ProcedureHow to Set Up a Diffie-Hellman Key for an NIS User

This procedure should be done for every user in the NIS domain.

Before You Begin

Only system administrators, when logged in to the NIS master server, can generate a new key for a user.

  1. Assume the Primary Administrator role, or become superuser.

    The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.

  2. Create a new key for a user.

    # newkey -u username

    where username is the name of the user. The system prompts for a password. You can type a generic password. The private key is stored in an encrypted form by using the generic password.

  3. Tell the user to log in and type the chkey -p command.

    This command allows users to re-encrypt their private keys with a password known only to the user.

    Note –

    The chkey command can be used to create a new key pair for a user.
