Your Windows password could not be retrieved by Notes Single Logon: Access is denied

Despite Technote 1220656, which says this error was fixed in 7.0.1, I’m getting this error in 8.0.2 CCH2 after I changed my Notes/Windows password. Is this a regression?

Subject: fixed after complete reboot

Don’t believe what the messagebox says about having to log off, in this case a complete reboot was needed to make SSO work again.
