I have read (I suppose) all of the documentation about Samba, but I have not found a detailed description of the contents of the various tdb files. It should be useful to know what information goes in each file, and eventually which file can be safely deleted and rebuilt. For example, I have discovered by myself that group mapping could be reset and re-done by simply deleting the appropriate tdb file, but still I was not sure if this could lead to hidden issues before I have read John Terpstra's mail on this list suggesting to delete the tdb file and then to re-run the group mapping script. -- Fabio "Kurgan" Muzzi
