authtest - Test the Courier Authentication Library

authtest is a command-line diagnostic utility for the Courier Authentication Library.  authtest requires
       at least one argument: loginid.  authtest sends the authentication request to the Courier Authentication
       Library, then displays the results. Only root may use authtest utility, and the Courier Authentication
       Library daemon (authdaemond) must already be started.

       If only one argument is provided, the authentication request displays the account information for
       loginid, if found.

       If two arguments are provided, password must match loginid's existing password.

       If three arguments are provided, loginid's password is changed to newpassword, but only if password
       matches the existing password.

       These three basic authentication requests can be used to troubleshoot the authentication library's
       configuration.
