NAME
pam_chroot -- Chroot PAM module
SYNOPSIS
[service-name] module-type control-flag pam_chroot [arguments]
DESCRIPTION
The chroot service module for PAM chroots users into either a predeter-
mined directory or one derived from their home directory. If a user's
home directory as specified in the passwd structure returned by
getpwnam(3) contains the string ``/./'', the portion of the directory
name to the left of that string is used as the chroot directory, and the
portion to the right will be the current working directory inside the
chroot tree. Otherwise, the directories specified by the dir and cwd
options (see below) are used.
also_root Do not hold user ID 0 exempt from the chroot requirement.
always Report a failure if a chroot directory could not be derived
from the user's home directory, and the dir option was not
specified.
cwd=directory
Specify the directory to chdir(2) into after a successful
chroot(2) call.
dir=directory
Specify the chroot directory to use if one could not be
derived from the user's home directory.
