[SSSD] [PATCH] fix GSSAPI integrity detection for AD servers

[Simo Sorce]

This patch (hopefully) fixes an interop issues with AD servers where
they fail to realize the connection is indeed integrity protected.

It's a bit of a hack as we need to work around openldap initialization
of cyrus sasl libraries. But it should work unitl we get openldap
libraries to expose SASL_CB_GETOPT to us.
