I do the sysadmin-thing for a living, and I'm terrible at writing blurbs like this. I deal mostly with various linux infrastructure, and a small cluster. I tend towards not liking black/opaque boxes which I'm to have an informed opinion about or have any kind of responsibility for. I really like knowing "how stuff works" and how "stuff" talks to "other stuff", as I feel it gives me a better foundation to make informed decisions.

comment Varnish running out of open ports, lots of SYN_SENT connections
When you say you're running out of open ports, exactly what do you mean, which component is complaining and on which side (browser -> varnish, varnish -> apache) ? How is traffic directed at varnish is it NATed ?

comment Tunnel is up but cannot ping directly connected network
I'd give packet-tracer on the ASA a try, it's previously at least helped me pinpoint where things are going wrong. I.e. you could run packet-tracer on the combination of icmp/ping that's failing and see what decision your ASA made for it. (And, it's not entirely unlikely that your problem is NAT. If you do NAT of your hosts going out, you'll explicitly have to exempt tunnel traffic from NAT).

comment getent and ldapsearch results are inconsistent concerning the loginShell
I'm assuming there's a typo in your cut/paste where the result of ldapsearch has the attribute oginShell, rather than the attribute loginShell ? :) As tentatively, with a lack of a loginShell attribute nss/sss might fill in the blank for you with /bin/bash.
