  i am currently trying to setup xwiki on taomcat 5.5/mysql. until now its
  doing quite well :)
  my next step is to get ldap authentication against an active directory
  working. i followed
http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Authentication#HLDAPCon…
  and some postings on the mailing list but i cant get it to work.
  i either end up with:
  com.xpn.xwiki.plugin.ldap.XWikiLDAPException: Error number 0 in 5: LDAP
  bind failed with LDAPException.
  Wrapped Exception: Invalid Credentials
  or worse (with in my eyes the propper config):
  WARN  LDAP.XWikiLDAPAuthS
  erviceImpl   - LDAP authentication failed.
  java.lang.NullPointerException

  Could you copy/paste your configuration.
  i've done ldap auth on several other tools (apache/subversion,
  bugzilla). there i used two accounts: one allowed to bind to the active
  directory and do searches and the useraccount itself.
  in the xwiki config i can only see the user logging in is used to bind
  to the ldap server? 
  You can define a user able to bind to the active directory using
  "bind_DN" and "bind_pass" properties and it will search for provided
  login in ldap based on "UID_attr" property
  is the documentation current for xwiki 1.3.2.9174? or can someone give
  me a hint to make this work? 
  Are you sure you use xwiki-core 1.3.2 version, I can't find in the
  code what could make NullPointerException at
  XWikiLDAPAuthServiceImpl.java:256
  thanks a lot
  regards
  werner
