I'm not able to change the username/password for my eDir user source.
Initially I used the admin account just to be sure we didn't run in to any
rights issues. Now I want to use a read-only user. But when I enter the new
username and password in Control Center, the old admin account remains
unchanged. It does check the new username/password, because it doesn't get
accepted when I use a wrong password.

Running ZCM 10.3.2.

Any ideas?
