I am brand new to dot net nuke, and have been asked to make some updates to a website that uses it.  I am trying to figure out how to turn on password aging.  I logged in as an Admin, and went to roles/user settings, and I can see the Membership Provider and Password Aging settings displayed, but they are all read only.  Under Membership Provider, it says you have to edit these settings in the web.config.

I opened the web.config file, and I see where you can set the Password Retrieval and Password Reset propertieds (and all the other Membership Provider properties in the AspNetSqlMembershipProvider node), but I see no examples of how to set Password Expiry and Password Expiry Reminder properties.  Does anyone have an example of this from the web.config file that they can post?
