LDAP Authentication

I am trying to enable LDAP authentication against an OpenLDAP server and need some advice on how to get this up and running. Can someone help me out? Heres the content of the authentication portion of my xwiki.cfg file in following the configuration instructions here: http://www.xwiki.org/xwiki/bin/view/Dev/LDAPIntegrationAD You will note that I have asked some questions throughout the file. xwiki.authentication=form xwiki.authentication.validationKey=totototototototototototototototo xwiki.authentication.encryptionKey=titititititititititititititititi xwiki.authentication.cookiedomains=xwiki.com,wiki.fr xwiki.authentication.useip=false xwiki.authentication.ldap=1 xwiki.authentication.ldap.server=ldap.cait.org xwiki.authentication.ldap.port=389 #xwiki.authentication.ldap.check_level= <? Wasn't sure of what this should be. Need more info on what this is and does.> xwiki.authentication.ldap.base_DN=ou=People,o=cait.org #xwiki.authentication.ldap.bind_DN= <blank for anonymous access What's the proper way to indicate 'blank'?> #xwiki.authentication.ldap.bind_pass= <blank for anonymous access> #xwiki.authentication.ldap.UID_attr=uid The ones I have commented out are also commented out currently in the config file. Should I comment some out or change others? Tim
