When the default authentication domain cannot be used, you need to create a new one.
In most cases, the default authentication domain is enough. In the following scenarios, you need to plan more authentication domains:
If a new authentication domain is configured, users will need to suffix their user names with the authentication domain (format: Login Name@Authentication Domain) during login. If the default authentication domain is used, users need to enter only their login names.
When the user group associated with the authentication domain is changed to the default group, the FW deletes the original group (whose name is the same as the authentication domain) and its subgroups. Exercise caution when you perform the operation.
