In some cases, a system other than eDirectory might contain the users that you want to participate with the driver. There are tools, such as LDIF, that you can use to import these users into eDirectory.
If you cannot extract the passwords for the affected user accounts, you can use the driver Password Migration component. This component can help you accomplish a smooth transition to basing your user accounts in eDirectory. The Password Migration component is available only on z/OS platforms. For details about the Password Migration component, see the Identity Manager Fan-Out Driver for Mainframes Administration Guide.
