Horde/Kronolith “no free/busy url”

I’ve recently tried to setup the Horde Groupware 5.2.22 and I’m trying to setup the freebusy option for my calendar but I every time anybody added an event, it came up with an error

“Error retrieving free/busy information for user@domain: No free/busy URL found for user@domain”. 

I have used my IMAP server to do the authentication and I’ve my Address Book configured to look for my ldap.

How and where can I tell the Kronolith to look for the freebusy url?

I’ve the url in correct format “http://localhost/horde/kronolith/fb.php?u=username“ on my ldap .

Thank you.

¿no me imprime una imagen guardada en mi base de datos?

No se si mi codigo esta pobre o esta mal por lo que la imagen la guerde en blob o ¿es esta la forma?

<?php     include("conexion/conexion.php");     $  result = mysqli_query($  conexion,'SELECT * FROM noticias');      if ($  row = mysqli_fetch_array($  result)){         echo "<div style='color:black' border='1'> \n";          do{           echo "<h1>".$  row["titulo_noticia"]."</h1><br><img src=".$  row["fotos_noticia"]."/><br><h2>".$  row["subtitulo_noticia"]."</h2><br><p style='color:black'>".$  row["descripcion_noticia"]."</p><br><label style='color:black'>".$  row["autor_noticia"]."<br>".$  row["fecha"]."</label></div> \n";          }while($  row = mysqli_fetch_array($  result));      } else {          echo "¡ No se ha encontrado ningún registro !";      }  ?>
