HAProxt 1.8 and ADFS Redirect different domain

Help!
1

Hi,

I have this scenario:

client —> Ha Proxy (cert fqdn: adfs.com) --------> ADFS (cert fqdn: adfs.int)

So in the client browser they will type https://adfs.com/adfs/ls/idpinitiatedsignon.aspx and re-directed to ADFS with a cert of fqdn: adfs.int.

My current configuration below does not work. I’m getting error “503 Service Unavailable” if I type in https://adfs.com. But it will work if I use https://adfs.int.

Any suggestion?

Thank you.
