Just to make you absolutely clear: using compat tree will not help you
at all. Nothing else in FreeIPA could help you in getting Kolab to work
with both IPA and AD users at the same time.

It would be nice if kolab could grow a capability to connect to multiple
LDAP servers at the same time, with non-overlapping user and group
trees. I don't think it is there now and I don't see other possibilities
here.
