wb,
My LDAP administrator didn't think I needed any
settings for the following
configuration options, so these are currently commented out:
#xwiki.authentication.ldap.check_level
#xwiki.authentication.ldap.bind_DN
#xwiki.authentication.ldap.bind_pass
#xwiki.authentication.ldap.fields_mapping
In my limited experience with this, I found that you need a simple bind to make it work.
