NTLM Server CompleteNeeded being returned after Authentication message

[jborean93]

The NTLM acceptor is returning CompleteNeeded after processing the authentication message from the initiator

sspi-rs/src/ntlm/messages/server/authenticate.rs

Line 52 in 1f71235

Ok(crate::SecurityStatus::CompleteNeeded)

This is different from SSPI actual which just returned SEC_E_OK. It seems like CompleteAuthToken has been implemented to finalise the security context but this should just work like SSPI actual and be done when processing the authentication message

sspi-rs/src/ntlm/messages/server/complete_authenticate.rs

Line 7 in 1f71235

pub fn complete_authenticate(context: &mut Ntlm) -> crate::Result<SecurityStatus> {

The CompleteAuthToken notes even states it is only for the Digest sec provider

This function is supported only by the Digest security support provider (SSP).
