FAQ: TYPO3 Single Sign-On

Why do I get "User Mapping not configured for this user" ?

Normally... because no user mapping is configured for this user :-)
i.e. because this Single Sign-On content element is configured for "user mapping", but the current FE user is not in the mapping tables.

But... currently this messages also appears if there is no FE user logon at all, and the user navigates to a Single Sign-On content element !
This behaviour will certainly change in upcoming versions. But on the other hand, the situation should not occure anyway, since a Single Sign-On content element should always be access-protected (like "show at any login" etc.)
