samba - Apr 2006 - File Permissions

Hello

I trying to grasp the file permissions on Linux.  I have Samba installed
and functioning properly...

I think I understand perimission in this environment with one exception:
I need to add more than one group to a file/folder.  With Windows..the
security tab would allow any number of Groups and each group could have
different permissions.  (As well with files and subdirectories).  With
Linux Im not "seeing" this ability to add multiple groups to a
file/folder.  Is this a limitation to the Linux environment?  We have
several situations where we allow a user to "List Content" but down
into
the folder structure allow the user to Read some folders and others
Read/Write. 

Thanks

Regards,

Komal

Hi,
You must use ACL's.
Your Kernel+FileSystem must suport it and samba must have been compiled with
acl support.
But just one personnal remark, the path you're trying to walk (many
different permissions at different directory levels) is a dangerous one.
Trust me.
I've been there, done that, and fortunely fled away from it.

Hi,
The main problem was when trying to manage different permissions at
different levels, it became really messy. I just lost too much time managing
almost every directory one by one.
So now I've managed to take a different approach. To every directory
there's
only two types of access. One group with rwx and another with rx. This
permissions are set via ACL at first level. On the following levels every
file has 775 permissions.
Very easy to maintain... But the fact that it works for, doesn't mean it
will work for you.
