I have an inheritable 'nav' project that I'm using as a docked view. The user logs in using that docked view. However, when they navigate between projects their authentication resets and they have to log in again. Is there a way to make the auth 'stick'?
If you're using the same IdP on all of them, you could try going to Security...General and under the top option for "System Identity Provider" and uncheck "Always ask the IdP to re-authenticate users by default" to see if it helps.
