Now when we try to add ldap settings we get back 400 Bad Request error from pressing ‘Test Ldap connection’ button from GUI:

Pressing button: POST /api/v1/ldap.testConnection HTTP/1.1

Any help?

Hi!

Can you get any outstanding logs? Remember to increase log verbosity. This is the return of the test, so it will give you the 400 and under the hood, at the logs, might how what exactly happened, even with a LDAP error code.

Let me know if this helps.

Thanks!

I did try to increase log verbosity, but I did not get anything more. In my understanding original POST is already somehow malformed and Rocket newer does any ldap connection. That error response was from tcpdump sniff and system did not try any e.g. ldap connections. Now I can not understand how GUI request can be wrong in a such basic setup without any modification?
