group authorization

i am close, but need a pointer...
i am using rlm_krb5 for authentication and rlm_ldap for authorization.
when i add a radiusReplyItem of Cisco-AVPair = "shell:priv-lvl=15" to my
user object, i am able to log into my switch.
i want to have the radiusReplyItem given in a reply when the user is a
member of a specific group in ldap, but i seem to be having trouble with
that. it seems that when the ldap query is made for the group
membership, the "short" version of the uid (uid=brendan) is being used
and not matching. the actual member "value" in the group is the "long"
version of the uid (uid=brendan,ou=Users,dc=bpk2,dc=com). is there
something i can do to use the "long" version?
