Newly created accounts not appearing immediately

[bunjiboys]

Currently, if someone adds a new account using the web ui, any existing user sessions will not see the new account, until they log out and log back in, as the access checks are done in login.

We need to find a better way to either force refresh it , invalidate all existing sessions on account creation or simply not cache the list of available accounts in the user session (need to ensure it won't adversely impact performance to do so)
