i am trying to login with standard password to dc-p2 via web service but it reports The authentication has failed, check error log

Assistant2026-01-21T08:17:03.269Z

Thinking

The user is trying to log into dc-p2 via a web service but authentication is failing. I need to check the error logs on dc-p2 to see what's happening. This could be related to the Univention Management Console (UMC) or Apache web service.

$ Bash

Check UMC server logs

ssh root@dc-p2.sa.out.ba "journalctl -u univention-management-console-server -n 50 --no-pager 2>&1 | tail -50"

Assistant2026-01-21T08:17:05.858Z

$ Bash

Check UMC log file for auth errors

ssh root@dc-p2.sa.out.ba "tail -100 /var/log/univention/management-console-server.log 2>&1 | grep -iE 'error|fail|auth|login' | tail -30"

Thinking

The UMC server is having issues with LDAP TLS certificate verification. The error shows "self-signed certificate in certificate chain" which is the same issue we saw before. The UMC server needs to be restarted to pick up the new certificates, and possibly sssd service as well since pam_sss is also failing.

Let me restart the relevant services.

Assistant2026-01-21T08:17:15.287Z

The UMC server still has cached certificate issues. The error is "self-signed certificate in certificate chain" - same as before. Let me restart the relevant services.

Good - sssd restarted cleanly without any TLS errors. Let me check the sssd configuration to see where it gets its CA certificate from.

Assistant2026-01-21T08:17:47.241Z

$ Bash

Check sssd TLS configuration

ssh root@dc-p2.sa.out.ba "grep -iE 'ldap_tls|certificate' /etc/sssd/sssd.conf 2>/dev/null"

Tool reply2026-01-21T08:17:48.914Z

certificate_verification = no_ocsp,soft_crl,crl_file=/var/www/ucsCA.crl
ldap_tls_cacert = /etc/univention/ssl/ucsCA/CAcert.pem
ldap_tls_reqcert = demand
ldap_tls_cipher_suite = HIGH:MEDIUM:!aNULL:!MD5:!RC4

Assistant2026-01-21T08:17:52.722Z

Thinking

SSSD is correctly pointing to the CA certificate. The restart should have picked up the new CA. Let me try a user lookup to see if sssd can now connect to LDAP.

Assistant2026-01-21T08:17:53.685Z

$ Bash

Test user lookup via sssd

ssh root@dc-p2.sa.out.ba "getent passwd Administrator && echo 'User lookup successful'"

Tool reply2026-01-21T08:17:55.464Z

Administrator:x:2002:5000:Administrator:/home/Administrator:/bin/bash
User lookup successful

Assistant2026-01-21T08:17:58.424Z

Thinking

User lookup works. The authentication should work now. Let me check if there are any new errors when trying to authenticate.

Assistant2026-01-21T08:17:58.969Z

User lookup works now. Please try logging in again via the web interface. Let me also check if there are any remaining issues.

Assistant2026-01-21T08:17:59.803Z

$ Bash

Check latest UMC logs

ssh root@dc-p2.sa.out.ba "tail -5 /var/log/univention/management-console-server.log"

Assistant2026-01-21T08:18:04.720Z

Thinking

The last error was before the restart at 09:17:18. The server restarted cleanly (DEBUG_INIT shows initialization). The user should now be able to log in. Let me wait for them to try or check if they get an error.

Assistant2026-01-21T08:18:06.231Z

Services are now running cleanly. The last errors were before the restart at 09:17:18.

Please try logging in now - the sssd, slapd, and UMC services have all been restarted with the new certificates.

If it still fails, let me know and I'll check the new error messages.

User2026-01-21T08:21:35.117Z

it works now

Assistant2026-01-21T08:21:38.092Z

Thinking

The user confirmed that the login is now working. Let me provide a brief confirmation.

Assistant2026-01-21T08:21:40.956Z
