Linux – Mount cifs share anonymously

This might be completely off, but do the XP clients have simple file sharing enabled? And are they XP pro or home?

To check on simple file sharing:

1. Open an explorer window
2. Click Tools, Folder Options
3. At the bottom of the list is the checkbox for simple filesharing.

You would probably need to use the username map functionality inside samba (winbind) for the mapping to work so that winbind knows about the AD account for every Linux user. I believe username map can take commands and lists (and some pattern conversions), but it's far easier if the Linux usernames can match the AD usernames, by using pam_winbind for instance. I guess that when the mapping is working you can actually start verifying whether the share is working as well.
