You didn't really say which thing you are using which does not 
respect the configured values.

I assume what you are seeing is caused by the default PAM 
configuration. IIRC there was some change for trixie. Reassigning to PAM.
@Sam: I'm open to dropping config directives from login.defs, let me 
know.
