This is really weird : If I manually run : dig

In the logs I see this : "An error occurred while attempting to query DNS in order

The same happens with : dig @any_of_the_4_AD_server _ldap._tcp.my_forest_name.com SRV
^_ldap
So why dig can resolve it but not ovirt ?
you use '_ldaps._tcp' in ovirt not '_ldap._tcp' as in dig.
And '_ldaps' is what's missing in your DNS.

Interesting, now I understand better...

"ldaps" is also a kind of conventional "microsoft SRV record" like
_ldaps_tcp ?
Unfortunatelly using '_ldaps._tcp' is not any standart. But that's what
usually people do if they can't use startTLS.
With startTLS I didn't have any success (and I don't really get why) :

This message doesn't say much. Can you please send full Java exception

Don't forget to also remove lines:
pool.default.ssl.enable = true
pool.default.serverset.srvrecord.service = ldaps
