Cannot change data source credentials to anything different than current credentials because of SSO

Hi Seb_Lz ,

You didn't mention the context - are you in the service, the gateway or the desktop and the type of security settings for SSO that you have implement.  However, I did find these documents that might help:

https://docs.microsoft.com/en-us/power-bi/connect-data/service-gateway-sso-overview

If you are using Kerberos:

https://docs.microsoft.com/en-us/power-bi/connect-data/service-gateway-sso-kerberos

OR, if you are actually wanting to sign in from the very beginning with the generic userid, you can go here:

https://powerbi.microsoft.com/en-us/landing/signin/   and sign in with that generic userid.  Or, on the desktop, sign in in the top right corner with the generic userid.

I would appreciate Kudos if my response was helpful. I would also appreciate it if you would Mark this As a Solution if it solved the problem. Thanks!
