Hi! Yes. To make sure I copied xwiki.cfg from old to new version again and restart xwiki. In xwiki.cfg in LDAP section uncommented only next strings xwiki.authentication.authclass=com.xpn.xwiki.user.impl.LDAP.XWikiLDAPAuthServiceImpl xwiki.authentication.ldap.server=127.0.0.1 xwiki.authentication.ldap.port=389 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.fields_mapping=last_name=sn,first_name=givenName,email=mail xwiki.authentication.ldap.update_user=1 xwiki.authentication.ldap.trylocal=1 But in XWikiPreferences some parameters not match to xwiki.cfg (ldap server and etc). It was on old version too. -- View this message in context: http://xwiki.475771.n2.nabble.com/LDAP-service-is-not-available-after-update...
