Hello Everyone!

I'm facing a strange issue with Ldaps integration inside System -> Access -> Servers, when i'm trying to integrate my LDAPS server, and i cannot find anything in the logs.

Steps:

• Go to System -> Access -> Servers
• Configure HostURL: x.x.x.x
• Configure Transport: SSL (Port 636)
• Configure Bind etc etc etc
• Click on Test

Expected Behavior:
Test Successful message

Current Behavior:
Error Message: Curl error: (3) URL rejected: No host part in the URL

Notes:
if i click on  Authentication containers select button, i get all the authentication contains correctly from my LDAPS server.

UPDATE 3/NOV/2025
I clicked on save and when inside the System -> Access -> Testers logged in with a user and i was able to authenticate. so is it a bug in the test inside LDAPS?

The help text for the host address reads:

QuoteNOTE: When using SSL, this hostname MUST match the Common Name (CN) of the LDAP server's SSL Certificate.

So you cannot use an IP address there - which I guess you did, because you wrote "x.x.x.x"?

Hello Patrick,

Thank you for the help!

Nop i used an FQDN and the CN matches the SSL Certificate, and i clicked test the issue kept on happening, i was like mehh let me try to save and use the Testers, and it worked fine in the testers !
