RADIUS Identity Stores

RADIUS server is a third-party server that supports the RADIUS interface. RADIUS identity store, which is part of ACS, connects to the RADIUS server.

RADIUS servers are servers that come with a standard RADIUS interface built into them and other servers that support the RADUIS interface. ACS 5.3 supports any RADIUS RFC 2865-compliant server as an external identity store. ACS 5.3 supports multiple RADIUS token server identities.

For example, the RSA SecurID server and SafeWord server. RADIUS identity stores can work with any RADIUS Token server that is used to authenticate the user. RADIUS identity stores use the UDP port for authentication sessions. The same UDP port is used for all RADIUS communication.

Note For ACS to successfully send RADIUS messages to a RADIUS-enabled server, you must ensure that the gateway devices between the RADIUS-enabled server and ACS allow communication over the UDP port. You can configure the UDP port through the ACS web interface.
