Why can I only see 1000 users in Directory Connector?

NG Firewall can read more than 1000 users from Active Directory, but your AD server must be configured to send more than 1000 users. Run these commands from the command prompt on the AD server to send up to 5000 users:

ntdsutil.exe
LDAP policies
Connections
Connect to server addomainname.local
Quit
Set MaxPageSize to 5000
Commit Changes
Quit
Quit

NOTE: Replace "addomainname.local" with your domain
