Description:

pwdutils is a collection of utilities to manage the passwd and shadow
user information. The difference to the shadow suite is that these
utilities can also modify the information stored in NIS, NIS+, or
LDAP. PAM is used for user authentication and changing the pasword. It
contains passwd, chage, chfn, chsh, and a daemon for changing the
password on a remote machine over a secure SSL connection. The daemon
also uses PAM so that it can change passwords independent of where
they are stored.
