How to Specify a New Password Algorithm for an NIS Domain

  1. Specify the password encryption algorithm in the /etc/security/policy.conf file on the NIS client.

  2. Copy the modified /etc/security/policy.conf file to every client machine in the NIS domain.

  3. To minimize confusion, copy the modified /etc/security/policy.conf file to the NIS root server and to the slave servers.

When users in an NIS domain change their passwords, the NIS client consults its local algorithms configuration in the /etc/security/policy.conf file. The NIS client machine encrypts the password.
