Revision history for ApacheDBI.

0.83  August 08, 1999
	- make ping configurable, proposed by 
	  Gunther Birznieks <gunther@nhgri.nih.gov>
	- the environment variable REMOTE_GROUPS uses as separator $; 
	  instead of comma.
	- change $user_sent_quoted to $user_sent when checking for 
	  placeholders (Michael Smith <mjs@iii.co.uk>)
	- bug-fix for encrypted passwords, which have never been taken
	  from the cache. Spotted by Yves BLUSSEAU <yves.blusseau@sncf.fr>.

0.82  June 03, 1999
	- bug-fix spotted by "Dale Manemann" <manemann@dubuque.net>:
	  correct the password handling for the case, where the password has
	  been changed in the database and the old password is still cached.
	- proposal from Honza Pazdziora <adelton@informatics.muni.cz>:
	  add PerlCleanupHandler in Apache::DBI, which issues a rollback 
	  unless AutoCommit is on. 
	- changed behavior of AuthzDBI: the first match of a
	  requirement is sufficient for successful authorization.
	  Prior to this release, all requirement lines had to 
	  be fulfilled. 
	- proposal from Rauznitz Balazs <jomagam@yahoo.com>:
	  new function all_handlers() in Apache::DBI.pm. Returns 
	  all cached database handles, so that other handlers can 
	  perform tasks on them.
	- proposal from Michael Smith <mjs@iii.co.uk>: new 
	  configuration option Auth_DBI_placeholder. Setting this 
	  option to true, will use placeholders for the given userid 
	  in the SELECT statements. This will speedup database access. 
	- proposal from "Jordi 'Matematic' Salvat" <jordi@webarna.com>:
	  replace AuthName with a summary of all attributes relevant
	  for the select statements. This still keeps the userid entries
	  in the cache unique, but solves the problem with different 
	  AuthNames which eventually forces the user to authenticate 
	  several times. 
	- new configuration option Auth_DBI_expeditive from
	  "Jordi 'Matematic' Salvat" <jordi@webarna.com>. 
	  When authorization fails, AuthzDBI returns AUTH_REQUIRED
	  as default. With Auth_DBI_expeditive set to "on" it returns
	  FORBIDDEN if access is denied. Hence this can be distinguished 
	  from the case, where the user just mistyped the password.
	- applied patch from Ask Bjoern Hansen <ask@valueclick.com>:
	  get rid of some annoying "Use of uninitialized value ..."
	- applied patch from Joshua Chamas <joshua@chamas.com>:
	  use eval{ping} to prevent using an invalid database handle.
	- added 'use Apache;' to Apache::DBI.pm as proposed by
          Michael Smith <mjs@iii.co.uk>.
	- implemented multiple passwords per userid as proposed by
	  dan hammer <dhammer@verio.net>.
	- applied patch for case-insensitive user-ids from 
	  <grussell@wiley.com>. 
	- implement proposal from Honza Pazdziora <adelton@informatics.muni.cz>:
	  Auth_DBI_casesensitive replaced by Auth_DBI_uidcasesensitive and 
	  Auth_DBI_pwdcasesensitive. 
	- applied patch from fdc@cliwe.ping.de (Frank D. Cringle):
	  prevent "Use of uninitialized value warning" in error.log.
	- work-around for mod_perl problem spotted by Mike Hayward 
	  <hayward@loup.net>: when building mod_perl as dso, Apache::DBI 
	  was always skipping the connection cache.

0.81  Sep 08, 1998
	- Cache entries consider the AuthName to distinguish 
	  between identical user-ids in different authorization 
	  realms. 

0.80  Jul 26, 1998
	- applied patch from Anto Prijosoesilo <anto@inet.co.th>:
	  change second argument for crypt function from $salt
	  to $passwd in order to be compatible with BSD.
	- applied patch for Apache::DBI.pm from Randy Harmon 
	  <rjharmon@uptimecomputers.com>: reject database connect 
	  during server startup.
	- call CleanupHandler in Authen DBI and AuthzDBI only if 
	  cache_time is configured.

0.79  Jun 06, 1998
	- implemented a simple caching mechanism in AuthenDBI as 
	  well as in AuthzDBI. Per default this cache is disabled 
	  and can be enabled by setting Auth_DBI_cache_time > 0. 
	  YOU NEED AT LEAST VERSION apache_1.3b6 !
	- applied patch from Jeff Baker <jeff@godzilla.tamu.edu>
	  fix menu item for DBI connections that are made using 
	  the Oracle TNS listener.
	- implemented proposal from Leslie Mikesell <les@Mcs.Net>
	  change group-handling in AuthzDBI. All groups related to
	  the given user are selected at once and then put into a 
	  comma-separated list. This list is compared with the 
	  required groups. 
	  Depending upon the existence of Auth_DBI_grp_table, the 
	  SQL-select looks either in the pwd_table or in the 
	  grp_table for the groupid. PLEASE CHECK THE MODULE 
	  DOCUMENTATION AND YOUR .htaccess !

0.78  February 18, 1998
        - applied patch from "B. W. Fitzpatrick" <fitz@onShore.com>
          DBI calls connect always with 4 parameters, even if they
          are empty. This results in an error with DBD-Informix.
        - added '$dbh->disconnect' before 'return SERVER_ERROR;'
          (fyodor@mp.aha.ru <Fyodor Krasnov>).
	- added optional where-clause in AuthenDBI as well as
          in AuthzDBI (Helmut Patay <Helmut.Patay@mch.sni.de>).

0.77 January 18, 1998
        - applied patches from Doug MacEachern:
          o new method  Apache::DBI->connect_on_init()
          o set environment variable REMOTE_GROUP in AuthzDBI.pm.

0.76 December 18, 1997
	- removed unused variable from AuthzDBI.pm

0.75 November 02, 1997
	- strip trailing blanks from password for 
	  fixed-length data type
	- new token: 'Auth_DBI_casesensitive'
	  (Hakan Tandogan <hakan@iconsult.com>
        - fixed bug when using attributes in connect method
        - fixed bug which appeared with perl5.004_04

0.74 August 15, 1997
        - new module: AuthzDBI for Authorization,
          (supports group authorization)
        - complete rewrite of AuthenDBI.
        - configuration directives and functionality 
          of both modules are supposed to be identical
          with mod_auth_msql of the apache daemon.
	- adapted to new DBI connect syntax
	- changed names of config vars to be more
          consistent with other authentication modules.
          PLEASE ADAPT YOUR CONFIGURATION !!!
