Yes that's true, it would work only with 636, not 389.

Yes, I understood that, and I said before, when I set "pool.default.serverset.srvrecord.service = ldaps", the parameter "vars.dns" is ignored by ovirt...
When I use "vars.dns = dns://ad_server.mydomain.com", restart ovirt-engine, attempt to login and then check the logs, I see in the logs it is still trying to use "_ldaps._tcp.university.mydomain.com" instead... It really totally ignore the vars.dns parameter !

Now if use only "vars.dns = dns://ad_server.mydomain.com", and disable (comment) "pool.default.serverset.srvrecord.service = ldaps", in the logs, I see the right DNS used (ad_server.mydomain.com), but as you said, on the wrong port.

If I specify the port with "vars.dns = dns://ad_server.mydomain.com:636", I still see in the log it's trying to use port 389. Which mean the port number is totally ignore in "vars.dns" parameter.

Interesting, but here _ldap_tcp is not used. And I'm not a java delopper, I won't know how to do with these classes etc...

So does it mean there is no way to specify to ovirt config files that I want to use another DNS on 636 port ?

Ok, no problem, I'll do that.
