[Building Sakai] Unexpected login prompts - Sakai 2.6.0

[Zach A. Thomas]

This is consistent with a cluster environment where the load balancer
does not properly "stick" the user to a single server. Thus, they're
logged in on one of the nodes, but the next request goes to some other
server where they're _not_ logged in.

Can you confirm whether you are running a cluster of app servers? And if
so, how are you performing load balancing?
