I've installed Openshift Origin as described in the comprehensive guide on a single box (all in one setup). The problem is, that I can't add my node to a district, therefore it's not possible to use Openshift on that machine.
When I type
oo-admin-ctl-district -c add-node -n Default -i node.example.com
I get
/usr/sbin/oo-admin-ctl-district:215:in 'block in <main>': undefined method 'casecmp' f or nil:NilClass (NoMethodError)
from /usr/sbin/oo-admin-ctl-district:178:in `block in collate_errors'
from /usr/sbin/oo-admin-ctl-district:176:in `each'
from /usr/sbin/oo-admin-ctl-district:176:in `collate_errors'
from /usr/sbin/oo-admin-ctl-district:213:in `<main>'
I tried to pin the problem down, an I think it's because the node doesn't connect to the message queue correctly as oo-mco ping gives me
broker.example.com time=94.30 ms

I checked my config with the comprehensive guide several times, but couldn't find any problem yet. Any help or tipps on this would be greatly appreciated.
Don't know what I am actually doing, but this post did solve my problem so far

Seems that I had the same issue, and that Openshift Origin comprehensive Depoyment guide needs an update.
