Enhancements have been made to the name service switch (nss) and to the Name Switch Cache Daemon (nscd(1M)) in order to deliver new functionality. These enhancements include the following:
Better caching in nscd(1M) and management of connections within the updated framework
Name service lookups that are access controlled at the naming service on a per-user basis. The updated switch framework adds support for this style of lookups using SASL/GSS/Kerberos in a manner that is compatible with the authentication model used in the Microsoft Active Directory.
A framework for the future addition of putXbyY interfaces.
For more information about per-user lookups, see System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP).
