Authentication and Authorization (AA) Overview
Users of CC-SG can be locally authenticated and authorized on the CC-
SG or remotely authenticated using the following supported directory
servers:
• Microsoft Active Directory (AD)
• Netscape's Lightweight Directory Access Protocol (LDAP)
• TACACS+
• RADIUS
Any number of remote servers can be used for external authentication.
For example, you could configure three AD servers, two iPlanet (LDAP)
servers, and three RADIUS servers.
Only AD can be used for remote authorization of users.
LDAP implementations use LDAP v3.
Flow for Authentication
When remote authentication is enabled, authentication and authorization
follow these steps:
1. The user logs into CC-SG with the appropriate username and
password.
2. CC-SG connects to the external server and sends the username and
password.
