## Symptoms

- * The user configured LDAP account unit servers to work with SSL.
* Although the SSL fingerprint was changed on the server, it was not updated in SmartConsole.
* The following error appears in the PDP debug:  
  `@ . . . [Date & Time] ldap_ctx_fingerprint_check: ldap_async: SSL finger print does not match`

## Cause

AD Query sometimes requires a specific server to resolve LDAP group membership. If the SSL fingerprint verification fails, a fail back to another server will not occur.
