Recently some folks in our engineering group started encountering a
problem where they can't write to or alter files or folders they did not
create.
Anyone know what could be causing this type of problem? The users having
the problem are all in the eng group is /etc/groups. smb.conf for that
share:
smb.conf:
#smb.conf is the main Samba configuration file. You find a full commented
# version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the
# samba-doc package is installed.

Best thing is to log a bug containing a level 20 log file of the permission denied problem. Jeremy.

I've never used the acl commands before, we didn't know they existed, we've been attacking the problem from a linux permissions standpoint. getfacl returns for the parent folder # file: data/engineering/beta/Builds # owner: hankj # group: eng user::rwx group::rwx other::r-x and for the folder in question: # file: Mac # owner: jimd # group: eng user::rwx group::rwx other::r-x How do I delete these acls with the setfacl command? trying to figure out syntax, but not getting anywhere. - Joel
