NOS Authentication
Overview NOS authentication is an alternative to RADIUS authentication for local
and dial-in users using Novell or Windows NT networks. NOS
authentication allows you to control network access by remote users
through an existing network security mechanism.
NOS authentication has the following limitations:
■
It does not support ARAP and PPP clients using CHAP authentication.
■
Spaces are not allowed in the user ID and password fields.
■
User ID and password fields are case-sensitive.
■
The NOS authentication server does not assign configuration
information to the user. Instead, the RAS 1500 assigns each
NOS-authenticated user the “default” user profile.
