You are right, we use rlm_realm and it leaves User-Name unadulterated.

This sounds like maybe the *inner* auth User-Name is realmless and 
making it's way out into outer.reply.  When you use 'User-Name' in 
post-auth{} you will get reply:User-Name rather than request:User-Name 
if I remember correctly.

The fix is to *reject* inner-authentications that are realm-less.

Cheers
