+# a users home directory when they log in if it doesn't already exist.
+# Because `hackers.git` doesn't store any password information, `nshd`
+# stores password hashes in `/etc/nshd/shadow`.

+# Sometimes after something fails in PAM, you get a "User not known to
+# the underlying authentication module" message.  For exaple, the
+# `pam_ldap.so.2` failed because you typed your password wrong, but
+# the PAM caller thinks `pam_ldap` failed because it didn't "own" the
+# user.  I think that it's just a bug in PAM's message selection.  But
+# (TODO) we should actually track it down.
