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. -------------------------------------------------------------------------------- Update Information: CVE-2015-1827: It was discovered that the IPA extdom Directory Server plug-in did not correctly perform memory reallocation when handling user account information.
