SSO with external url doesn't work

Question

Hi,

I have running crowd, jira and confluence. If I access local via IP-Adress (192.x.x.x), SSO is working perfectly.
But if I would access via external URL, SSO doesn't work. The Base-Url of jira is jira.example.com and for confluence is wiki.example.com
If I would set the "SSO Domain" to .example.com, Crowd always response with "The supplied domain is invalid."

I have used the Apache-Configuration as described in documentation (Using Apache with virtual hosts and mod_proxy ):
http://confluence.atlassian.com/display/CONF31/Using+Apache+with+virtual+hosts+and+mod_proxy

What I'm doing wrong?

The solution add "ProxyPreserveHost On" on every virtual host configured.
