TACACS+ external authentication service
Rack Power Manager software supports TACACS+ external authentication. Once the
TACACS+ authentication service is added, you may map TACACS+ users to the Rack Power
Manager software database by using the Add User Account wizard. The username added in the
Rack Power Manager software should match the username configured in the TACACS+ server.
For more information about adding users, see Adding User Accounts on page 211.
You may choose to associate users with internal Rack Power Manager software groups to
control group level access rights. Or, you may choose to map users to external TACACS+
groups and control group level access rights using the TACACS+ service. There are two types
of external TACACS+ groups that can be used: the TACACS+ standard privilege level
attribute, or a custom group name attribute. To map users to external TACACS+ groups, use the
Rack Power Manager software Add User Group wizard and specify the group type. For more
information, see Adding User-defined User Groups on page 224.
To add a TACACS+ external authentication service:
1. On the TACACS+ server that will be used as an external authentication service, add the
Rack Power Manager server as a TACACS+ client. Make a note of the configured shared
secret and the available authentication type(s) on the TACACS+ server.
2. From the Rack Power Manager Explorer, Click the Users tab.
3. Click Authentication Services in the top navigation bar. The User Authentication Services
window will open.
4. Click Add. The Add Authentication Service Wizard will appear.

a. Type a 1-64 character name for the TACACS+ authentication service.
