Pattern Matching in users file

Do I need to predefine the attribute name somewhere before 
I attempt to create it in the users file?

Are you referring to the doc/processing_users_file?  If so, perhaps I
misunderstood the bullet within it that reads:

- The check pairlist of the request is replaced by the tmpcheck pairlist
  (this is the same as: the check pairlist from the usersfile entry is
   appended to the pairlist of the request)

The phrase in parentheses is what made me think I could add attributes
to the request.  Is this statement incorrect or am I interpreting it
differently than the author intended?  The first part of the bullet
matches what you said and what I experienced.

>  If you want to add an attribute to the request, you have to use the

I don't think that will work for me because the hints file doc.
states it adds attributes solely based upon prefix or suffix of
the username.  I want to add an attribute based upon the value of
Cisco-AVPair.  Am I misinterpreting the doc. for hints also?

Thanks again for your help Alan.
