Hello @Paul Bomboy
Thank you for reaching out. Error 400: admin_policy_enforced is an G Suite Policy error and not an Azure AD error. When login with super admin credentials we authenticate the credentials your G-Suite Environment. If we receive any error during this phase it needs to be reviewed and worked upon target app system.
I tried to look up for this error and found that the error message «Error 400: admin_policy_enforced» is caused by changes in permissions that haven't been accepted.
You can find more details about this error in G-Suite Admin Console Help documentation. Few that I found are listed below:
