pam_unix_account - PAM account management module for UNIX
SYNOPSIS

DESCRIPTION
pam_unix_account module implements pam_sm_acct_mgmt(), which provides
functionality to the PAM account management stack. The module provides
functions to validate that the user's account is not 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 nss‐
witch.conf(4).
The following options can be passed to the module:
debug
syslog(3C) debugging information at the LOG_DEBUG

from the passwd entry in the name service switch.
