21.3 NIS+

21.3.4 Authorization and Authentication

NIS+ authorization allows four classes of principals:

Authentication is based on secure RPC. Solaris 2 supports three levels:

DES authentication is the most secure, but if you are running with Secure RPC you will not be able to mount files from servers not running Secure RPC (i.e. SunOS 4.X servers).

Authentication is performed for every NIS+ request. If credentials can not be confirmed the client is treated as nobody.
