Proget SAML + Active Directory SAML Users and Groups Page Not available

[jblaine_9526]

With the new multiple user directories option, I'm unable to use to the SAML Users and Groups tab of the security configuration to identify SAML Users and Groups.

I've configured multiple directories (Active Directory and a SAML directory) and the SAML Users and Groups tab shows up when i enable the SAML directory, however I get a 500 error page when I click on the tab.

The error that shows up in the logs is this:

Note: when I look in the database, the directoryID for my SAML directory is actually 6.
