[ScreenOS] Radius Authentication Using Domain Name Stripping



Article ID: KB7837 KB Last Updated: 11 Aug 2010Version: 3.0
XAuth VPN using external authentication with Radius server.
Radius request does not get sent

Beginning with ScreenOS 5.2.0, you can specify on the Juniper Firewall to strip all characters with a domain name preceded by a separator character.  This allows an administrator to specify a standard, like SMTP addresses, for usernames, and still be able to send just the username portion of the SMTP address without explicitly telling users to only specify their username.

For example, assume you have the following configuration:

set auth-server "" username separator "@" number 1
set auth-server "" username domain ""

When a user enters, the Firewall will strip off for the auth request.  Only "joe" will be sent to the radius server.

However, if a user only enters "joe", the debug auth all will show the following debug messages:

## 10:53:53 : auth_ext: domain name in username joe is joe, in auth server
## 10:53:53 : auth_ext: domain name in username joe is joe, in auth server, DOESN'T MATCH

Workaround: Either specify the entire SMTP address in the username field, or remove the username separator and username domain fields from the auth field in the WebUI.
