Filtering multiple null values from Get-ADUser-CodePudding

I'm still working on learning powershell. I need to pull email and manager email from AD accounts in a group but exclude any records that have manager blank or email blank. I don't think I can 'where' for two where conditions, so I can get one or the other.

Get-ADGroupMember -Identity "groupname" -Recursive | Get-ADUser -properties * | where manager -NE $null | select displayname, EmailAddress, @{Name="ManagerEmail";Expression={(Get-ADUser -property Emailaddress $_.manager).emailaddress}} | export-csv -path c:\data.csv -NoTypeInformation

How would I go about getting both filtered out?

CodePudding user response：

You can use and should use the Active Directory Filter or LDAP Filter for this instead of doing the filtering with powershell:

$group = (Get-ADGroup groupname).DistinguishedName
$managerMap = @{}
$params = @{
    LDAPFilter = "(&(memberof:1.2.840.113556.1.4.1941:=$group)(mail=*)(manager=*))"
    Properties = 'mail', 'manager'
}

Get-ADUser @params | ForEach-Object {
    if(-not $managerMap.ContainsKey($_.manager)) {
        $managerMap[$_.manager] = (Get-ADUser $_.manager -Properties mail).mail
    }

    [pscustomobject]@{
        DisplayName  = $_.DisplayName
        EmailAddress = $_.mail
        ManagerEmail = $managerMap[$_.manager]
    }
} | Export-Csv 'c:\data.csv' -NoTypeInformation

Details of the LDAP Filter:

(& # AND, all conditions must be met
    (memberof:1.2.840.113556.1.4.1941:=$group) # user is a member of `$group` (recursively)
    (mail=*) # mail attribute is not null
    (manager=*) # manager attribute is not null
) # closing AND
