[Bug 1643708] Please test proposed package

[Bruce Campbell]

I set up yakkety with the proposed packages and built omi, and connected
propertly with win10 encrypted. This had been failing.

The patch appears to work.

Bug description:
  [Impact]
  MS-SPNG section 3.3.5.1 documents an odd behavior the SPNEGO layer
  needs to implement specifically for the NTLMSSP mechanism.  This is
  required for compatibility with Windows services.

  Upstream commit:
  https://github.com/krb5/krb5/commit/cb96ca52a3354e5a0ea52e12495ff375de54f9b7

  We've run into this issue with Linux to Windows negotiation with
  encrypted http using GSSAPI.

  [Test Case]

  create a file with some credentials:

  $ echo F23:guest:guest > ~/ntlmcreds.txt
  $ export NTLM_USER_FILE=~/ntlmcreds.txt
  $ python
  import gssapi

  spnego = gssapi.raw.oids.OID.from_int_seq('1.3.6.1.5.5.2')
  c = gssapi.creds.Credentials(mechs=[spnego], usage='initiate')
  tname = gssapi.raw.names.import_name("F23/server", name_type=gssapi.raw.types.NameType.hostbased_service)
  ac = gssapi.creds.Credentials(mechs=[spnego], usage='accept')

  seci = gssapi.SecurityContext(creds=c, name=tname, mech=spnego, usage='initiate')
  seca = gssapi.SecurityContext(creds=ac, usage='accept')
  it = seci.step(token=None)
  ot = seca.step(token=it)
  it = seci.step(token=ot)
  ot = seca.step(token=it)
  it = seci.step(token=ot)

  e = seci.wrap("Secrets", True)
  o = seca.unwrap(e.message)

  o.message
  'Secrets'
