LDAPS connection

Hi Everyone

I have used: adldap.contoso.com.vn for LDAP connection. So I want to use adldap.contoso.com.vn for LDAPS connection too. But I dont know if use adldap.contoso.com.vn, have any impact on the future? Because I have so many application so can not change to use another.
I need to clarify risk and benefit between adldap.contoso.com.vn and adldap.contoso.contosocorp.vn.

So do you know if use adldap.contoso.com.vn, have any impact on the future?
