As part of Jamf Pro’s single-sign on (SSO) logins, there’s an option to bypass the SSO login using the following URL:

https://your.jamf.pro.server.here:8443/?failover

This URL is designed to let you bypass the SSO login page and take you to Jamf Pro’s own login, so that if your SSO provider is having a bad day, you can still log into your Jamf Pro server.

For those wanting to make sure that that their folks are only using SSO for logins, this can seem like a security hole. Fortunately, there’s a way to plug it. For more details, please see below the jump.

If you want to block access to the failover login for a specific user or a group, here’s how to do this:

1. Go to Settings: System Settings: Jamf Pro User Accounts & Groups
2. Identify the user or group where you want to block their ability to login using the the failover URL.
3. Go to Jamf Pro Server Actions and locate the Sso Settings checkboxes.
4. Uncheck the Update checkbox for the Jamf Pro Server Actions: Sso Settings.
5. Save changes.

This change will do two things:

1. Prevent that account from being able to edit the Single Sign On settings in Settings: System Settings.
2. Remove that account’s ability to log in to the Jamf Pro server using the the ?failover login page.

Once the change is made, you should be able to test by trying to log into the Jamf Pro server with an affected account using the ?failover login page. If all goes well, access should be blocked.
