++Gentoo patch
++------------
++Most everything below still holds, though the libraries required are now
++those used by Gentoo.  Other S/Key libraries may work with a bit of
++tweaking.
++
++The options listed for the module below are no longer valid.  See the
++Gentoo patch section in README for details.
++
++The intended method for configuring PAM is by using the newer module
++specification, with a line like:
++
++auth	[success=done ignore=ignore auth_err=die default=bad] /lib/security/pam_skey.so
++
++This is a combination of the standard "sufficient" and "requisite"
++specifications:
++
++- If the module returns PAM_SUCCESS, we are authenticated and no other
++  modules should be tested.
++- If the module returns PAM_IGNORE, then the module didn't accept its
++  input as an S/Key response, and the next module should try using
++  the input (using the try_first_pass option).
++- If the module returns PAM_AUTH_ERR, then the module accepted an
++  S/Key input but it was invalid.  Do not try any more modules in the
++  stack; the user already chose S/Key authentication.
++- If the module returns any other code, it is a simple error in processing.
++  Set the error flag but try other modules, just in case.
++
++The module is intended to be placed before another authentication module,
++like pam_unix.so; if not, it should be placed before pam_deny.so.
++
++If the newer module specification is unavailable in your version of PAM,
++the "sufficient" specification will work.

++Gentoo patch
++------------
++
++The Gentoo pam_skey patch changes the original module in a number of ways.
++The behavior of the module is changed to make it more consistent with the
++PAM design, and several changes were made throughout the code to make the
++module interact better with the skey library used by Gentoo.  Many of
++these changes will break pam_skey's compatibility with other systems and
++libraries, but this is, after all, the Gentoo patch.
++
++A (not necessarily) exhaustive list of the changes is as follows:
++- pam_skey_access.so is completely removed, since the Gentoo skey library
++  does not support the skey_access() call.
++- The pam_skey.so authentication code is completely rewritten.  The
++  original code contained many references to the standard I/O library
++  (writing to stderr, etc.), as well as inconsistent communication with
++  the PAM libraries.  Also, the authentication process is different, as
++  described below.
++- The options accepted by the pam_skey.so module are different, as
++  described below.
++
++Four options are accepted by the pam_skey.so module:
++  debug                  - This option turns on debug logging.
++  try_first_pass         - This option tells the module to first try using
++                           the authentication token passed from the
++			   previous module as an S/Key response, before
++			   informing the user of the challenge.  If the
++			   token is not valid, the module will proceed with
++			   the standard process of challenging the user
++			   and requesting a response, subject to the
++			   no_default_skey option below.
++  use_first_pass         - This option is identical to the try_first_pass
++                           option, except that if the token is not valid,
++			   it will return silently without challenging the
++			   user.
++  no_default_skey        - This flag changes the behavior of pam_skey.
++                           Instead of immediately challenging the user with
++			   an S/Key challenge, it will present the user with
++			   a standard "Password: " prompt.  If the user enters
++			   the password "s/key" (case insensitive), it will
++			   then challenge the user.  Any other input will
++			   cause the module to pass the given password to the
++			   next module in the authentication stack (usually
++			   pam_unix.so with the try_first_pass option).
++
++The exact behavior of pam_skey.so is detailed below:
++
++1. Retrieve username from PAM, possibly querying the user for it.
++2. If the user does not have any S/Key information, return PAM_IGNORE to
++   proceed to the next module in the stack.
++3. If *_first_pass is enabled, check the given authentication token to see
++   if it is a valid response to the current S/Key challenge.  If so,
++   return PAM_SUCCESS.
++ 3a. If the token is invalid and use_first_pass is enabled, return
++     PAM_IGNORE.
++4. If no_default_skey is enabled, issue a "Password: " prompt.
++ 4a. If the response is anything besides "s/key" (case insensitive),
++     store it as the authentication token and return PAM_IGNORE.
++5. Display the current S/Key challenge and request a response, with
++   input not echoed.  If no_default_skey is enabled, this will only be
++   an S/Key response request; otherwise, it will request either an
++   S/Key response or a system passsword.
++ 5a. If an empty response is given, request the S/Key response again,
++     this time with input echoed.
++ 5b. If the response is a valid S/Key response, return PAM_SUCCESS.
++     Otherwise, return PAM_AUTHERR.
++6. If the response is a valid S/Key response, return PAM_SUCCESS.
++7. Otherwise, if no_default_skey is enabled (the user specifically
++   requested "s/key" authentication), return PAM_AUTHERR.
++8. Otherwise, store the response as the authentication token and
++   return PAM_IGNORE.
