[galaxy-dev] possible bug found - unable to log out of impersonated user when external authentication enabled

Hi all - We are using a SSO system so that user's authenticate externally from Galaxy. when I impersonate a user then try to log out as that user, I'm unable to. I get the page " Access to Galaxy user controls is disabled User controls are disabled when Galaxy is configured for external authentication." If I close the browser down, and restart, I get my SSO log in page, but when I get to Galaxy, I'm still impersonating the user.
