It did not work.
Have you read the official samba documentation? The Samba-HOWTO-Collection has an entire chapter that is dedicated to explanation of how file, directory and share access permissions operate. Check: http://www.samba.org/samba/docs/Samba-HOWTO-Collection What you want does not require the nuclear strong-arm tactics you have attempted in the [docs] stanza, but can be achieved simply by setting the SGID bit on the /samba/docs directory, setting the group ownership of that same directory to the group who should own the files within it, and then setting the group read and write permission as you require. eg: chown samba.info /samba/docs chmod u=rwx,g=rwxs,o-rwx /samba/docs A stanza that can be used is: [docs] path = /samba/docs read only = no ; The following is better handled by setting a share level ACL so that ; only the group 'info' can access the share. That has lower CUP overhead ' but if you do not set a share ACL the 'valid users' parameter comes in handy valid users = @info - John T. > > > How can I avoid group owner modifications? > > > Any help would be appreciated. > > > Zoltan Sutto -- John H Terpstra Samba-Team Member Phone: +1 (650) 580-8668 Author: The Official Samba-3 HOWTO & Reference Guide, ISBN: 0131453556 Samba-3 by Example, ISBN: 0131472216 Hardening Linux, ISBN: 0072254971 Other books in production. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
