Hi folks, Question:
I want to allow only authorized people to access specific NASes. And the authorization needs to come from Active Directory (LDAP2). Obviously, I have access to NAS-IP-Address coming in from the Access-Request. The problem is that our AD organizes authorized staff into groups which are presented using the "memberOf" attribute. When I fetch that from AD, someone like me who belongs to multiple groups gets an ugly mess that looks like this: 07715580 Fri Feb 11 17:03:48 2022 710905: DEBUG: LDAP got memberOf: CN=Development Team,CN=Users,DC=MYDOMAIN,DC=mycompany, DC=com CN=OUC,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=My Engineering,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=My Alarms,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=Admin Access,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=All Staff,CN= Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=Management List,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com CN=Graphic Developme nt,CN=Users,DC=MYDOMAIN,DC=mycompany,DC=com The only part that tells me I have access to a particular NAS is the "Admin Access" entry. I could just do a clumsy regex to look for a match. But the documentation: https://www.open.com.au/radiator/ref/AuthAttrDef_AuthByLDAP2.html#Host_AuthByLDAP2-24 says something about support for multi-valued LDAP attributes. But I don't understand the data structure; I can't seem to parse on commas or spaces. Does this type of data qualify for the "multi-valued" parsing that is advertised in the documentation? In other words, if I did a check for "DC=com CN=Admin Access", would it find a match? So, the second part of my problem is that obviously "DC=com CN=Admin Access" won't match the NAS-IP-Address. What I really need is logic like: IF AD.memberOf(user) matches "DC=com CN=Admin Access" AND NAS-IP-Address = A.B.C.D THEN PASS ELSE IF AD.memberOf(user) matches "DC=com CN=Regular Access" AND NAS-IP-Address = W.X.Y.Z THEN PASS ELSE FAIL Guidance on how to solve this problem is greatly appreciated!
