I am facing an issue with GCP and unmanaged users. After using the transfer tool to invite someone in the organization, he unfortunately didn't read the email and the invitation timed out. For some reasons I was not able to resend the invitation so I instead decided to create a new user. However he keeps getting the following error now:
I checked the logs and I figured he is not using the same login type as other peoples, SAML is me and Google password being the user having the issue.
Can anyone help me on how to enforce using SAML on the authentication? I am using Azure AD as IdP.
Thanks
This worked for me so I'll leave it here in case anyone struggle with the same issues.
