  The point is you write an LDAP query.  Using LDAP syntax.  It's not
about bash, Perl, or Python.  It's about LDAP.

  Then, use the LDAP query in FreeRADIUS:

	update request {
		Realm := "%{ldap:... LDAP QUERY...}"

  The LDAP query should return the domain for the user.  The above
example puts the domain into the "Realm" attribute.

  Then... use the Realm attribute in later queries.
