ACLs broken on AFP shares

Hello,
I am managing a server (10.6.8) where approximately 30+ users hit AFP on a daily basis. They were using only two shares in their workflow and recently it has been time to add more shares.

I created all the new shares in Server Admin and tested the ACLs. Everything seemed to be fine. (Permissions were propagated accordingly.)

It came up that one user who had Read Only Access on one of the shares needed Read/Write access to a certain Folder (on the root level of this share) and we decided to try it using ACLs. When we added in the ACL for this specific folder, and tested, all ACL’s on the entire server and shares are disregarded.

For instance, a user that has Read Only access to any share, now has Read/Write access to any share, regardless of ACLs. Server has been imaged, all software updates made, and restarted.

Any ideas?

Thanks
