/*
app_name - the name of the application
realm - The realm for this application
optionname - the name of the option
default - the default value if it isn't found.
variable - a pointer to the returned value

the way this appears in the configuration file is:

[appdefaults]

        option = false

        REALM = {
                option = false
                app_name = {
                        option = true
                }
        }

        app_name = {
                option = true
        }


For telnet, the app name I use is "telnet".  The realm is the realm of the
default principal.

The options I use in the Unix telnet are:

        forward - Forward your credentials if TRUE
        forwardable - Make the credentials on the remote end forwardable if TRUE
        encrypt - Attempt to negotiate encryption if TRUE
        autologin - Attempt to perform AUTHENTICATION option if true
        forceencrypt - Fail if encryption does not succeed

  ftp is "ftp" and only 'forward' is defined.

#ifdef COMMENT
Undocumented function:

From: "Maxim S. Shatskih" <maxim__s@mtu-net.ru>
Looks like calling NtCreateToken from your service running under
LocalSystem is the only way.
The function is completely undocumented - looks like it accepts parameters
like user's SID, all groups SID's (to which this user belongs) and all
privilige
IDs - which this user posesses.
Calling the function will bypass NT security & log the specified user on
without
any password validation (you are free to use your own instead of NTs
standard) & audit trail. In fact, this means that you implement your own LSA
:-)


// untested
HCRYPTPROV hProvider = 0;
BYTE randomBytes[128];
CryptAcquireContext(&hProvider, 0, 0, PROV_RSA_FULL, CRYPT_VERIFYCONTEXT);
CryptGenRandom(hProvider, sizeof(randomBytes), randomBytes);
