Redirection loop on a https site with Multi-Domains and Domain-Mapping

Redirection loop on a https site with Multi-Domains and Domain-Mapping.

Hi.
We have a networked multi-domain system where three out of the four domains are http and one is https.

When running version 4.1.4.2 of Domain Mapping with version 1.3.4.1 of Multi-Domains, everything worked fine on all sites. But when updating to 4.3.0.4 and 1.3.4.3, the https site starts to do the redirection loop. (The wp-admin of the https site still works).

I had tried setting up Apache to redirect any http requests over to https. This will cause the loop too. When I remove any setup for port 80, attempt to visit port 443 at https://thedomain.com seems to be sending me back over to the http port 80.

Is there a setting that I'm missing somewhere? When we needed to add the domain, it didn't allow http, so that was editing in the database.

Any assistance would be much appreciated :wink:
Thanks.
