Fix SPNEGO one-hop interop against old IIS
|
|
|
|
IIS 6.0 and similar return a zero length reponse buffer in the last
|
|
SPNEGO packet when context initiation is performed without mutual
|
|
authentication. In this case the underlying Kerberos mechanism has
|
|
already completed successfully on the first invocation, and SPNEGO
|
|
does not expect a mech response token in the answer. If we get an
|
|
empty mech response token when the mech is complete during
|
|
negotiation, ignore it.
