This check item is very similar to Prefix above, but checks for the presence of a certain suffix in the user name. If it is not present the check item will fail. If it is present, it will be removed from the user name and accepted. This is most useful in DEFAULT items to handle different variations of the same users name, but with different reply attributes.

In this example, there might be a user mikem in the System authentication method. These user entries will allow mikem.ppp to log in as a PPP user, and mikem.slip to login as a Slip user:

DEFAULT     Suffix = .ppp, Auth-Type = System
            Service-Type = Framed-User,
            Framed-Protocol = PPP,
            Framed-IP-Address = 255.255.255.254,
            Framed-MTU = 1500
DEFAULT     Suffix = .slip, Auth-Type = System
            Service-Type = Framed-User,
            Framed-Protocol = SLIP,
            Framed-IP-Address = 255.255.255.254,
            Framed-Compression = None
