Hi all,

is there any recomended ACL setting for user homedirs?

I'de like to do following:

- users are owners of their homedirs (we use owner-based quotas)
- users cannot change permissions of their homedirs

Is that possible?

However, ownership seems to override even "deny change permissions" ACL. Is
there any other way to deny access for the user to the other homedirs?

Thanks,

I believe it is a grant of Full Control for the account, optionally
also a grant to Administrators, and nothing else.

No, not directly on any Windows client OS released to date.
There is one work around that may sometimes be of use.
Since share level permissions set the upper bound on what may
be used of the NTFS permissions when access is via a share,
if an account has Full at NTFS level but the share level permissions
are only Change, then it is not possible to use the ability to change
permissions when the access is via the share.

That is correct, it does do so.

Not sure what this asks, "other homedirs"? Just do not give
the account any grant on the other homedirs, only on their own.

Ownership is very descriptive name. Owner is the one who can reset any ACL.
