Using qws server in multi-app multi-user environment ....

[Momo3000]

Hello,

I am trying to devise an application architecture on ARM-9/Linux based board that will allow single Qt embedded (4.8.3) server application to accept connections from number of Qt client applications, each running as a separate user.
I tried running server app (-qws) as root and connecting client app owned by valid Linux user "guest". That failed on access to the control socket.

Server creates AP/PF_UNIX socket and sets SO_PASSCRED option to "true" on that control socket. I guess that means that client application must authenticate itself to the server on startup using ancillary message (SCM_CREDENTIALS).

If that is the case, how do I do that using existing, legitimate Qt features/options (rather then trying to hack Qt source tree)?
Is this even possible? If not, what are the alternatives?

Thanks in advance for any help that might be coming ....
