Does WebSphere Application Server work with NIS?

WebSphere Application Server does not directly support NIS (Network Information Service) for authentication. It supports LDAP, OS, and custom. When running on a UNIX operating system, WebSphere Application Server uses the standard UNIX password APIs (getpw*, and so on) for verifying user password (WebSphere Application Server must run as root for this to work). If those APIs call to NIS, then WebSphere Application Server will use NIS for authentication, but this is transparent to WebSphere Application Server. However, when an OS registry is used on UNIX, then multi-node cells are not supported.
It might be possible to write a custom registry to use NIS.
In most cases, the answer to this question is no.
