[keycloak-user] problem with keycloak on openshift

Wed Jul 1 04:07:20 EDT 2015

Hi guys, I have deployed an instance of keycloak on openshift
following the steps described here:

https://github.com/keycloak/openshift-keycloak-cartridge

The operation apparently went ok and I have been able to login to the
instance and see kc administrative interface.

Problem is that after a while, I am no longer able to login to the
instance. Not even if I restart it.

This is the error I see when trying:

Bad Request

Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

X-Forwarded-Host

/n

And I get that with both ffox and chromium on linux

this from curl:

$ curl -L -v https://kc-paolo.rhcloud.com/
