How to Specify a New Password Algorithm for an NIS+ Domain
When users in an NIS+ domain change their passwords, the NIS+ name service consults the algorithms configuration in the /etc/security/policy.conf file on the NIS+ master. The NIS+ master, which is running the rpc.nispasswd daemon, creates the encrypted password.
Specify the password encryption algorithm in the /etc/security/policy.conf file on the NIS+ master.
To minimize confusion, copy the NIS+ master's /etc/security/policy.conf file to every host in the NIS+ domain.
