I want to integrate xwiki login with my active directory login.Basically i want to use same credentials for xwiki that i am using for window login.Here is my ldap configuration(as per examples given at http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Authentication http://platform.xwiki.org/xwiki/bin/view/AdminGuide/LDAPAuthenticationUseCa… ) xwiki.authentication.authclass=com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl xwiki.authentication.ldap=1 xwiki.authentication.ldap.server=10.215.30.20 xwiki.authentication.ldap.port=389 // all other values i have kept default xwiki.authentication.ldap.bind_DN=cn={0},department=USER,department=INFORMATIK,department=1230,o=MP xwiki.authentication.ldap.bind_pass={1} xwiki.authentication.ldap.base_DN= xwiki.authentication.ldap.UID_attr=cn But when i login to xwiki with my window credentials , i get below error(though i am able to ping 10.215.30.20 server):- com.xpn.xwiki.plugin.ldap.XWikiLDAPException: Error number 0 in 5: LDAP bind failed with LDAPException. Wrapped Exception: Invalid Credentials Any idea what can be probable reason for this?
