S4 connector rejected (again)

This connector stuff is really pushing me to my limits … may be I’m getting a bit old :neutral_face:

So - here’s my scenario. Two servers (main DC and Backup DC) patched to the latest version.

Since I did probably something I should not (deleting stuff in /var/lib/samba/sysvol) I get s4 connector rejects:

UCS rejected

    1:   UCS DN: cn=Console Logon,cn=Builtin,dc=msbe,dc=local
          S4 DN: cn=console logon,cn=builtin,DC=msbe,DC=local
         Filename: /var/lib/univention-connector/s4/1557252472.699478

S4 rejected

    1:    S4 DN: CN=Console Logon,CN=Builtin,DC=msbe,DC=local
         UCS DN: cn=console logon,cn=builtin,dc=msbe,dc=local

	last synced USN: 467246

The s4connector.log shows:

Unfortunately I cannot understand what’s going on and how to fix it. Please shed some light on this. As the system is currently not in production I am not sure whether it works as expected. Currently I suspect issues with executing logon scripts which may relate to this error.

Thanks for any help - Martin

Hi @mschlee,

been there, done that: Problem: S4-Connector Rejects about DN: cn=Console Logon

Wow, that was fast. And it seems to fix the problem.

I am wondering, however, why this error showed up all of a sudden. At least I try to understand what’s going on here.
