Seems odd.  So long as the attributes are in your dictionary and the  
NAS is sending them, FreeRADIUS should be logging them.  If it's not,  
then it must be doing some type of filtering on specific attributes.   
NAS-Port-Id is a standard RADIUS attribute and not a VSA, so I don't  
see what the big deal is.
