We have a custom MembershipProvider implementation using form-based authentication (FBA) under Sharepoint 2007.

I've searched high and low on Google, but only found:

• Active directory and FBA implementations to allow users to change their own password
• Active directory instructions (including video!) for administrators to change other users' passwords

Have we missed an option to enable the latter under FBA? Should this work by default and is the MembershipProvider misbehaving?

The procedure to do this as under active directory would be ideal, but the "Change Password" link does not appear in the Edit User screen. We verified that the logged-in user is a site collection administrator.
