'remember me' functionality broken when SSO is turned on

The built-in 'remember me' functionality (using the 'remember' cookie) is broken when SSO is enabled. The cookie is still created & the date is still a year in the future... but Fisheye/Crucible appears to ignore it. If I disable SSO, the functionality starts working again. If I re-enable SSO, it breaks and I need to re-login every time I start a new session.
