The tcb suite implements the alternative password
shadowing scheme on Openwall GNU/*/Linux (Owl)
which allows many core system utilities (passwd(1)
being the primary example) to operate with little
privilege. It is being made available separately
from Owl primarily for use by other distributions.
This package contains three core components of the
tcb suite: pam_tcb (a PAM module which supersedes
pam_unix), libnss_tcb (the accompanying NSS
module), and libtcb (a library for accessing tcb
shadow files, used by the PAM and NSS modules as
well as by user management tools on Owl).
