NAME
pam_unix_account - PAM account management module for UNIX
SYNOPSIS

locked or expired and that the user's password does not need to be
changed. The module retrieves account information from the configured
databases in
nsswitch.conf(5).
The following options can be passed to the module:
debug syslog(3C) debugging information at the
LOG_DEBUG level

server_policy If the account authority for the user, as specified
by
PAM_USER, is a server, do not apply the Unix
policy from the passwd entry in the name service
switch.
