Users in ADGroup with direct reports - powershell

Question

I want a list of users in ATL Users that have direct reports.
Part 1: Group Membership
I can get the users in a group.
Get-ADGroupMember "ATL Users" | Where objectClass -eq "user"
Part 2: Filter for Direct Reports
I can get a list of users with direct reports, but very slowly (scans entire tree).
Get-ADUser -Filter "DirectReports -like '*'"
Question
How can I get the list of users in ATL Users then -Filter those users by if they have direct reports?

Answer 1

This is readily done with an LDAP filter using memberOf. If this is a one-off query and you know the group's distinguished name (cn=ATL Users,ou=groups,dc=domain,dc=gTLD in this example), you can use:
get-aduser -LDAPFilter "(&(memberOf=cn=ATL Users,ou=groups,dc=domain,dc=gTLD)(directReports=*)(objectClass=user))"
If you will be running this query repeatedly, it would be best to get the group object from a search so directory restructuring won't break your query.
PS> $groupFQDN = (get-adgroup -identity "ATL Users").distinguishedName
PS> $groupFQDN
CN=ATL Users,OU=NewGroupsOU,DC=company,DC=gTLD
PS> get-aduser -LDAPFilter "(&(memberOf=$groupFQDN)(directReports=*)(objectClass=user))"

You can just pipe a foreach into Get-ADUser -filter after Get-ADGroupMember
Example:
Get-ADGroupMember "ATL Users" | Where-Object {$_.ObjectClass -eq "user"} | foreach {Get-ADUser $_.samaccountname -properties Name, DirectReports | Where-Object {$_.DirectReports -like "*"} |Select Name, DirectReports}
