Subject: Re: Too many redirects when running behind load balancer? 

Yes, I used the empty `passwd` file from example. When I then click on one of the logbooks, I get to the page where I can register a user (see attached screenshot). After clickin on "Save" for the user registration, I again get the redirect error. Once there is a registered user (i.e. a non-empty password file) the redirect issue is persistent. Any idea where the problem might be? I just emptied the password file again, so you can have a one-shot, if you like.

Btw. I have SSL termination in the load balancer, so ELOG does not need to do any SSL related things (the swarm is in a locally isolated network, so all internal communication between the load balancer and the swarm machines are safe). Maybe that's the issue? On the other hand, the main page loads fine and uses SSL termination too, so I don't know, maybe there is logic behind the authentication which collides with the SSL termination.

Yes I see the redirects. You say with the example logbook it works, right? Is it the password protection which triggers the problem or anything else? Does it work if you take out the password protection? The key is to identify which setting in your config file triggers the problem, so you can bracket the problem down between the example logbook and your logbook definition.
