When binding the DDP to an Active Directory server, one might want to query the DC to check which command is able to import users to the DDP.

You can achieve this by using the Linux 'ldapsearch' command as per the following example:

ldapsearch -x -h 1.2.3.4 -p 389 -b dc=abcd-ldap,dc=xyz,dc=company,dc=com
"(|(objectclass=group)(objectclass=user)(objectclass=posixGroup)(objectclass=posixAccount))" dn cn objectclass sAMAccountName uid memberUid

You can try to adapt this Linux command to make a single query that returns the users wanted, then that query can be used in the DDP web GUI to import the users.
