Unfortunately, Jive does not support multiple domains for LDAP out-of-the-box. However, here are some recommended options available to you.
a. Provision a virtual directory in front of your Active Directory servers. This will enable Jive to leverage its native Active Directory integration by pointing to a single base DN.
b. Provision an ADAM or AD LDS server in front of your Active Directory server. Jive can then be pointed to a single base DN.
c. Engage Jive Professional Services to setup a nightly sync of user profile and security groups using Jive's native ADFS to authenticate.
