While trying to access some files on my Kubuntu computer from Mac OS X through samba, I ran into the problem that the password I set in the Kubuntu’s system settings for network sharing was denied. It turned out that it wasn’t even accessible through smbclient from the machine itself, and it resulted in a NT_STATUS_ACCESS_DENIED error. The fix was actually quite simple and probably the result of lazy reading when I was setting up the samba server. Read on if you’ve got the same problems.
