Here's an example to list all accounts in the directory using the Novell
LDAP library, which can be found here:
. Download the
lib-v2.1.7.zip file for the library. There are also some great examples in
C# that you can download.
$ldap = new-object Novell.Directory.Ldap.LdapConnection
$version = [Novell.Directory.Ldap.LdapConnection]::Ldap_V3
$port = [Novell.Directory.Ldap.LdapConnection]:
$scope = [Novell.Directory.Ldap.LdapConnection]::Scope_One
$filter = "(objectclass=*)"
$attrs = [Novell.Directory.Ldap.LdapConnection]::All_User_Attrs
$ldap.bind($version, "cn=user,o=orgname,c=US", "password")
$results = $ldap.Search("o=orgname,c=US", $scope, $filter, $attrs, $true)
$ldap = $null
