TACACS+ external authentication service
DSView software supports TACACS+ external authentication. Once the TACACS+
authentication service is added, you may map TACACS+ users to the DSView software
database by using the Add User Account wizard. The username added in the DSView software
should match the username configured in the TACACS+ server. For more information about
adding users, see Adding User Accounts on page 263.
You may choose to associate users with internal DSView 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
software Add User Group wizard and specify the group type. For more information, see Adding
User-defined User Groups on page 277.
To add a TACACS+ external authentication service:
1. On the TACACS+ server that will be used as an external authentication service, add the
DSView 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 DSView Explorer, Click the Users tab.
