DEPENDENCIES
Pluggable Authentication Modules (PAM)
PAM is an Open Group standard for user authentication, password modification, and account validation. In
particular, pam_chauthtok()
is invoked to perform all functions related to passwd
. This includes
establishing and changing a password, using
passwd
options, and displaying error messages.
WARNINGS
Avoid password characters which have special meaning to the tty driver, such as # (erase) and @ (kill). You
may not be able to login with these characters.
Multiple superusers are allowed, but are strongly discouraged. That is because the system often stores
user ID rather than user name. Having unique IDs for all users will guarantee a consistent mapping
between user name and user ID.
FILES
/etc/passwd Standard password file used by HP-UX.
/etc/shadow Shadow password file (requires the ShadowPassword
bundle).
/tcb/files/auth/*/*
Protected password database used when system is converted to trusted sys-
tem.
/etc/nsswitch.conf

/etc/default/security
