AAA, NAC, Guest Access & BYOD

Answer

 ClearPass supports several authentication and authorization sources – including Active Directories, LDAP stores, SQL stores, Kerberos stores and so on. A key omission here is RADIUS as an authentication/authorization source, which will allow ClearPass to query a third-party RADIUS server for the purposes of authentication & authorization.

Clearpass currently until 6.4 does not support this functionality and is scheduled to be part of 6.5 release.

This capability will allow ClearPass to interact with another standards-driven identity store, and provides ClearPass with a transparent interface that masks the details of the actual identity store behind the RADIUS interface.

Networks that interact with multiple customers commonly use RADIUS as a transport for identity data. This masks the details of an identity store that may lie behind the RADIUS interface, such as a Kerberos Identity Store. In situations such as this, RADIUS provides a transparent interface into multiple identity stores, thereby allowing ClearPass to interact with such a store in a seamless manner.
