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.
