Chapter 6: Authentication Services 95
TACACS+ external authentication service
DSView 3 software supports TACACS+ external authentication. Once the TACACS+
authentication service is added, you may map TACACS+ users to the DSView 3 software database
by using the Add User Account wizard. The username added in the DSView 3 software should
match the username configured in the TACACS+ server. For more information about adding users,
see Adding User Accounts on page 231.
You may choose to associate users with internal DSView 3 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 DSView 3 software Add User Group
wizard and specify the group type. For more information, see Adding User-defined User Groups on
page 242.
To add a TACACS+ external authentication service:
