Yes, expiration is a shadow-only function. Check out the online docs at
/usr/doc/HOWTO/Shadow-Password-HOWTO.
Note, however, that it is quite probable that you already have the "Shadow
Suite" installed, so you should try enabling shadows before you go through
the trouble of finding all the source code and compiling, like the HOWTO
says.
Expiration information is stored in the /etc/shadow file, once you enable
shadow passwords.
In short, run pwconv to convert from standard passwords to shadow passwords.
Then you will need to set all of the expirations, etc, for your users.
(BTW, once shadow passwords are enabled, you will see a new "tab" in
userconf gui that allows you to set the expiration, lockout, etc information
without having to manually edit the file(s).)
