// $Log: not supported by cvs2svn $
// Revision 1.3  2004/02/02 05:36:29  rurban
// Simplification and more options, but no passwd or admin protection yet.
//
// Revision 1.2  2004/02/01 09:14:11  rurban
// Started with Group_Ldap (not yet ready)
// added new _AuthInfo plugin to help in auth problems (warning: may display passwords)
// fixed some configurator vars
// renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
// changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
// USE_DB_SESSION defaults to true on SQL
// changed GROUP_METHOD definition to string, not constants
// changed sample user DBAuthParams from UPDATE to REPLACE to be able to
//   create users. (Not to be used with external databases generally, but
//   with the default internal user table)
//
// fixed the IndexAsConfigProblem logic. this was flawed:
//   scripts which are the same virtual path defined their own lib/main call
//   (hmm, have to test this better, phpwiki.sf.net/demo works again)
//
// Revision 1.1  2004/02/01 01:04:34  rurban
// Used to debug auth problems and settings.
// This may display passwords in cleartext.
// DB Objects are not displayed anymore.
//
// Revision 1.21  2003/02/21 04:22:28  dairiki
// Make this work for array-valued data.  Make display of cached markup
// readable.  Some code cleanups.  (This still needs more work.)
//
// Revision 1.20  2003/01/18 21:19:24  carstenklapp
// Code cleanup:
// Reformatting; added copyleft, getVersion, getDescription
//

// (c-file-style: "gnu")
// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
