AD sync project doesn't dump all the accounts

Hello everyone,

I have created a sync project with an AD domain. I can dump the information into One Identity 8.1. The problem is that seems there is 400 accounts in the domain, however, I can only dump about 80 accounts into the system. I did not see any message error in the logs, any filter...

Any idea whats it happening?

Thank you in advance.

Beatriz.
