PAM_CHROOT(8)			   BSD 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 predetermined 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 directo-
     ries 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.
