I have security=share and I think it is the perfect solution. Windows clients can browse all public shares just fine and you get prompted for a password when trying to browse a private share. In Linux it doesn't work, here is what happens even when you enter a valid username and password: Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.28-0.el4.9] Server not using user level security and no password supplied. Server requested LANMAN password (share-level security) but 'client lanman auth' is disabled tree connect failed: SUCCESS - 0 It seems that you can't authenticate with the client when you have security=share. Does anyone have a solution? Thanks
