How to setup ldaps with split dns system.

I have .com for the inside and .edu for the outside. I do not own the .com only the .edu. The cert for the ad is linked to the .com. I can not make it .edu because things inside will brake. I was told the host name i use in the ldap screen and cert has to be the same. but in my case it can not be. How can i fix this problem so i can setup ldaps in jamf pro cloud version. i also want it hook it up to my inside jim and adcs server.
