I currently have an Umbraco installation that I have set up to use an external login to authenticate users to use the Backoffice. Login works fine, but when I get into the backoffice the Identity I had created gets replaced with an UmbracoBackOfficeIdentity. Because of this, if someone logs out of the external source from a different site, they can still use the Backoffice even though they are not logged into the external source that I want to be verified. Is there a way to add traits to the UmbracoBackOfficeIdentity or a different way to verify that the User has the token I would verify.
