commit 449ab398f58c6e0041621752322ebe24e6d70225

    s3-spnego: Fix Bug #6815. Windows 2008 R2 SPNEGO negTokenTarg parsing 
failure.
    
    When parsing a SPNEGO session setup retry (falling back from KRB5 to 
NTLMSSP),
    we failed to parse the ASN1_ENUMERATED negResult in the negTokenTarg, thus
    failing spnego_parse_auth() completely.
    
    By just using the shared spnego/asn1 code, we get the parsing the correct 
way.
