Windows Server - credential provider: 64 bit anomaly

Asked By dmm

My credential provider was compiled & linked as a 32 bit program.  It
executes without error on vista x32.

I compiled & linked the same source code as a 64 bit program.  It does not
successfully execute on vista x64.  The object's "Advise" function is never
called and the object is unloaded.  A partial trace of the sequence is as
follows:

ENTER CCSampleProvider::GetCredentialCount
EXIT CCSampleProvider::GetCredentialCount
ENTER CCSampleProvider::GetCredentialAt
EXIT CCSampleProvider::GetCredentialAt
ENTER CCSampleProvider::GetFieldDescriptorCount
EXIT CCSampleProvider::GetFieldDescriptorCount
ENTER CCSampleProvider::GetFieldDescriptorAt
EXIT CCSampleProvider::GetFieldDescriptorAt
ENTER CCSampleProvider::GetFieldDescriptorAt
EXIT CCSampleProvider::GetFieldDescriptorAt
ENTER CSampleCredential::GetBitmapValue
EXIT CSampleCredential::GetBitmapValue < hr=0 >
ENTER CSampleCredential::GetFieldState
EXIT CSampleCredential::GetFieldState < hr=0 >
ENTER CSampleCredential::GetStringValue < fieldID=1 >
EXIT CSampleCredential::GetStringValue < str=abc hr=0 >
ENTER CSampleCredential::GetFieldState
EXIT CSampleCredential::GetFieldState < hr=0 >
--- !!! CSampleCredential::Advise should be called at this juncture !!! ---
CP-DLL DllMain.DLL < DLL_PROCESS_DETACH threadID=3d4 >

Any ideas why "Advise" is not invoked?

Thanks
