Chapter 2 Understanding Cisco Access Registrar

Cisco Access Registrar Hierarchy

UserLists and Groups

Cisco Access Registrar lets you organize your user community through the configuration objects UserLists, users, and UserGroups.

•Use UserLists to group users by organization, such as Company A and Company B. Each list contains the actual names of the users.

•Use users to store information about particular users, such as name, password, group membership, base profile, and so on.

•Use UserGroups to group users by function, such as PPP, Telnet, or multiprotocol users. Groups allow you to maintain common authentication and authorization requirements in one place, and have them referenced by many users.

For more information about UserLists and UserGroups, refer to Access Registrar Server Objects in the Cisco Access Registrar User’s Guide.

Profiles

Cisco Access Registrar uses Profiles that allow you to group RADIUS attributes to be included in an Access-Accept packet. These attributes include values that are appropriate for a particular user class, such as PPP or Telnet user. The user’s base profile defines the user’s attributes, which are then added to the response as part of the authorization process.

Although you can use Group or Profile objects in a similar manner, choosing whether to use one rather than the other depends on your site. If you require some choice in determining how to authorize or authenticate a user session, then creating specific profiles, and specifying a group that uses a script to choose among the profiles is more flexible. In such a situation, you might create a default group and then write a script that selects the appropriate profile based on the specific request. The benefit to this technique is each user can have a single entry, and use the appropriate profile depending on the way they log in.

For more information about Profiles, refer to Access Registrar Server Objects in the Cisco Access Registrar User’s Guide.

Scripts

Cisco Access Registrar allows you to create scripts you can execute at various points within the processing hierarchy.

•Incoming scripts—enable you to read and set the attributes of the request packet, and set or change the Environment dictionary variables. You can use the environment variables to control subsequent processing, such as specifying the use of a particular authentication service.

•Outgoing scripts—enable you to modify attributes returned in the response packet.

For more information about Scripts, refer to Access Registrar Server Objects in the Cisco Access Registrar User’s Guide.

Services

Cisco Access Registrar uses Services to let you determine how authentication, authorization, and/or accounting are performed.
