LDAP error: Error:Error - LDAP bind : ldap_bind(): Unable to bind to server: Can't contact LDAP server

ssudosu commented 3 months ago

Hello, I'm testing the new version (3.1.2.28) of Teampass on Docker.

-> I did a clean installation. -> I configured LDAP and can synchronize and create LDAP users without any issues. --> But when I try to log in with an LDAP user, it returns the error "LDAP error: Error:Error - LDAP bind : ldap_bind(): Unable to bind to server: Can't contact LDAP server" however, sometimes I can log in with the same user without making any changes.

-> I can ping my LDAP server inside the VM and inside the Teampass container.

Has anyone else experienced this issue and managed to resolve it?

I have this issue too; I logged an issue here two weeks ago and have had no response.

ssudosu commented 3 months ago

We'll have to wait and see if someone can solve the problem. I still haven't found a solution.

Having the same issue here after upgrading to 3.1.1.26. Was fine before the upgrade. I tried the update to ldap_suffix and ldap_domain_dn and that still didn't fix the issue.

JanuszU commented 1 month ago

version 3.1.2.45 LDAP login works fine without SSL on port 389 turning on SSL and switching to 636 or 3268 shows: "ldap_bind(): Unable to bind..."

any ideas how to debug ?
