slapi-nis binary package in Ubuntu Bionic s390x

 This package provides two plugins for Red Hat and 389 Directory Server.
 .
 The NIS Server plugin allows the directory server to act as a NIS server
 for clients, dynamically generating and updating NIS maps according to
 its configuration and the contents of the DIT, and serving the results to
 clients using the NIS protocol as if it were an ordinary NIS server.
 .
 The Schema Compatibility plugin allows the directory server to provide an
 alternate view of entries stored in part of the DIT, optionally adding,
 dropping, or renaming attribute values, and optionally retrieving values
 for attributes from multiple entries in the tree.
