[Bug 10612] New: LookupAccountNameA returns Domain Size that is one byte too big

http://bugs.winehq.org/show_bug.cgi?id=10612

Summary: LookupAccountNameA returns Domain Size that is one byte
                    too big
           Product: Wine
           Version: 0.9.49.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-advapi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

When calling LookupAccountNameA in Windows, cbReferencedDomainName is set to
the number of characters in the string (e.g. for "DOMAIN" windows returns 6).
In my tests Wine always returned the string "DOMAIN" and the length 7.

I think the bug is in there because LookupAccountNameW is called internally but
that function is supposed to return the number of characters plus 1.

I confirmed the behaviour in Vista and Windows 2000.

I will try to fix it myself.
