Subject: [PATCH 1/2] gssapi: assume that mechanism from acceptor credential is
 Kerberos when environment variable GSSAPI_ASSUME_MECH_MATCH is set

The patch allows legacy applications (e.g. SAP Netweaver) to remain compatible
with newer Kerberos. System administrators who are experiencing this
kind of compatibility issues may set environment variable GSSAPI_ASSUME_MECH_MATCH
to a non-empty value, and make sure the environment variable is visible and effecvtive
to SAP Netweaver startup script.

There is no need to send the patch to upstream.
