The following message is displayed when you login into a text console via ssh or locally:
Using username "root". Using keyboard-interactive authentication. Password: Univention DC Master 4.2-2: The UCS management system is available at https://someserver.domain.com/ (192.168.2.10) You can log into the Univention Management Console - the principal tool to manage users, groups, etc. - using the "Administrator" account and the password selected for the root user on the master domain controller. root@someserver:~#
The message seems to suggest that we use the “root” user password for the “Administrator” account. These two accounts are different and need NOT have the same password.
I actually tried this, when I had an issue logging in to the console, hence this warning. You have to login using “root” account with root-password.
