After finding this issue, I felt like I have to look at the different principals more granularly.

It is now showing:

• authentication & impersonation configuration settings
• type of Membership and Role provider
• trust level
• type of current IPrincipal/IIdentity on Context.User
• type of current IPrincipal/IIdentity on Thread.CurrentPrincipal 
• process identity
• thread identity (if impersonating)
• Context.User name and authentication type
• Thread.CurrentPrincipal name and authentication type
• IIS authentication outcome used by FileAuthorizationModule
• client certificate (and the embedded UPN if from a Windows enterprise CA)
• roles (for Windows-, Roles- and GenericPrincipal)
