What are the key differences between NIS and NIS+?
There are many differences, but the main four are: – NIS had a flat name space, while NIS+ is hierarchical. With NIS+, growth and changes can be easily managed. – NIS+ is secure and allows fine grain access control. – NIS+ updates are on incremental basis and much faster (in minutes). – NIS tables were single key-value pairs while NIS+ has multiple key value pairs. This means that you can do searches based upon a particular value of a particular key.
