DCE/RPC GSSAPI

[SaNtosh kuLkarni]

Does DCE/RPC support GSS-Negotiation with a MSRPC based RPC server?
I am trying to develop a DCE-RPC based client(linux ) which talks to a
MSRPC based server running on Windows.

I configured the DCE/RPC build     with --enable gss-negotiate.

The security nego flow on the linux rpc client is as follows

 unsigned32 authn_protocol = rpc_c_authn_gss_negotiate;
 unsigned32 authn_level = rpc_c_authn_level_pkt_privacy;

  rpc_binding_set_auth_info (xxxx_IfHandle, (unsigned_char_p_t)principal,
                        authn_level,
                        authn_protocol,NULL,
                        rpc_c_authz_name, &st);
        if (st != rpc_s_ok) {
                dce_error_inq_text(st, error_text, &error_inq_st);
                fprintf(stderr, "Cannot set security authorization for
server %s: %s\n", entry_name, error_text);
        }

Is there anything else that needs to be done.I have developed a similar
windows client which works fine.But when i use the same security api
 coding flow and set the protocol and auth level it fails on linux with the
following

I would be grateful if anyone could guide me on this.Thanks!
