s3-librpc Call GSSAPI via the auth_generic layer and gensec
This simplifies a lot of code, as we know we are always dealing with a struct gensec_security, and allows the gensec module being used to implement GSSAPI to be swapped when required for AD-server operation. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
