Get Username string from RPC binding handle
To retrieve the username string from an RPC (Remote Procedure Call) binding handle in C++, you can use the RpcBindingInqAuthClient
function. This function allows you to obtain the security context information associated with the RPC binding handle, including the username. Here's an example:
cpp#include <rpc.h>
#include <rpcdce.h>
#include <iostream>
int main()
{
RPC_BINDING_HANDLE bindingHandle; // Your RPC binding handle
RPC_SECURITY_QOS securityQos;
RPC_STATUS status = RpcBindingInqAuthClient(bindingHandle, nullptr, &securityQos, nullptr, nullptr, nullptr);
if (status == RPC_S_OK)
{
RPC_AUTHZ_HANDLE authzHandle;
unsigned char* username;
status = RpcImpersonateClient(bindingHandle);
if (status == RPC_S_OK)
{
status = RpcBindingInqAuthClient(bindingHandle, &authzHandle, nullptr, &username, nullptr, nullptr);
RpcRevertToSelfEx(bindingHandle);
if (status == RPC_S_OK)
{
std::cout << "Username: " << username << std::endl;
RpcStringFree(&username);
}
}
}
return 0;
}
Make sure to replace bindingHandle
with your actual RPC binding handle. The RpcBindingInqAuthClient
function retrieves the security context associated with the binding handle. By impersonating the client using RpcImpersonateClient
, you can access the username using RpcBindingInqAuthClient
with the username
parameter.
Note that this code assumes you're working with Windows RPC and using the appropriate headers (rpc.h
and rpcdce.h
). Additionally, handle error checking and appropriate error handling based on your application's requirements.
By utilizing the RpcBindingInqAuthClient
function and related RPC functions, you can retrieve the username string from an RPC binding handle in C++.
