Controller Based WLANs

How does user role assignment work?

Product and Software: This article applies to all Aruba controllers running ArubaOS 3.1 and later.

 

A client is assigned a user role by one of several methods. A user role assigned by one method may take precedence over a user role assigned by a different method.

 

The methods of assigning user roles are, from lowest to highest precedence:

1)  The initial user role for unauthenticated clients is the "initial role" configured in AAA profile for a virtual AP.

2)  The user role can be derived from user attributes upon the client's association with an AP (this is known as a user-derived role). You can configure rules that assign a user role to clients that match a certain set of criteria. For example, you can configure a rule to assign the role "VoIP-Phone" to any client that has a MAC address that starts with bytes xx:yy:zz. User-derivation rules are executed before client authentication.

3)  The user role can be the default user role configured for an authentication method, such as 802.1x or VPN. For each authentication method, you can configure a default role for clients who are successfully authenticated using that method.

4)  The user role can be derived from attributes returned by the authentication server and certain client attributes (this is known as a server-derived role). If the client is authenticated via an authentication server, the user role for the client can be based on one or more attributes returned by the server during authentication, or on client attributes such as SSID (even if the attribute is not returned by the server). Server-derivation rules are executed after client authentication.

5)  The user role can be derived from Aruba Vendor-Specific Attributes (VSA) for RADIUS server authentication. A role derived from an Aruba VSA takes precedence over any other user roles.
