Re: Patch For sspi.c To Use Windows Authentication

Yes, I think your connection is using Kerberos. We have similar code
even for gssapi (that provide Kerberos for the Unix world). It must be
return tds_flush_packet(tds), not return status. Also you miss a
CompleteAuthToken call on SEC_I_COMPLETE_AND_CONTINUE.
