Active Directory Interactive (with MFA support) users can not login in 2026.3.3 after Upgrade from 2026.2.18

Hi,

We made a database copy Azure SQL database from our 2026.2.18.0 RDM version and did a fresh/new install with the Beta 2026.3.3 on a client. Setup the workspace settings to this database and logged in with de SQL admin user account.
The upgrade process was completed, the (SQL) account was able to log in, and the vault(s) were available.

If we now log in with the usual user account(s), Login mode = Active directory Interactive (with MFA support) in this 2026.3.3 Client version we get an error. Same error when testing this Workspace in the setting, see screenshot below:


If I log in now using the same account via a current client version (2026.2.18) to this 2026.3.3 test data source, this error does not occur, and we can simply use and work with this 2026.3.3 test database.

Can you provide support with this, or is there a specific reason why we are encountering this error logging in to RDM when upgrading to this beta version for this type of account(s)?

Regards, Marcel
