a2d20838b0 Move the code from pam_sm_authenticate() to pam_sm_acct_mgmt(). Simplify 
it a little and try to make it more resilient to various possible failure
conditions.  Change the man page accordingly, and take advantage of this
opportunity to simplify its language.

f748a713da PAM modules shouldn't call putenv(); pam_putenv() is sufficient. The 
caller is supposed to check the PAM envlist and export the variables it
contains; if it doesn't, it's broken.

9201dc40bf Change the order in which pam_sm_open_session() updates the logs. This 
doesn't really make any difference, except it matches wtmp(5) better.

Don't do anything in pam_sm_close_session(); init(8) will take care of
utmp and wtmp when the tty is released.  Clearing them here would make it
possible to create a ghost session by logging in, running 'login -f $USER'
and exiting the subshell.

53f3167d07 Add a PAM module that provides an account management component for checking 
either PAM_RHOST or PAM_TTY against /etc/login.access.o

This uncovers a problem with PAM_RHOST, in that if we always set it, there
is no way to distinguish between a user logging in locally and a user
logging in using 'ssh localhost'.  This will be fixed by first making sure
that all PAM modules can handle PAM_RHOST being unset (which is currently
not the case), and then modifying su(1) and login(1) to not set it for
local logins.

- Spam /usr/lib some more by making libssh a standard library.
- Tweak ${LIBPAM} and ${MINUSLPAM}.
- Garbage collect unused libssh_pic.a.
- Add fake -lz dependency to secure/ makefiles needed for
  dynamic linkage with -lssh.

03adba96a0 Further changes to allow enabling pam_opie(8) by default: 
- Ignore the {try,use}_first_pass options by clearing PAM_AUTHTOK before
   challenging the user.  These options are meaningless for pam_opie(8)
   since the user can't possibly know the right response before she sees
   the challenge.

 - Introduce the no_fake_prompts option.  If this option is set, pam_opie(8)
   will fail - rather than present a bogus challenge - if the target user
   does not have an OPIE key.  With this option, users who haven't set up
   OPIE won't have to wonder what that "weird otp-md5 s**t" means :)

84d6cd8ea1 Bring in a few useful PAM modules. 
pam_krb5 is a Kerberos 5 (Heimdal) authentication module.

pam_nologin checks for /etc/nologin and does the "usual stuff"
	if it is found, otherwise it silently succeeds.

pam_rootok silently succeeds if the user is root, otherwise
	it fails.

pam_wheel silently succeeds if the user is a member of group
	"wheel" (or another nominated group), and fails
	otherwise.

There is an issue with kerberosIV and kerberos5 - if both are
being built, then static linking fails with duplicate symbols.
This will take a bit of work to sort out in the kerberii.
