The user is able to log into the console randomly. Sometimes the user is able to , sometimes he/she is unable. Same when syncing users from AD into user groups. The directory services test connection success rate is also randomThe Cloudconnector log shows the following error: CloudConnector.DirectoryService.DirectoryService.SearchUsers Directory call failed. System.DirectoryServices.Protocols.LdapException: Error code:81System.DirectoryServices.Protocols.LdapException: The LDAP server is unavailable.
LDAP Error Code: 81 typically means that the ACC has trouble speaking to the Domain Controller over the configured port in the Directory Services Settings.Firstly from the ACC server try to telnet the Domain Controller over the port configured in the Directory Services settings in the console. If this fails constantly it points to a network issue where the configured port is not open between the ACC and Domain Controller.If the issue is intermittent where it succeeds and then fails at different stages on the ACC server, check to see if there is an anti virus program running. (In this case it was trend micro).Turn off all services associated with the anti-virus software and restart the service. You should now be able to get access without any random failures.you can then re-active the anti virus software on the ACC to confirm to the user that this is the cause of the issue
