Mailcow LDAP test fails immediately during setup
’s LDAP setup fails as soon as the test button is pressed. The problem does not appear to be caused by a issue or DNS.
The failure happens so quickly that the settings may be rejected before a real connection is made. There is little clear information available about this exact behavior, and the test button itself may also be part of the problem.
Key points
- ’s LDAP test returns a connection failure immediately.
- A issue and DNS have already been ruled out.
- The fast failure may point to a settings check before a real connection happens.
- The test button itself may be unreliable in this case.
- Logs, port checks, and exact settings would be needed to diagnose it.
