NAME

6       pam_time - PAM module for time control access
7

SYNOPSIS

9       pam_time.so [conffile=conf-file] [debug] [noaudit]
10

DESCRIPTION

12       The pam_time PAM module does not authenticate the user, but instead it
13       restricts access to a system and or specific applications at various
14       times of the day and on specific days or over various terminal lines.
15       This module can be configured to deny access to (individual) users
16       based on their name, the time of day, the day of week, the service they
17       are applying for and their terminal from which they are making their
18       request.
19
20       By default rules for time/port access are taken from config file
21       /etc/security/time.conf. An alternative file can be specified with the
22       conffile option.
23
24       If Linux PAM is compiled with audit support the module will report when
25       it denies access.
