Using Windows Powershell to do openldap quey. How?

AFAIK you can use the standard LDAP providers in System.DirectoryServices.DirectoryEntry

$de = New-Object System.DirectoryServices.DirectoryEntry("LDAP://Path")

Can you give me a example of what your trying?

For starter, I just want to query all entries in the OpenLDAP server and list them out.

host: ldap.ms.com
port: 389
Base: dc=ms, dc=com
anonymous bind

With Powershell, how do I list out all entries in this ldap server?

Thanks

Try this.. I am not sure the filter is correct for OpenLDAP, but I belive it is.

$root = "LDAP://ldap.ms.com/dc=ms,dc=com"
$filter = "(&(objectcategory=*))"
$dsearcher = new-object System.DirectoryServices.directorysearcher($root,$filter)
$dsearcher.pagesize = 1000
$dsearcher.findall()

you know.. try objectclass instead of objectcategory

It works for AD but does not work for openLDAP...

Did you try objectclass?
What error did you get?

What happens if you just do this?

$de = new-object System.DirectoryServices.DirectoryEntry("LDAP://ldap.ms.com/dc=ms,dc=com")
$de.psbase.children

Another option is to using
System.DirectoryServices.Protocols

I can post example, but I will need to install Linux and install openldap (already started)

Yet another option and it maybe the easiest for you
http://www.codeplex.com/PowerShellCX

This is free and has a built in cmdlets for openldap queries

It says cannot login or something.  I will take a look at the PwershellCX.

Ok... I will still try to post something using System.DirectoryServices.Protocols

I just installed PSCX.  It has "GET-PSPROVIDER" command that allow me to check my AD LDAP.  I haven't found a way to check OpenLDAP yet...

use Get-ADObject

I should get to testing the openldap code I have tonight.

Ok.. I got it working for me
###################################
$DN = "LDAP://192.168.0.104/dc=example,dc=com"
$auth = [System.DirectoryServices.AuthenticationTypes]::Anonymous
$de = New-Object System.DirectoryServices.DirectoryEntry($DN,$auth)
$ds = New-Object system.DirectoryServices.DirectorySearcher($de,"(objectclass=*)")
$ds.FindAll() | ft
###################################
Output

It says:

New-Object : Cannot find an overload for ".ctor" and the argument count: "2".
At C:\Scripts\test.ps1:3 char:17
+ $de = New-Object  <<<< System.DirectoryServices.DirectoryEntry($DN,$auth)

and then it list out my own AD/LDAP info...  For some reason it is not taking my LDAP based address.

LDAP://CN=0013ceede78a,OU=MAC-AUTH,DC=research... {samaccountname, useraccountcontrol, primarygr...

Did you specify server?
LDAP://<SERVER>/CN=0013ceede78a,OU=MAC-AUTH,DC=research...

Normally this would not be required, but dont think discovery it going to work for you.

Would you mind posting your $DN? You can change the "names" but keep the format.

I did add it but it is not taking it.  I am running the Powershell script on one of my Windows server and I want to grab a Linux OpenLDAP's information.

$DN = "LDAP://ldap001.linux.ldap.com:389/dc=linux,dc=ldap,dc=com"

Thats curious. It worked for me (against my OpenLDAP server.)

Can you attach to the server using ldp.exe from the support tools?

Installed and ldp works fine.  Humm... why?

So the "System.DirectoryServices.DirectoryEntry($DN,$auth)" does not work...  It says

New-Object : Cannot find an overload for ".ctor" and the argument count: "2".
At C:\Scripts\test.ps1:3 char:17
+ $de = New-Object  <<<< System.DirectoryServices.DirectoryEntry($DN,$auth)

Further info.. if I don't use $auth and use "System.DirectoryServices.DirectoryEntry($DN)" instead, it will say:

PS C:\Scripts> $ds.FindAll()
Exception calling "FindAll" with "0" argument(s): "Logon failure: unknown user name or bad password.

Any idea?

that works!!  Thank you.
