(Visual FoxPro) NTLM Client and Server Code

Demonstrates the NTLM authentication algorithm for both client and server.

IF (lnSuccess <> 1) THEN

ENDIF

*  UnlockComponent only needs to be called once on the 1st object instance.

loNtlmServer = CreateObject('Chilkat_9_5_0.Ntlm')

*  The NTLM protocol begins by the client sending the server
*  a Type1 message.

loNtlmClient.Workstation = "MyWorkstation"
lcType1Msg = loNtlmClient.GenType1()

? "Type1 message from client to server:"
? lcType1Msg

*  If the server wishes to examine the information embedded within the
*  Type1 message, it may call ParseType1.
*  This step is not necessary, it is only for informational purposes..
lcType1Info = loNtlmServer.ParseType1(lcType1Msg)

? "---"
? lcType1Info

*  The server now generates a Type2 message to be sent to the client.
*  The Type2 message requires a TargetName.  A TargetName is
*  the authentication realm in which the authenticating account
*  has membership (a domain name for domain accounts, or server name
*  for local machine accounts).
loNtlmServer.TargetName = "myAuthRealm"

lcType2Msg = loNtlmServer.GenType2(lcType1Msg)
IF (loNtlmServer.LastMethodSuccess <> 1) THEN
    ? loNtlmServer.LastErrorText
    RELEASE loNtlmClient
    RELEASE loNtlmServer
    CANCEL
ENDIF

? "Type2 message from server to client:"
? lcType2Msg

*  The client may examine the information embedded in the Type2 message
*  by calling ParseType2, which returns XML.  This is only for informational purposes
*  and is not required.
lcType2Info = loNtlmClient.ParseType2(lcType2Msg)

? "---"
? lcType2Info

*  The client will now generate the final Type3 message to be sent to the server.
*  This requires the Username and Password:
loNtlmClient.UserName = "test123"
loNtlmClient.Password = "myPassword"

lcType3Msg = loNtlmClient.GenType3(lcType2Msg)
IF (loNtlmClient.LastMethodSuccess <> 1) THEN
    ? loNtlmClient.LastErrorText
    RELEASE loNtlmClient
    RELEASE loNtlmServer
    CANCEL
ENDIF

? "Type3 message from client to server:"
? lcType3Msg

*  The server may verify the response by first "loading" the Type3 message.
*  This sets the various properties such as Username, Domain, Workstation,
*  and ClientChallenge to the values embedded within theType3 message.
*  The server may then use the Username to lookup the password.
*  Looking up the password is dependent on your infrastructure.  Perhaps your
*  usernames/passwords are stored in a secure database.  If that's the case, you would
*  write code to issue a query to get the password string for the given username.
*  Once the password is obtained, set the Password property and then
*  generate the Type3 response again.  If the server's Type3 response matches
*  the client's Type3 response, then the client's password is correct.

lnSuccess = loNtlmServer.LoadType3(lcType3Msg)
IF (lnSuccess <> 1) THEN
    ? loNtlmServer.LastErrorText
    RELEASE loNtlmClient
    RELEASE loNtlmServer
    CANCEL
ENDIF

*  The Username property now contains the username that was embedded within
*  the Type3 message.  It can be used to lookup the password.
lcClientUsername = loNtlmServer.UserName

*  For this example, we'll simply set the password to a literal string:
loNtlmServer.Password = "myPassword"

*  The server may generate the Type3 message again, using the client's correct
*  password:
lcExpectedType3Msg = loNtlmServer.GenType3(lcType2Msg)

? "Expected Type3 Message:"
? lcExpectedType3Msg

*  If the Type3 message received from the client is exactly the same as the
*  expected Type3 message, then the client must've used the same password,
*  and authentication is successful.
