hello, I want to add access to xwiki only for users from special posixGroup in ldap. So I have added option: #-# only members of the following group will be verified in the LDAP #-# otherwise only users that are found after searching starting from the base_DN xwiki.authentication.ldap.user_group=cn=xwiki,ou=services,dc=xxx,dc=com all works fine but in logs i get exeption when i dont have some user in this group: com.xpn.xwiki.XWikiException: Error number 8001 in 8: LDAP user usertest does not belong to LDAP group cn=xwiki,ou=services,dc=xxx,dc=com. at
