Disconnect particular user whose idle session is 30 mins

Hi,

Please help me disconnect particular user whose idle session is 30 mins

## max number of idle minutes for sessions to keep

$intOlderThan = 30

$serviceInstance = Get-View 'ServiceInstance'

## get the session manager object

$sessMgr = Get-View $serviceInstance.Content.sessionManager

## array to hold info about stale sessions

$oldSessions = @()

foreach ($sess in $sessMgr.SessionList){

    if (($sess.LastActiveTime).addminutes($intOlderThan) -lt (Get-Date) -and

          $sess.Key -ne $sessMgr.CurrentSession.Key){

        $oldSessions += $sess.Key

    } ## end if

} ## end foreach

## if there are any old sessions, terminate them; else, just write message to the Warning stream

if (($oldSessions | Measure-Object).Count -gt 0) {

    ## Terminate sessions than are idle for longer than approved ($intOlderThan)

    $sessMgr.TerminateSession($oldSessions)

} ## end if

else {Write-Warning "No sessions that have been idle for more than '$intOlderThan' minutes; no action taken"}
