empty string when no attributes are available.

Example:

  $attr = $ld->first_attribute;

first_entry

Sets internal pointer to the first entry in a chain of results.  Returns
an empty string when no entries are available.

Example:

  $entry = $ld->first_entry;

first_message

Return the first message in a chain of result returned by the search
operation. LDAP search operations return LDAPMessage, which is a head
in chain of messages accessable to the user. Not all all of them are
entries though. Type of the message can be obtained by calling
msgtype(...) function.

get_all_entries RESULT

Returns result of the search operation in the following format
  (HASH)
  dn -> (HASH)
        key -> (ARRAY)

Example:
  my $all_entries_ref = $ld->get_all_entries;
  my %all_entries = %$all_entries_ref;

  foreach (keys %all_entries) {
      print "<$_> -> <".$all_entries{$_}.">\n";
      $entry = $all_entries{$_};

      local %entry_h = %$entry;
      foreach $k (keys %entry_h) {
          $values = $entry_h{$k};

          print "  <$k> ->\n";
          foreach $val (@$values) {
              print "     <$val>\n";
          }
      }
  }

get_dn MSG

Returns a string containing the DN for the specified message or an
empty string if an error occurs. If no message is specified then
then default entry is used.

Example:

  $dn = $ld->get_dn;

get_entry_controls MSG

Returns an array of controls returned with the given entry. If not MSG
is given as a paramater then current message/entry is used.

Example:

  my @sctrls = $ld->get_entry_controls($msg);
  foreach $ctrl (@sctrls) {
      print "control oid is ".$self->get_control_oid($ctrl)."\n";
  }

get_values ATTR

Obtain a list of all values associated with a given attribute.
Returns an empty list if none are available.

Example:

  @values = $ld->get_values("cn");

This would put all the 'cn' values for $entry into the array @values.

get_values_len ATTR

Retrieves a set of binary values for the specified attribute.

Example:

  @values = $ld->get_values_len("jpegphoto");

This would put all the 'jpegphoto' values for $entry into the array @values.
These could then be written to a file, or further processed.

is_ldap_url URL

Checks to see if a specified URL is a valid LDAP Url.  Returns 0 on false
and 1 on true.

Example:

  $isurl = $ld->is_ldap_url("ldap://x500.my.org/o=Org,c=US");

listen_for_changes BASEDN SCOPE FILTER ATTRS ATTRSONLY TIMEOUT SIZELIMIT COOKIE

Experimental function which implements syncrepl API in
refreshAndPersist mode. All but one arguments are the same as in search
function. Argument 'cookie' is the special one here. It must be specified
and is a file name in which cookie is to be stored. On a subsequent
restart of the seach only the newer results will be returned than those
indicated by the stored cookie. To refresh all entries, one would have to
remove that file.

This function is to be used in conjunction with next_changed_entries(...),
there you will also find example of its usage.

msgfree

Frees the current LDAP result.  Returns the type of message freed.

Example:

  $type = $ld->msgfree;

msgtype MSG

Returns the numeric id of a given message. If no MSG is given as a parameter
then current message is used. Following types are recognized: LDAP_RES_BIND,
LDAP_RES_SEARCH_ENTRY, LDAP_RES_SEARCH_REFERENCE, LDAP_RES_SEARCH_RESULT,
LDAP_RES_MODIFY, LDAP_RES_ADD, LDAP_RES_DELETE, LDAP_RES_MODDN,
LDAP_RES_COMPARE, LDAP_RES_EXTENDED, LDAP_RES_INTERMEDIATE, LDAP_RES_ANY,
LDAP_RES_UNSOLICITED.

Example:

  $type = $ld->msgtype

msgtype2str TYPE

Returns string representation of a given numeric message type.

Example:
  print "type = ".$ld->msgtype2str($ld->msgtype)."\n";

modify DN MOD

Asynchronous method to modify an LDAP entry.  DN is the DN to
modify and MOD contains a hash-table of attributes and values.  If
multiple values need to be passed for a specific attribute, a
reference to an array must be passed.

Returns the MSGID of the modify operation.

Example:

  %mods = (
    "telephoneNumber", "",     #remove telephoneNumber
    "sn", "Test",              #set SN to TEST
    "mail", ["me\@abc123.com","me\@second-home.com"],  #set multivalue 'mail'
    "pager", {"a",["1234567"]},  #Add a Pager Value
    "jpegphoto", {"rb",[$jpegphoto]},  # Replace Binary jpegphoto
  );

  $msgid = $ld->modify($entrydn,\%mods);

The above would remove the telephoneNumber attribute from the entry
and replace the "sn" attribute with "Test".  The value in the "mail"
attribute for this entry would be replaced with both addresses
specified in @mail.  The "jpegphoto" attribute would be replaced with
the binary data in $jpegphoto.

modify_s DN MOD

Synchronous version of modify method.  Returns an LDAP STATUS.  See the
modify method for notes and examples of populating the MOD
parameter.

Example:

  $status = $ld->modify_s($entrydn,\%mods);

modrdn2 DN NEWRDN DELETE

No longer available. Use function 'rename'.

modrdn2_s DN NEWRDN DELETE

No longer available. Use function 'rename_s'.

next_attribute

Similar to first_attribute, but obtains next attribute.
Returns a string comtaining the attribute name.  An empty string
is returned when no further attributes exist.

Example:

  $attr = $ld->next_attribute;

next_changed_entries MSGID ALL TIMEOUT

This function is too be used together with listen_for_changes(...) (see above).
It returns an array of Entries, which has just changed. Each element in this
array is a hash reference with two key value pairs, 'entry' which contains usual
entry and 'state' which contain one of the following strings 'present', 'add',
'modify' or 'delete'.

Example:

   my $msgid = $ld->listen_for_changes('', LDAP_SCOPE_SUBTREE, "(cn=Dm*)", NULL, NULL,
                                   NULL, NULL, $cookie);

   while(1) {
       while( @entries = $ld->next_changed_entries($msgid, 0, -1) ) {
           foreach $entry (@entries) {
               print "entry dn is <".$ld->get_dn($entry->{'entry'})."> ".
                   $entry->{'state'}."\n";
           }
       }
   }

next_entry

Moves internal pointer to the next entry in a chain of search results.

Example:

  $entry = $ld->next_entry;

next_message

Moves internal pointer to the next message in a chain of search results.

Example:

  $msg = $ld->next_message;

parse_result MSG FREEMSG

This function is used to retrieve auxiliary data associated with the
message. The return value is a hashtable containing following kevalue
pairs.
  'errcode'     -> numeric
  'matcheddn'   -> string
  'errmsg'      -> string
  'referrals'   -> array reference
  'serverctrls' -> array reference

The FREEMSG parameter determines whether the parsed message is freed
or not after the extraction. Any non-zero value will make it free the
message. The msgfree() routine can also be used to free the message
later.

perror MSG

If an error occurs while performing an LDAP function, this procedure
will display it.  You can also use the err and errstring methods to
manipulate the error number and error string in other ways.

Note that this function does NOT terminate your program.  You would
need to do any cleanup work on your own.

Example:

  $ld->perror("add_s");

rename DN NEWRDN NEWSUPER DELETE SCTRLS CCTRLS

Asynchronous method to change the name of an entry. NEWSUPER is a new
parent (superior entry).  If set to NULL then only the RDN is changed.
Set DELETE to non-zero if you wish to remove the attribute values from the
old name.  Returns a MSGID.

Example:

  $msgid = $ld->rename("cn=Clayton Donley, o=Motorola, c=US", \
      "cn=Clay Donley", NULL, 0);

rename_s DN NEWRDN NEWSUPER DELETE SCTRLS CCTRLS

Synchronous method to change the name of an entry. NEWSUPER is a new
parent (superior entry).  If set to NULL then only the RDN is changed.
Set DELETE to non-zero if you wish to remove the attribute values from the
old name.  Returns a LDAP STATUS.

Example:

  $status = $ld->rename("cn=Clayton Donley, o=Motorola, c=US", \
      "cn=Clay Donley", NULL, 0);

result MSGID ALL TIMEOUT

Retrieves the result of an operation initiated using an asynchronous LDAP
call.  It calls internally ldap_result function.  Returns LDAP message or
undef if error. Return value of ldap_result call stored in $ld->{"status"}
and is set -1 if something wrong happened, 0 if specified timeout was
exceeded or type of the returned message.

MSGID is the MSGID returned by the Asynchronous LDAP call.  Set ALL to
0 to receive entries as they arrive, or non-zero to receive all entries
before returning.  Set TIMEOUT to the number of seconds to wait for the
result, or -1 for no timeout.

Example:

  $entry = $ld->result($msgid, 0, 1);
  print "msgtype = ".$ld->msgtype2str($ld->{"status"})."\n";

result_entry

This function is a shortcut for moving pointer along the chain of entries
in the result. It is used instead of first_entry and next_entry functions.

Example
  while( $entry = $ld->result_entry ) {
      print "dn = ".$ld->get_dn($entry)."\n";
  }

result_message

This function is a shortcut for moving pointer along the chain of messages
in the result. It is used instead of first_message and next_message functions.

Example
  while( $msg = $ld->result_message ) {
      $msgtype = $self->msgtype($msg);
  }

search BASE SCOPE FILTER ATTRS ATTRSONLY

Begins an asynchronous LDAP search.  Returns a MSGID or -1 if an
error occurs.  BASE is the base object for the search operation.
FILTER is a string containing an LDAP search filter.  ATTRS is a
reference to an array containing the attributes to return.  An
empty array would return all attributes.  ATTRSONLY set to non-zero
will only obtain the attribute types without values.

SCOPE is one of the following:
      LDAP_SCOPE_BASE
      LDAP_SCOPE_ONELEVEL
      LDAP_SCOPE_SUBTREE

Example:

  @attrs = ("cn","sn");    # Return specific attributes
  @attrs = ();             # Return all Attributes

  $msgid = $ld->search("o=Motorola, c=US", LDAP_SCOPE_SUBTREE, \
      "(sn=Donley), \@attrs, 0);

search_s BASE SCOPE FILTER ATTRS ATTRSONLY (rewrite XXX)

Performs a synchronous LDAP search.  Returns an LDAP STATUS.  BASE
is the base object for the search operation.  FILTER is a string
containing an LDAP search filter.  ATTRS is a reference to an array
containing the attributes to return.  An empty array would return all
attributes.  ATTRSONLY set to non-zero will only obtain the attribute
types without values.

SCOPE is one of the following:
      LDAP_SCOPE_BASE
      LDAP_SCOPE_ONELEVEL
      LDAP_SCOPE_SUBTREE

Example:

  @attrs = ("cn","sn");    # Return specific attributes
  @attrs = ();             # Return all attributes

  $status = $ld->search_s("o=Motorola, c=US",LDAP_SCOPE_SUBTREE, \
      "(sn=Donley)",\@attrs,0);

search_st BASE SCOPE FILTER ATTRS ATTRSONLY TIMEOUT (rewrite/remove XXX)

Performs a synchronous LDAP search with a TIMEOUT.  See search_s
for a description of parameters.  Returns an LDAP STATUS.  Results are
put into RESULTS.  TIMEOUT is a number of seconds to wait before giving
up, or -1 for no timeout.

Example:

  $status = $ld->search_st("o=Motorola, c=US",LDAP_SCOPE_SUBTREE, \
      "(sn=Donley),[],0,3);

unbind SCTRLS CCTRLS

Unbind LDAP connection with specified SESSION handler.

Example:

  $ld->unbind;

url_parse URL

Parses an LDAP URL into separate components.  Returns a HASH reference
with the following keys, if they exist in the URL:

host      - LDAP Host
port      - LDAP Port
dn        - LDAP Base DN
attr      - LDAP Attributes to Return (ARRAY Reference)
filter    - LDAP Search Filter
scope     - LDAP Search Scope
options   - Mozilla key specifying LDAP over SSL

Example:

  $urlref = $ld->url_parse("ldap://ldap.my.org/o=My,c=US");

url_search URL ATTRSONLY

Perform an asynchronous search using an LDAP URL.  URL is the LDAP
URL to search on.  ATTRSONLY determines whether we are returning
the values for each attribute (0) or only returning the attribute
names (1).  Results are retrieved and parsed identically to a call
to the search method.

Returns a non-negative MSGID upon success.

Example:

  $msgid = $ld->url_search($my_ldap_url, 0);

url_search_s URL ATTRSONLY

Synchronous version of the url_search method.  Results are retrieved
and parsed identically to a call to the search_s method.

Returns LDAP_SUCCESS upon success.

Example:

  $status = $ld->url_search_s($my_ldap_url, 0);

url_search_st URL ATTRSONLY TIMEOUT

Similar to the url_search_s method, except that it allows a timeout
to be specified.  The timeout is specified as seconds.  A timeout of
0 specifies an unlimited timeout.  Results are retrieved and parsed
identically to a call to the search_st method.

Returns LDAP_SUCCESS upon success.

Example:

  $status = $ld->url_search_s($my_ldap_url,0,2);
