Hi agustavo,
I guess this is our server-password-change (default all 21 days) changing the server password. If this fails, you may get this consequenses. You can deactivate the server-password-change:
Or xou can check
`/var/log/univention/server_password_change.log
With
zgrep 'Proceeding with regular server password change scheduled for today' /var/log/univention/server_password_change.log*
you get the relevant logfiles.
Hope that helps!
