Troubleshooting

Error: contact your administrator

If you get an error message suggesting you contact your administrator, try these steps:

1. Go to the Microsoft Azure AD user profile for the users.

2. In Contact Info, check whether the Email field is blank.

If it is blank, there are two possible solutions:

• In User Principal Name, if the Identity field is an email address, try changing the User Attributes & Claims to email = user.userprincipalname.

• In Contact Info, if none of the Alternate email fields are blank, try changing the User Attributes & Claims to email = user.othermail.

If you still have login issues, you can use the SAML Tracer browser extension to check the process step by step. If this doesn’t work, get in touch with our support team at support@Aiven.io.
