OTP SSPR greyed out email address not showing

Hi,

According to http://technet.microsoft.com/en-us/library/jj134288(v=ws.10).aspx#email_gate if the SSPR Registration mode is set to Read-Only then the user will be presented with the screen showing them their registered email address in read only/greyed out mode.

However, we have just deployed this solution in both lab and production, and neither displays the greyed-out registered email - has one of the service packs/hotfixes changed this?

thanks,

dw
