HOWTO Commands

The authcli tool will test authentication, showing whether or not
the authentication succeeds, and if so, showing the user properties
as well. The authentication request will be routed through the
current authentication module, i.e. PAM, LDAP, RADIUS, or Local
Users.
./authcli -u -p
or
./authcli -u
The latter form will interactively prompt for a password.
