<div dir="ltr"><div style>Hi,</div><div style><br></div><div style>I am trying to develop a DCE-RPC based client which talks to a MSRPC based server running on Windows.</div><div style><br></div><div style>I configured the DCE/RPC build with --enable gss-negotiate.<br>
</div><div style><br></div><div style>The security nego flow on the linux rpc client is as follows</div><div style><br></div><div style><div> unsigned32 authn_protocol = rpc_c_authn_gss_negotiate;</div><div> unsigned32 authn_level = rpc_c_authn_level_pkt_privacy;</div>
<div><br></div><div><div> rpc_binding_set_auth_info (hello_IfHandle, (unsigned_char_p_t)principal,</div><div> authn_level,</div><div> authn_protocol,NULL,</div><div> rpc_c_authz_name, &st);</div>
<div> if (st != rpc_s_ok) {</div><div> dce_error_inq_text(st, error_text, &error_inq_st);</div><div> fprintf(stderr, "Cannot set security authorization for server %s: %s\n", entry_name, error_text);</div>
<div> }</div></div><div><br></div><div style>Is there anything else that need to be done.I have developed a similar windows client which works fine.But when i do the same security api flow and set the protocol and auth level it fails on linux with the following</div>
