Issue/Introduction

When using AWI in a clustered fashion with multiple Tomcat servers, in combination with SSO, the SSO login always fails on on one of both servers while the other works.

Environment

Use only lowercase for the host name in UC_KDC_SETTINGS, for instance:

HTTP=HTTP/host1.domain.local;HTTP/host2.domain.name.local
