enhanced apache password security

Hi,

I am running Apache 1.3 (OpenSUSE 10.2) on an intranet server behind my
firewall.

I am trying to enhance password security by adding:
a. a complex password requirement
b. password aging
c. lockouts after a given number of invalid password attempts
d. user modifiable password functionality

Is there an Apache 1.3 or 2 module that will enforce the above
requirements? Is there any other solution?

Any advice would be appreciated.

Thanks,
Larry
