Bulk removal of Published certificate info from users properties.

Hello all ,

I am trying to remove usercertificate and usersmimecertificate value from users properties but facing an issue ....below is the script :::

  $users = get-content "c:\input.txt"  

                foreach($usersam in $users)

                {

                                $Searcher = new-object DirectoryServices.DirectorySearcher

                                $Root = [ADSI]("LDAP://" + "DC=guitar,DC=intra")

                                $scope = "subtree"

                                $Filter = "(&(objectclass=user)(samaccountname=" + $usersam + "))"

                                $Searcher.SearchScope = $Scope

                                $Searcher.Filter = $Filter

                                $Searcher.SearchRoot = $Root

                                $accnt = $Searcher.Findone()

                                if($accnt -ne $null)

                                {

                                $userdn = $Objuser.properties.distinguishedname

                                $user= New-Object DirectoryServices.DirectoryEntry ("LDAP://kingfisher.guitar.intra:389/$userdn")

                                $User.Putex(1,"userCertificate",0)

                                $User.Putex(1,"userSmimeCertificate",0)

                                $user.setinfo() 

 $userdn

                                }

                }
