Windows runas /netonly equivalent or implementation?

hello all,

first, i'm not quite sure which forum is best fit for this thread. so if an LQ admin wishes to move this thread to a more appropriate forum, please do.

intro: Windows "runas /netonly" is able to authenticate to local resources as yourself (the logged-on user), but authenticate to network resources as another user.

as i understand, sudo authenticates to both local and network resources as another user.

how does one implement split authentication in Linux?

thanks for any hints.

ERRRGH! i wrote a full 4-paragraph answer, and when i clicked "Submit" the forum kicked me out! said i wasn't logged-in!

so i'll be very brief now:
Windows legacy app. no networking. stores sensitive data on a file server (SMB share, no matter what platform). no server-side. data is accessed only when network share is mounted.
PROBLEM: user has direct access to data.
SOLUTION (under Windows): runas /netonly with user account that has access to the file server.

i'm asked to port the application to Linux clients. app running OK under Wine. Wine must have the volume mounted => same problem. Wine has no independent networking capabilities => solution does not apply.

hope this explains better, feel free to ask further. any suggestions or leads are welcome.

investigating further, i just stumbled upon AppArmor. quote from it's description at the Wiki:

"AppArmor security policies completely define what system resources individual applications can access, and with what privileges."

sounds like it's just what i need, but... i need it to enforce a "allow" policy for a specific Wine application, not the Wine launcher itself; while enforce a "deny" policy for anything else, including the user; and the system resource in question is on network, not local.

AppArmor users/gurus, are you there? can AppArmor do it?
