User's Manual
• Click Find a group on external authentication service to choose from the list of
groups on the external authentication service. If the list of groups contains more than
5000 entries, a message will indicate that not all items are displayed.
You may filter the list by using the Filter button and the adjacent text field. If
you are using an Active Directory Server, you can choose the filter method.
Click Filter in Rack Power Manager Server (legacy) to use a traditional
filtering method; see Filtering information in a window on page 29.
-or-
Click Filter in Active Directory Server to use a modified filtering method that
only provides matches to the filter string based on the common name (CN) of
the group. This filter uses LDAP search syntax. This method passes the filter
to the AD server allowing the AD server to return the matches, which
provides faster results than the legacy filter method.
Select one or more external authentication service groups from the list.
6. Select a role for the user group(s). See Built-in User Groups on page 43 for information
about user roles.
7. From the Preemption Levels menu, select a preemption level from 1-4; the higher the
number, the higher the preemption level.
8. Click Finish.
TACACS+ external authentication services
To add a TACACS+ user group:
1. Click the Users tab. Click Groups in the top navigation bar. Click User-Defined in the side
navigation bar. The User Groups - User Defined window will open.
2. Click Add. The Add User Group wizard will appear.
3. The Select Authentication Service window will open. This window lists all authentication
services that may be used to authenticate the user group when the user logs in. Select an
appropriate TACACS+ authentication service from the list. Click Next.
4. If the TACACS+ service you selected is configured to use the privilege level attribute
method, the Specify External Group Name window will open and display a list of privilege
levels 0-15 (the higher the number, the higher the level of access).
Select a privilege level from the list. The Rack Power Manager server will assign a
group name based on the privilege level you select. For example, if you choose level
7, the group name will be Privilege Level 7.
Click Next.
