Description


This article describes a solution where it is not possible to select a specific VDOM as the only option when creating a TACACS+ or RADIUS administrator account.


Scope


FortiADC and FortiADC VM.


Solution


Example:

The FortiADC has 3 VDOMs (root, vd1, and vd2).

There is a requirement to create administrator account with access to only VDOM vd1.

However, when creating the account, FortiADC gives an error when the VDOM root is not selected, which defeats the original requirement for only the VDOM 'vd1'.

The error is due to the selected TACACS+ or RADIUS servers configured in the VDOM root.

The TACACS+ or RADIUS servers need to be created in the respective VDOM. For this example, it is VDOM vd1.

After selecting the correct TACACS+ or RADIUS servers respectively, it no longer gives an error when only VDOM 'vd1' is selected.
