Updating an OperatorID record can be bypassed during authentication by setting the extAssignFlag property with any non-blank value. This flag is ignored during Authentication.unauthenticate() method. However, it still respected and the update is skipped during initializeUser() method. The save that occurs during unauthenticate() should fall under the same conditions. This is a performance issue that introduces contention for services which utilize a single OperatorID because threads compete for updates to the common row.
