it's O/S user id and password

Correct so far (for version 7).

In version 8 the user name and password are passed to the login/security service (exposed by WebSphere Application Server) which authenticates against one of:
(a) the internal user registry in the unified metadata repository
(b) the operating system user registry in the engine tier
(c) an LDAP-compliant user registry such as Active Directory

There's more to it - you need to read about shared registries (between services and engine tiers) and DataStage credentials, but the above answers the question that you asked.

Hi All,

In version 8.x authentication is set through WebSphere application Server (WAS) and is used to authentication and security. There are three authentication registries:

- Internal registry(default optin during installation), users and passwords are encrypted in Metadata Repository(DB2 by default).

- Operating System.

- LDAP

Note that Information Server Role/Group assigments and other user metadata are always mantained in the metadata repository.
