Hopefully the final update – now it shows:

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