Hi All,
I want to know which file system has ACLs that is closer to NT ACLs and more than POSIX ACLs.

Would you elaborate on your exact requirements, please?

I want to know if there is a file system that supports more than rwx for ugo. POSIX ACLs are no different from traditonal unix perms except taht we can have named users/groups apart from owning user/group. They are fundementally the same in terms of meaning of the r,w and x bits. But NT is not like that. I want to know if there any file system that has permissions where we can have dpo bits similar to NT.

As far as I know, Linux ACLs do not implement D(elete), P(rivileges) or O(wnership) bits.

Actually linux does support the above through extended POSIX

Ah!

Would you kindly elaborate on this, and perhaps give us some specific references?

kernel 2.4 needs patching, 2.6 is o.k. for ext2, ext3, jfs, xfs. I don't know about reiserFS. I am using XFS (faster than RFS 3.5 and more reliable than RFS 4).

SuSE is basically ready to go. I assume that RH/Fedora are ready too. I don't know about other distros.

search google for extended POSIX if you need more information. Novell link explains application of extended POSIX.

I hope that this will help
