Database only loads 1/3 of members of Active Directory Group

I recently upgraded to Openfire 4.6.4 from 4.5 on CentOS 7, and am using the embedded database. During setup the Active Directory integration only reads about 1/3 (250 of 700ish) of the members of the user group. Any troubleshooting suggestions would be appreciated.

If you had setup OF to load members from a group there are some issues with AD.
There is a PR to fix it but it is labeled to the upcoming version 4.7.
So you have to wait or change your base dn in OF to use your domain
