OpenLDAP custom port not saved

Hi,

I have integrated an OpenLDAP Server Directory and it was all fine and working. From one day to another, the syncing does not work anymore. I have no clue when the problem first occured but I think it has something to do with the release upgrade from 15 to 16 (current version is 16.0.26).

Now the error message when syncing is Invalid credentials but nothing changed with credentials. The ldap is listening on custom ports (7389 without encryption and 7636 with ssl encryption). Maybe it is a bug so when I change the port via the gui and submit and then once again edit the entry there always is port 389 and not the changed one. If I change other parameters they will be still there, only the port is always at standard 389.

Can I edit this as well in the cli?
