Perhaps authenticating the users that log in with MD5 on the Linux machine
and at same time storing their passwd in DES in a copy of /etc/passwd ?
And after some time, you'll have (at least) most passwds also in DES -
except the users, who didn't login 'till that time.
As I know, you don't have to alter the pam_unix module for that. You can
easily use the stacking feature of pam and write your ovn module taking
the passwd and store it in the other file.
I think, you can copy most of the code from the pam_unix module... I think
you should take some code of the pam_unix password management (passwd
changing) section and use it in the new modules auth section (for writing
the (DES) passwd to a file).
Then you can use you module and specify the use_firstpass (or
try_firstpass) argument to your module.

The module should not prompt the user for a password. Instead, it should
obtain the previously typed password (from the preceding auth module),
and use that. If that doesn't work, then the user will not be
authenticated. (This option is intended for auth and password modules
Did you understand what I mean?
It is just a thought...
(It would be less heavy to implement than porting the pam_unix module to
Maybe I'm fully false...
And have you checked out the other lists etc. handling that problem?
gooooogle is your friend ;-)
