I would like to use LDAP to be able to authorize a user so if there have a certain attribute I can return a radius AVP with a VLAN ID in the access-accept. This would be used for allowing access to licensed library resources. However, I am not sure if I can do this the way my LDAP stuff is set up.

The attribute that has the data I need is multi-valued.

StudentAA, StudentDBRN, and StudentFLNT (continuing and incoming students regardless of enrollment; includes detached study);
EnrolledStudentAA, EnrolledStudentDBRN, EnrolledStudentFLNT (enrolled in at least one credit hour for ""current"" term; next term information is used during gap between terms)
AlumniAA, AlumniDBRN, AlumniFLNT (any person who has completed at least one semester in a degree-granting program)
FacultyAA, FacultyDBRN, FacultyFLNT (defined as academic, instructional, and research appointments; includes emeritus faculty)
RegularStaffAA, RegularStaffDBRN, RegularStaffFLNT (current appointment with a status of active, suspended, short-work break, leave, or paid leave);
TemporaryStaffAA, TemporaryStaffDBRN, TemporaryStaffFLNT (current appointment with a status of active, suspended, short-work break, leave, or paid leave)
Retiree (retired from any U-Mcampus, regardless of other appoints that may still be active)
SponsoredAffiliateAA, SponsoredAffiliateDBRN, SponsoredAffiliateFLNT (has at least one departmental sponsorship).

However, only 5 of them (StudentAA, EnrolledStudentAA, FacultyAA, RegularStaffAA and TemoraryStaffAA) should get the radius AVP and be allowed access. However, when I query I get something like the following

ldapsearch -h ldap.umich.edu

-ZZ -z0 -x -D <cut> -b ou=people,dc=umich,dc=edu -LLL -s sub uniqueid=<username> umichinstroles

dn: uid=royboy,ou=People,dc=umich,dc=edu

umichinstroles: RegularStaffAA

umichinstroles: AlumniFLNT

So that is not realyy a group membership.

Is this something I will be able to do? If not natively can folks mention other options/solutions?
