When users sign in to their My Apps portal and RADIUS authentication is enabled, a special login dialog
box appears in the browser. Users enter their RADUS authentication user name and passcode in the
login dialog box. If the RADIUS server issues an access challenge, the identity manager service displays
a dialog box prompting for a second passcode. Currently support for RADIUS challenges is limited to
prompting for text input.
After a user enters credentials in the dialog box, the RADIUS server can send an SMS text message or
email, or text using some other out-of-band mechanism to the user's cell phone with a code. The user can
enter this text and code into the login dialog box to complete the authentication.
If the RADIUS server provides the ability to import users from Active Directory, end users might first be
prompted to supply Active Directory credentials before being prompted for a RADIUS authentication
username and passcode.
Prepare the RADIUS Server
Set up the RADIUS server and then configure it to accept RADIUS requests from the
Directories Management service.
Refer to your RADIUS vendor's setup guides for information about setting up the RADIUS server. Note
your RADIUS configuration information as you use this information when you configure RADIUS in the
service. To view the type of RADIUS information required to configure Directories Management see
Configure RADIUS Authentication in Directories Management.
You can set up a secondary Radius authentication server to be used for high availability. If the primary
RADIUS server does not respond within the server timeout configured for RADIUS authentication, the
request is routed to the secondary server. When the primary server does not respond, the secondary
server receives all future authentication requests.
Configure RADIUS Authentication in Directories Management
You enable RADIUS software on an authentication manager server. For RADIUS authentication, follow
the vendor's configuration documentation.
Prerequisites
Install and configure the RADIUS software on an authentication manager server. For RADIUS
authentication, follow the vendor's configuration documentation.
You need to know the following RADIUS server information to configure RADIUS on the service.
n
IP address or DNS name of the RADIUS server.
n
Authentication port numbers. Authentication port is usually 1812.
n
Authentication type. The authentication types include PAP (Password Authentication Protocol), CHAP
(Challenge Handshake Authentication Protocol), MSCHAP1, MSCHAP2 (Microsoft Challenge
Handshake Authentication Protocol, versions 1 and 2).
