How to set up multi-domain in Modx Revolution?

Question

MODX

Hello.
There is a site, for example, site-main.ru. Through the CNAME directive for the site, let's say site-mirror.ru redirect is registered:
wl.site-mirror.ru CNAME site-main.ru . As a result, upon request in the wl.site-mirror.ru browser, the content of the main site site-main.ru is loaded. But there are some problems with the work of this mirror site. For example, authorization via HybridAuth does not work.
The question is how to organize the separation of settings for different domains, but not through contexts, since there are a lot of pages and they will be 100% the same on all such sites. I draw your attention to the fact that we are not talking about different subdomains, but domains. As an example, I can bring the site mamba.ru to work, which has many clones with the same fu-th but different branding.
It's all on the Modx Revolution engine.
I will be glad to any ideas.
