Yes, research the problem. On the DSA [LDAP server] is the slapd server listening on the expected port? netstat --listen --tcp --program Given the contents of /etc/openldap/ldap.conf [or wherever your client LDAP config is] - does the hostname specified there resolve? Is the port specified the same the server is listening on? Can you "telnet hostname port-number" from the client and get a connection?

Re: [Samba] openldap integration failed after power cut
Hi running ldapsearch -x on the primary LDAP server fails, it gives [root@servername ~]# ldapsearch -x ldap_bind: Can't contact LDAP server (-1) And yet on that server the Zimbra instance appears to be fine. Can you suggest any further diagnosis of the LDAP on that server, or action I might take?

Can you use "ldapsearch" or a GUI Ldap browser/editor (e.g. Apache Directory Studio) to make sure that your primary LDAP server really is working . Verify that the credentials are good.
