User registry configuration

A user registry holds user account information, such as a user name and password, that is accessed during authentication. To log in to IBM® InfoSphere® Information Server, a user must have a user name and password in the user registry.

During installation, the InfoSphere Information Server installation program configures InfoSphere Information Server to use an internal user registry. The internal user registry is located in the metadata repository. After you install InfoSphere Information Server, you can continue to use the internal user registry. Alternatively, you can set up InfoSphere Information Server to use a local operating system user registry or a Lightweight Directory Access Protocol (LDAP) compliant user registry.

If you choose to change registries, complete the change immediately after the installation finishes. For best results, do not change user registries after the system has been in production. If you must change the user registry after the system has been in production, consider migrating to a new installation to avoid security issues and risks. Otherwise, a mismatch might occur between the users of the old and new user registries.
