The attributes are coming from the database, from the radgroupreply 
table. My configuration is basically the default one with minor 
adjustments. I use attr_filter to not send attributes from one vendor to 
another, but I already checked that and it is not the source of the 
problem. I think it may be caused by the bug reported by our friend in a 
previous message.

Thanks a lot.
