This is very similar to our situation:  you need to authorize based  
on some combination of a user's attributes that are found in LDAP,  
but that *aren't* present for comparison in the RADIUS request.  Our  
solution is to use rlm_perl for the comparison.

You already have part of the solution:  you've got LDAP retrieving  
the relevant LDAP data into locally-defined RADIUS attributes.  Now  
you just need to write a perl script to check the appropriate members  
of the %RAD_CHECK hash, and configure an Autz-Type that uses your  
LDAP module, followed by your rlm_perl module.
