NIS Plug-ins in Identity Management
- NIS Server Plug-in
- The NIS Server plug-in enables the IdM-integrated LDAP server to act as a NIS server for clients. In this role, Directory Server dynamically generates and updates NIS maps according to the configuration. Using the plug-in, IdM serves clients using the NIS protocol as an NIS server.For further details, see Section 21.2, “Enabling NIS in Identity Management”.
- Schema Compatibility Plug-in
- The Schema Compatibility plug-in enables the Directory Server back end to provide an alternate view of entries stored in part of the directory information tree (DIT). This includes adding, dropping, or renaming attribute values, and optionally retrieving values for attributes from multiple entries in the tree.For further details, see the
