Authentication

Authentication
The Digi CM unit supports multiple methods of user authentication, including
local, TACACS+, RADIUS, RADIUS Down-Local, LDAP, Kerberos, and
Custom PAM. The authentication protocol you use depends on your
environment.
Configuring Authentication Methods for Port Access
You can choose between having a single authentication method, such as
RADIUS, or an authentication method where a Local authentication service is
used in addition to the RADIUS, LDAP, TACACS+ server, or Kerberos. These
options are listed when you configure the Digi CM unit for authentication. To
configure the Digi CM unit for authentication, do the following:
1. Access the web interface.
2. Under the Serial port heading, choose Configuration.
3. Choose All or an Individual port > Authentication.
