[cipher-ctr.c cipher.c]

Bug #892: Send messages from failing PAM account modules to the client via
   SSH2_MSG_USERAUTH_BANNER messages.  Note that this will not happen with
   SSH2 kbdint authentication, which need to be dealt with separately.  ok djm@

 2004-07-01 12:38:14 +10:00
Darren Tucker 59e06026d7 - (dtucker) [auth-pam.c] Check for buggy PAM modules that return a NULL 
appdata_ptr to the conversation function.  ok djm@

By rights we should free the messages too, but if this happens then one
of the modules has already proven itself to be buggy so can we trust
the messages?

monitor_wrap.h] Bug #808: Ensure force_pwchange is correctly initialized
   even if keyboard-interactive is not used by the client.  Prevents segfaults
   in some cases where the user's password is expired (note this is not
   considered a security exposure).  ok djm@

Darren Tucker c376c8647e Enable commented-out "if (compat20)" test. (Should not have been committed.) 2003-12-18 16:08:59 +11:00
Darren Tucker 07705c788e - (dtucker) [auth-pam.c] Do PAM chauthtok during SSH2 keyboard-interactive 
authentication.  Partially fixes bug #423.  Feedback & ok djm@

Some background on why this is the way it is:
* Solaris 8's pam_chauthtok ignores the CHANGE_EXPIRED_AUTHTOK flag, so
  we must call do_pam_account() to figure out if the password is expired.
* AIX 5.2 does not like having pam_acct_mgmt() called twice, once from the
  authentication thread and once from the main shell child, so we cache the
  result, which must be passed from the authentication thread back to the
  monitor.
