Remote authentication
Fabric OS supports user authentication through the local user database or one of the following
external authentication services:
• Remote authentication dial-in user service (RADIUS)
• Lightweight Directory Access Protocol (LDAP) using Microsoft Active Directory in Windows or
OpenLDAP in Linux.
• Terminal Access Controller Access-Control System Plus (TACACS+)
Remote authentication configuration
A switch can be configured to try one of the supported remote authentication services (RADIUS,
LDAP, or TACACS+) and local switch authentication. The switch can also be configured to use only a
remote authentication service, or only local switch authentication.
