NIS+ credentials are used to identify NIS+ users. This chapter assumes that you have an adequate understanding of the NIS+ security system in general, and in particular of the role that credentials play in that system.
For a complete description of NIS+ credential-related commands and their syntax and options, see the NIS+ man pages.
The description of DES credentials in this chapter is applicable to 192-bit Diffie-Hellman DES credentials. While similar, authentication using other key lengths differs in details. When the command line interface is used to manipulate the keys, the differences are transparent to both the user and the system administrator. Use nisauthconf to display or set the prescribed key lengths.
