I'm working in a university which has an Active Directory with 12'000 entries. The ACL (Access control list) form shows all users and groups in a 20 lines window with only up and down arrows to find and select entries among the 12’000 entries. It’s really like looking for a needle in a haystack! This form could greatly be improved by providing a search tool.
Permissions given to a folder using ACL are propagated from the OpenE server to Windows. If you change permissions to a folder on the Windows computer which is using the share, the change is not propagated back to the OpenE server (or taken into account by it) and it is like if nothing was done.
Another weird thing with this interface is that you are automatically propagated to the root of the filesystem each time you apply a new permission to a folder bellow. You have then to go down the filesystem to make another change. Imagine doing this for more than 10 users!
