The original password reset portal interface had separate textboxes for user name and domain username = "username" and domain = "domain"In update 2 (and update 3) the "domain" textbox has been removed and there is just the username textbox, which requires (at least in my configuration) the domain to be pre-pended to the username "domain\username" rather than just "username" username = "domain\username"If you had SSPR working and upgraded to Update 2 or 3 you may need to change the way you enter the username or you will get the error above. This took me a while to work out.

Yup, this should have been documented it better The reason for this change is that the same textbox will now support UPN. That's a DCR we took. In post RTM, we are going to add example on that page so users will have a better idea on what to type there.The FIM Password Reset Blog http://blogs.technet.com/aho/

So now we are in post RTM, and there is still no example. Maybe this is forgotten and maybe there should be an update for this?

I am having the same issue, so i want to customize the page to show an example to my users since we are a multi domain setup. the problem I have is that I cannot seem to be able to customize the password portal page. Does anyone have any examples that they can share?

install RTM Update 1.

Thanks, I am just actually getting ready to do that. Reading through the release notes, i did not see any mention of it, so assumed that it did not resolve.

update 1 still doesn't support customization, but it looks much better than before

I haven't tried it yet, but i guess it's not entirely unthinkable that you can edit the page with Sharepoint designer and guide your users that way.
