SAMBA/LINUX

Nobody's Hero — Mon, 10 May 2004 10:53:19 GMT

Hi All,

I have successfully setup SAMBA 2.2.8a on Redhat Linux9. We use this for our production system/share for the NT side of the house. We share out the files through linux and mount them on the users desktop via NT. All permissions for the shares are controlled through the NT side/win2k. Here is my problem.

I made a change to one of my shares. The change I made was 'force user = psoft'. Well the way we have things set up, this opened the door for all directories under this share. Users that have access to the top level share 'hrprd', now have rwx to all folders under this share. Well, I removed the force user entry. Then I run a 'getfacl hrprd' and it all looks ok. Somehow samba is still holding the change I made, allowing all users to access folders under this specific share. All other shares are working fine. Only this share is messed up after I madt the force user change. Is there a way that samba holds the acl entries in a database or something? Is there something I can flush in an ACL database?

by running testparm utility on samba config file you can see the settings that are in a file and if you restart the samba service they will be applied.
So if samba's config file is /etc/samba/smb.conf:
testparm /etc/samba/smb.conf |less

What are other settings for this share?

Is there some sort of ACL database file that can be cleaned up? All my settings are OK. This system has been in production for over a year.

Re: SAMBA/LINUX

Is there a way I can restore the previous ACL entries for this Dir using setfacl ?

have you tried restarting samba?

Yes, but thanks. Way beyond that.

Some thoughts

If a user has rwx share level access to a top level folder this will be applied to files and folders underneath this folder unless the File system permissions for each object underneth are more restrictive.

If there are folders which are shared underneath this folder, the shared permissions for these folders will not apply if the user gains access via the top level share.

Have you checked actual file ownership and permissions have not changed at file system level ??

hi,

your linux file-system should support ACL ! like XFS (for example)
