Facing login issue in Open Project

We have downloaded and want to configure the open Project VM machine with Server
Univention Corporate Server 4.2-1:

We are using default credentials :- user- admin
password- admin
but facing the login issues.

Kindly share the default credentials.

Machine Type : Vmware Image.

Where did you get the image from? 4.2.1 sounds pretty outdated…
And where did you find the documentation about the credentials? Did you have a look here? See: https://wiki.univention.de/index.php/Operation_and_Configuration_of_the_UCS_system_in_VMware_or_VirtualBox

There should run a wizard on first bootup where you configure your credentials…

Usually UCS uses Administrator as username instead of admin. And I would try to use “univention” as password…
