Migrating from UCS sso to Azure

Ill keep this simple. Have recently inherited a Univention server (UCS 5.0.2) and new to the whole OS.

Customer currently has M365 hosted Email and the login process is SSO back to UCS. I belive it may actually be Federated, so may need to break federation.

The goal is to stop m365 using SSO to the local UCS. M365 login to be its own identity.

UCS does, dhcp, dns, user/group management.
