 In finally solved it using cookies. If someone has an LDAP directory
 server and wants some user to have features that others don't have,
 he can implement the following.

 1.- Setup a new field on the LDAP server for the users (as I don't
     want to add it for ALL users, I'm using the roomnumber field
     that was not being used). I set this to 'y' or 'n' depending
     on if I want or not that user to be able to send email with
     attachments.

 2.- Edit mailbox.php3 and add the following after the line 122
     (just after the if (!isset($plural)) $plural = false; ):

// the isset is used to prevent the LDAP search on EACH mailbox
// refresh. This way it's only done once in the first refresh
// after login.
if( !isset( $canattach ) )
{
 $ds=ldap_connect("my.ldap.server");
 if ($ds)
 {
   $r=ldap_bind($ds);
   $search="uid=" . $imp->user;
   $sr=ldap_search($ds,"cn=Correo, ou=People, o=sistemas.servicom2000",
       $search); 
   else
   {
     $info = ldap_get_entries($ds, $sr);
     if( $info[0]["roomnumber"][0] == "y" )
       SetCookie( "canattach", 'y', time()+3600 );
     else
       SetCookie( "canattach", 'n', time()+3600 );
   }
   ldap_close($ds);
 }
}


 3.- Edit login.php3 and add code to delete the cookie after
     doing the logout on line 39 after the 
     if (!isset($reason)) { $reason = 'login'; } :


     if( isset( $canattach ) )
     {
        unset( $canattach );
        SetCookie("canattach");
     }

 4.- Finally, in my case I use this to allow/disallow the 
     display of the BROWSE+ATTACH options of the composition
     page, so I edit horde/imp/template/compose/compose.inc
     and put the code that displays the BOX and buttons
     between the following if sentence:

     <? if( $canattach == 'y' ) { ?>

      // the standard code
      <input type="hidden" name="attachmentAction" value="">
      (etc...)
      <?php endif; ?>
      // end of standard code

      <?php } ?>


 This way only allowed users can attach files to messages.
 You can also control any other webmail feature that way!!! This
 would allow lots of new possibilites. In fact, you can use just
 1 ldap field (testing bits, or just using it as a options string
 where each letter reffers to a variable, as "ynnynny", where
 [0] = can attach files, [1] = can use ldap ....) to control
 different features. THat's important, as you can set IMP features
 individually at user level on IMP 2.2.x.

 PHP is quite awesome! I'm learning it while looking at IMP...
     
 Hope this was useful for anybody.
 Bye!
