When I call AcquireCredentialsHandle() I could specify
fCredentialUse be Inbound, Outbound or Both.

If I want to use the same credential for both outbound(client) and
inbound(server). But in MSDN it says:
 SECPKG_CRED_BOTH - Validate an incoming credential or use a local
credential to prepare an outgoing token. This flag enables both other flags.
This flag is not valid with the Digest and Schannel SSPs.

I'm using Schannel SSP. what should I use in this case?

Thanks,

Sherry
