Teach passwd about a new "mixpasswordcase" login.conf parameter. If this

Browse Source 
parameter is missing, or specified as above, then passwd behaves as normal
when the user enters an all lower case password -- i.e., it prompts them
to use mixed case, and will only grudgingly accept an all lower case
password.

If you negate this entry in login.conf, with "mixpasswordcase@", then
passwd will allow all lower case passwords without complaining.
