CAUTION Changing the attribute used to logon could have the unintended effect of preventing the CE system user from being able to logon, thereby preventing Content Engine from being able to launch. If you change the User Search Filter or User Short Name attributes, you must edit the bootstrap file and change the value of com.filenet.gcd.Username
so logon can continue. See CE Bootstrap properties for more information.
