Applying ACLs to SMB Kicks Everyone Out!

Hi everyone, hoping for some ideas or assistance. Brand new Leopard 10.5.4 Xserve, sharing via SMB.

Every time I add or make modifications to the ACLs on a File Share, and I hit the Save button (lower right corner of the Server Admin), everyone of my SMB users gets kicked off the file server. It’s almost like hitting the “Save” button tells it to “restart the SMB service”.

Extremely frustrating as we are currently trying to resolve ACL issues on a few files, and yet we can’t make any changes without booting everyone out of their shares and their files.

Any ideas on what we can do to fix this behavior?! It’s maddening, and our 10.5.4 Server experiences have been consistently less than stellar since we did a fresh install over the 4th of July weekend.

Also, if anyone is interested in our OD/AD/Leopard client to 10.4.11 Server upgrade nightmare, I’ll be happy to post the results of our 100+ hours worth of screwing around to get it to work.
