I have a "webfarm", of 15 web server machines.
I want to have a single location in which to manage my users and groups.
How can I protect directories
on each machine from a single location?
When you update the directory protections (adding a new directory), then make the changes in both .adb files on both machines. If you make a lot of complex changes, then you can copy the adb file from one machine to another, as here.
