[Samba] group permissions broken after upgrade 3.2.5 -> 3.4.8: deleting of files denied

[Christian PERRIER]

Quoting Marc Schiffbauer (marc at schiffbauer.net):

> Now after the upgrade delete operations on files do not work anymore 
> until a user owns the parent directory or has world write access to
> it (windows client (XP SP2) gets a permission denied error).
> 
> This is strange because a user can still create files within a dir
> that he does not own, so this can only be permitted by group permission, 
> but deleting the same file gives a permission denied.
> 
> What might cause this? Is this a known bug in samba 3.4.8?


How about looking in log files, preferrably after raising the log
level to 3?
