# External User Group Configuration

A device can connect to one or more external authentication servers, or “auth servers”, on which you store user accounts. For more information on external authentication servers, see Auth Server List.

An External User is a user—Auth, L2TP, XAuth, Admin—that is created on an external authentication server. You cannot create external users on the device, but you can create external user groups.

An Auth user can be a member of up to four user groups on a RADIUS server. An Auth user who belongs to more than one group is required to supply a username and password only once, before being granted access to the resources defined for each group in which the user is a member.

### To Create an External User Group

1. Enter a name for the group.

2. Select the type of the user group—Auth, IKE, L2TP, XAuth. You can select a combination of types.

3. Click OK to save your settings.
