LN 8.5.1 FP1: Is there an open SPR for broken SSO on Windows 7 64-bit?

I know this has been mentioned frequently in this forum, but I have yet to hear if the following issue is being addressed:

Using Lotus Notes 8.5.1 w/FP1 on Windows 7 64-bit, Single Sign-On will not work. User is prompted for a password even though the service is running.

…Is there an SPR for this issue and if so, what future release might we see a fix? Thanks for the help!

I am pretty sure that SSO on 64 bit Windows 7 is not support as of yet
