Hello, I recently upgraded my server from samba 2.2 to Samba 3.0.14a. Samba is running as PDC. Now i got a strange thing when someone tries to access a share for which (s)he is not authorised, a popup box shows up on the W2K client asking for name and password again, while this used to be a popup box with the announcement that the user is not authorised to access the share. Why is this popup box showing up now? Im using tdbsam as backend, security = user and for example a share defined as: [system] comment = System Config Files path = /etc invalid users = @users write list = @admin read only = No users in the unix group users get the popup box.
