As Debian bug #352313 clearly shows, users "blindly" using options such as "socket address" are shooting themselves in the foot. So, I suggest that the smb.conf manpage explicitly discourages its use. Proposed patch attached.
Created attachment 3785 [details] Patch fdor the smb.conf.5 manpage Proposed patch
Should be fixed with 19beef0dd. Will be in the next releases. I added "Setting this option should never be necessary on usual Samba servers running only one nmbd" to keep it more general. Closing out bug report. Please re-open if it is still an issue for you. Thanks for reporting!
