After integrating with AM ... getting random errors during SSO ...
I think the error was addressed by increasing the limit on header size in Jetty (IDM) and Tomcat (AM) from 8k -> 10k. If so, doc as part of at least this section in the full stack sample
Based in part on recent discussions in the #idm Slack channel, https://forgerock.slack.com/archives/C03120Q9K/p1527706462000387
May need separate JIRAs for the AM and IG docs, for when they're integrated.
