I can't figure out how to share notebooks (with uploaded files) between domains without getting the "HTTP ERROR 403".
I have domain1.com, domain2.com, domain3.com etc.
In each domain I have added a Virtual Host:
mail.domain1.com, mail.domain2.com, mail.domain3.com etc.
All users authenticate against their virtual host respectively.
So, email@example.com shares a notebook with some uploaded files/images in it. The path to the image(s) is
firstname.lastname@example.org tries to access the notebook page with the uploaded file and gets "permission denied: you do not have sufficient permissions". That is (I think) because the user is authenticated against mail.domain2.com and is not permitted to access mail.domain1.com.
Is there a way to set things up to get this to work?
