Much better :-). Is server_config[] be the appropriate place to  
define this? (mainconfig.c:103)

That sounds better. I assume I just need to ensure that (1) %{My- 
Attribute} is defined somewhere in the dictionary (the internal  
server dictionary?) and (2) the attribute is added to the reply list  
by whatever module is being used for AuthZ. Is there anything else?
