Cannot connect to server configured for CAM (Active directory hook) using the Cognos TM1 API

问题

Is there anyway to connect to a server that uses CAM authentication in VBA using the TM1 API?

I've tried the following code based on the answer found here:
SystemServerCAMSecurityRequired error when authenticating using Cognos

Dim credentials(1 To 3) As Long
credentials(1) = TM1ValString(hPool, Trim(CAMNamespace), 0)
credentials(2) = TM1ValString(hPool, Trim(ClientName), 0)
credentials(3) = TM1ValString(hPool, Trim(ClientPassword), 0)
vCredentials = TM1ValArray(hPool, credentials, 3)
hServer = TM1SystemServerConnectWithCAMNamespace(hPool, vServerName, vCredentials)

However, this causes Excel to crash.

I know I'm connecting to the correct server and I know the usernames / passwords are correct, I know that the TM1 API is installed correctly on my computer as well.

I've come up with this solution based on dialog between IBM customer support and I.

It requires you add the following declare function:

Declare PtrSafe Function TM1SystemServerConnectWithCAMNamespace Lib "tm1api.dll" (ByVal hPool As Long, ByVal vServerName As Long, ByVal vCAMArr As Long) As Long

The login code:

Dim hArray As Long
Dim lArray(3) As Long

'Login to TM1 using CAM authentication
hArray = TM1ValArray(hPool, lArray(), 3)
TM1ValArraySet hArray, TM1ValString(hPool, "DOMANIN_NAME", 0), 1          
TM1ValArraySet hArray, TM1ValString(hPool, “TM1_USER_NAME”, 0), 2
TM1ValArraySet hArray, TM1ValStringEncrypt(hPool, “TM1_PASSWORD”, 0), 3
hServer = TM1SystemServerConnectWithCAMNamespace( _
    hPool, TM1ValString(hPool, "TM1_SERVER_NAME", 0), hArray)
