Binding an Open Directory Master to multiple Active Directory domains

We have an Open Directory Master (OS X Server 5.0.15 on El Capitan 10.11.3) already bound to an Active Directory domain. So far so good. Now we want to bind the OD Master to an additional Active Directory domain.

The two AD domains have a two-way trust relationship but they aren’t in the same AD forest.

Should we be concerned of any potential issue that could arise from the additional binding?

Thanks in advance for any reply and suggestion.
