SYNOPSIS

[service-name] module-type control-flag pam_chroot [arguments]

DESCRIPTION

The chroot service module for PAM chroots users into either a predetermined directory or one derived from their home directory. If a user’s home directory as specified in the
.Vt 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.
