Describe the bug
When a member recives a link, and does not have the session opened, the link takes him directly to the login screen. When the user is already logged, the user loses the link to which is supposed to go and redirects to the homepage, instead of going to the initial link.

To Reproduce
Steps to reproduce the behavior:

1. Log into system.
2. Press the Force users to authenticate before access organization option.
3. Try to access to a link without the session opened.
4. Log in with your user.
5. See how it redirects to the homepage and the initial link is lost.

Expected behavior
It should redirect to the initial link after the logging in.
