<#
.SYNOPSIS
    Searches LDAP server in given search root and using given search filter
     
 
.OUTPUTS
    Search results as custom objects with requested properties as strings or byte stream
 
.EXAMPLE
Find-LdapObject -LdapConnection [string]::Empty -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com"
 
Description
-----------
This command connects to domain controller of caller's domain on port 389 and performs the search
 
.EXAMPLE
$Ldap = Get-LdapConnection
Find-LdapObject -LdapConnection $Ldap -SearchFilter:"(&(cn=jsmith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"ou=Users,dc=myDomain,dc=com" -PropertiesToLoad:@("sAMAccountName","objectSid") -BinaryProperties:@("objectSid")
 
Description
-----------
This command connects to to domain controller of caller's domain and performs the search, returning value of objectSid attribute as byte stream
 
.EXAMPLE
$Ldap = Get-LdapConnection -LdapServer:mydc.mydomain.com -EncryptionType:SSL
Find-LdapObject -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"ou=Users,dc=myDomain,dc=com"
 
Description
-----------
This command connects to given LDAP server and performs the search via SSL
 
.EXAMPLE
$Ldap = Get-LdapConnection -LdapServer "mydc.mydomain.com"
 
Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com"
 
Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(cn=myComputer)(objectClass=computer)(objectCategory=organizationalPerson))" -SearchBase:"ou=Computers,dc=myDomain,dc=com" -PropertiesToLoad:@("cn","managedBy")
 
Description
-----------
This command creates the LDAP connection object and passes it as parameter. Connection remains open and ready for reuse in subsequent searches
 
.EXAMPLE
$Ldap = Get-LdapConnection -LdapServer "mydc.mydomain.com"
Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(cn=SEC_*)(objectClass=group)(objectCategory=group))" -SearchBase:"cn=Groups,dc=myDomain,dc=com" | `
Find-LdapObject -LdapConnection:$Ldap -ASQ:"member" -SearchScope:"Base" -SearchFilter:"(&(objectClass=user)(objectCategory=organizationalPerson))" -propertiesToLoad:@("sAMAccountName","givenName","sn") |
Select-Object * -Unique
 
Description
-----------
This one-liner lists sAMAccountName, first and last name, and DN of all users who are members of at least one group whose name starts with "SEC_" string
 
.EXAMPLE
$cred=new-object System.Net.NetworkCredential("myUserName","MyPassword","MyDomain")
$Ldap = Get-LdapConnection -Credential $cred
Find-LdapObject -LdapConnection $Ldap -SearchFilter:"(&(cn=myComputer)(objectClass=computer)(objectCategory=organizationalPerson))" -SearchBase:"ou=Computers,dc=myDomain,dc=com" -PropertiesToLoad:@("cn","managedBy")
 
Description
-----------
This command creates explicit credential and uses it to authenticate LDAP query
 
.EXAMPLE
$Users = Find-LdapObject -LdapConnection (Get-LdapConnection) -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com" -AdditionalProperties:@("Result")
foreach($user in $Users)
{
    try
    {
        #do some processing
        $user.Result="OK"
    }
    catch
    {
        #report processing error
        $user.Result=$_.Exception.Message
    }
}
#report users with results of processing for each of them
$Users
 
Description
-----------
This command connects to domain controller of caller's domain on port 389 and performs the search.
For each user found, it also defines 'Result' property on returned object. Property is later used to store result of processing on user account
