[Bug 21397] New: LookupAccountName cannot retrieve a 'groups' SID

http://bugs.winehq.org/show_bug.cgi?id=21397

Summary: LookupAccountName cannot retrieve a 'groups' SID
           Product: Wine
           Version: 1.1.36
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: advapi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Debugging an application I found the cause of the first failure is that the
software installs a 'group' (which fails with a fixme). Post install, I created
a group (addgroup) but the application calls LookupAccountName to retrieve the
SID of that created group.

You can hack around this (if LookupAccountName fails, query the current user
and re-call the function to get it's sid) but looking at the function there is
complete support missing for anything other than the current user.

Ideally it should call (something like getgrent?) and if it finds a group, map
it to a SID somehow (perhaps end the SID with the gid?). It could handle
querying other users as well in a similar way (getpwnam?)
