Found a couple more events in the production.log: I, [2022-02-07T09:44:25.667133 #177250] INFO -- : [ac1312f2-4de1-4727-9922-26cd7e9f7442] [177250:200.57] Not bound as CN=obs-svc,OU=service,DC=xyz,DC=local: Can't contact LDAP server E, [2022-02-07T09:44:25.667178 #177250] ERROR -- : [ac1312f2-4de1-4727-9922-26cd7e9f7442] [177250:200.57] Unable to bind to any LDAP server: dc1.xyz.local I, [2022-02-07T09:44:25.667200 #177250] INFO -- : [ac1312f2-4de1-4727-9922-26cd7e9f7442] [177250:200.57] Unable to connect to LDAP server Some observation: - OBS unable to connect to LDAP server. - Firewall is disabled on both OBS server and Domain Controller. - DC is pingable via IP and FQDN. - Able to connect via ldapsearch tool and search the whole directory. - Domain Controller not showing any event ID 4625 in the Security Event logs, which would provide more clue in regards the issue (e.g. wrong username or password, etc) Questions: - What kind of calls does OBS make in order to communicate with LDAP server(s)? - Is there a verbose log that can help me figure out this issue?
