 * $Log: pldap.cxx,v $
 * Revision 1.17  2004/05/24 12:02:49  csoutheren
 * Add function to permit setting a limit on the number of results returned
 * from an LDAP query. Change the default number of results to unlimited,
 * rather than MAX_INT which apparently is clamped to some arbitrary low value.
 * Thanks to Damien Sandras
 *
 * Revision 1.16  2004/04/09 06:52:17  rjongbloed
 * Removed #pargma linker command for /delayload of DLL as documentations sais that
 *   you cannot do this.
 *
 * Revision 1.15  2004/02/23 23:52:19  csoutheren
 * Added pragmas to avoid every Windows application needing to include libs explicitly
 *
 * Revision 1.14  2004/02/04 09:37:00  rjongbloed
 * Fixed memory leak and race condition, thanks Rossano Ravelli
 *
 * Revision 1.13  2004/01/17 17:45:29  csoutheren
 * Changed to use PString::MakeEmpty
 *
 * Revision 1.12  2003/07/15 12:12:11  csoutheren
 * Added support for multiple values in a single attribute string
 *    Thanks to Ravelli Rossano
 *
 * Revision 1.11  2003/07/12 00:10:40  csoutheren
 * Fixed problem where Modify routines were calling Add, thanks to Ravelli Rossano
 *
 * Revision 1.10  2003/06/06 09:14:01  dsandras
 *
 * Test that a search result has been returned before calling ldapresult2error.
 *
 * Revision 1.9  2003/06/05 23:17:52  rjongbloed
 * Changed default operation timeout to 30 seconds.
 *
 * Revision 1.8  2003/06/05 05:29:30  rjongbloed
 * Fixed LDAP bind authentication methods, thanks Ravelli Rossano
 *
 * Revision 1.7  2003/04/17 08:34:48  robertj
 * Changed LDAP structure output so if field is empty it leaves it out
 *   altogether rather then encoding an empty string, some servers barf.
 *
 * Revision 1.6  2003/04/16 08:00:19  robertj
 * Windoes psuedo autoconf support
 *
 * Revision 1.5  2003/04/07 11:59:52  robertj
 * Fixed search function returning an error if can't find anything for filter.
 *
 * Revision 1.4  2003/04/01 07:05:16  robertj
 * Added ability to specify host:port in opening an LDAP server
 *
 * Revision 1.3  2003/03/31 03:32:53  robertj
 * Major addition of functionality.
