Cannot login admin after using dashboard on ios

I find this issue while working with my app. At first I think there s something wrong with my app, then discover it is an weird issue on IOS. How to replicate:

1.Open dashboard with authentication on safari
2. Close dashboard, open admin, enter user and pass. Now you cannot login although input right authentication info

I test myself and another user report the same issue. So do anyone have idea what is happening and how to solve

Tks

If anyone have hint about this conflict. What node-auth do lead to un-authorize admin
