AltLinux Server 4.0 + Samba-3.0.25
When joined to a Samba PDC, the XP x86_32 machine exhibits the following behavior:
Select a folder, go to security options and hit 'add' to add a
user. This brings up a dialog which reads:
"The program cannot open the required dialog box because it cannot
determine whether the computer named "server" is joined to a domain. Close
this message, and try again."
After which you see:
"Unable to display the user selection dialog. This action is only
valid for products that are currently installed."
