SharePoint 2010 Claims Auth/FBA - Reset password not working

Question

I have a SP site with Claims Authentication and FBA setup. Dual auth Win/Forms is working perfectly.

I have a asp:PasswordRecovery control on app page. It appears to lookup the account correctly - returning 'not found' messages if the username is not found. However, it fails to reset the password with the following execption:

Exception information: 
   Exception type: NotImplementedException   
   Exception message: The method or operation is not implemented.   


Thread information:

Thread account name: SERVER01\SPS_Farm 
Is impersonating: False

Thanks in advance.

Update:
I added:
enablePasswordReset="true"
to the app web.config AND the token-service web.config

Wrote some some code to do a manual test, and still got this when my code tried to 'reset' the password:
This provider is not configured to allow password resets. To enable password reset, set enablePasswordReset to "true" in the configuration file.

This may not help since you seem to be looking up the user properly... but if you aren't doing this I know you can run into not implemented issues:

Make sure to get an instance of the user using the appropriate Membership Provider.

e.g.

MembershipUser myUser = Membership.Providers["aspMembership"].GetUser(userName, false);

Hope this helps.
