Subject: About PCAS Access Control

Hi all,
 
Here is my question. I want to add  access control to my PCAS, but I do not  know what the pUserName and pHostName in the following function refer to clearly.
virtual casChannel *createChannel ( const casCtx &ctx,const char * const pUserName,const char * const pHostName);
In "Channel Access Protable Server API Tutorial" it said that points to a string representing the user's name and  pHostName points to a string representing the server tool's host. For example, I have two EDM clients application run on the same linux PC, does the user's name refer to the PC name or something else.
 
I have implemented the createChannel function and  writeAccess function like this:
 
casChannel *exPV::createChannel ( const casCtx &ctx,
        const char * const  /*pUserName*/, 
        const char * const  /*pHostName*/)
{
    return new exChannel ( ctx,"zhangyul","Administrator");
}
///////////////////////////////////////////////////////////////////
bool exChannel::writeAccess () const
{
      if (strcmp(User.string(), "zhangyul") == 0)
return aitFalse;
      else
return aitTrue;
}
 
However, I found that any client could not write the PCAS's PV, I think my understanding is totally wrong about user's name and the host name!!
 
Thank you!
