Expired passwords and Display Managers

[Tom Allison <tallison@tacocat.net>]

I've been doing some testing with expiring passwords (30 day limit, 5 
day warning, 3 days expires) on my server and noticed a very nasty problem.

WDM does not notify me of a pending expiration.

This means that there is no way for a "typical" user to know that their 
password is about to expire.

I consider this to be a very bad thing.

Are there alternatives?
Configuration settings in WDM?
Alternative Display Managers (not KDM or GDM please, I use neither)?
