PAM_CHROOT(8)           NetBSD System Manager's Manual           PAM_CHROOT(8)


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.
