NIS+ Security Levels and Password Commands

In Solaris releases 2.0 through 2.4, you used the nispasswd command to change your password. However, nispasswd could not function without credentials. (In other words, it could not function under security level 0 unless there were credentials existing from some previous higher level.) Starting with the Solaris 2.5 release, the passwd command must be used to change your own password regardless of security level or credential status.
