NIS to LDAP Migration using Penrose

With NIS is being EOL’d by Sun, most organizations will want to migrate their NIS servers to LDAP-based directories. Organization who is still using Sun NIS will fail Sarbanes-Oxley audits. However, the Sun current migration process is fairly lengthy and complicated one. Penrose can simplify this process by providing an LDAP façade for the NIS backend servers. Its NIS adapter technology will facilitate an extended transition period by leveraging data in the NIS domains data stores. Its transformation, join and proxy engines will help address data migration concerns such as UIDs and GIDs conflicts (non unique across all of its NIS domains) and management of site local data. The advantage of this approach is that administrator can start moving pool of machines into the new LDAP system in a staggered manner with no or minimal downtime.
