You notice some issues on your server and the ldapsearch command tells about the ldap server not reachable:
root@school:~# ldapsearch -x ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)
Make sure the correct ucr variable is set so the components try to access the correct server. Additionally make sure to have the correct server given if configured through policies:
root@school:~# ucr set ldap/server/name=gymli21 Setting ldap/server/name W: ldap/server/name is overridden by scope "ldap" [...]
If you get the
overridden by scope "ldap" configure the correct server in your global policy.
