Samba problem with user level share permissions under Windoze

[Andrew Pollock <andrew@andrew.net.au>]

Hi,

I'm trying to configure a Windoze 98 PC on my home network to use user level
share permissions instead of share level permissions, and when I go to add users
to a particular share, Windows barfs:

You cannot view the list of users at this time. Please try again.

and I get:

[2001/09/03 14:21:29, 1] smbd/ipc.c:api_fd_reply(3314)
  api_fd_reply: INVALID PIPE HANDLE: 0
[2001/09/03 14:21:29, 1] smbd/ipc.c:api_fd_reply(3314)
  api_fd_reply: INVALID PIPE HANDLE: 0
[2001/09/03 14:24:15, 1] smbd/service.c:close_cnum(583)

in /var/log/smb

I haven't been able to find any mention of this in the Samba FAQ, and nothing
overly useful with Google. Microsoft Knowledge Base article Q177607 refers to
something related to Outlook Express, but I'm not sure if it affects me or
not.

Has anyone else been there, done that?
