samba - May 2012 - Cannot mount users home directories from a samba server

Hi,

as subject, i cannot mount users?s home directory after login on a 
client. i configured pam_mount:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE pam_mount SYSTEM "pam_mount.conf.xml.dtd">
<!--
         See pam_mount.conf(5) for a description.
-->

<pam_mount>

                 <!-- debug should come before everything else,
                 since this file is still processed in a single pass
                 from top-to-bottom -->

<debug enable="1" />

                 <!-- Volume definitions -->
<volume user="%(USER)" fstype="smbfs" 
path="//192.168.5.219/users/%(USER)" noroot="1"
server="amahoro"
mountpoint="/home/%(USER)" ssh="0" />

                 <!-- pam_mount parameters: General tunables -->
<luserconf name=".pam_mount.conf.xml" />



<!-- Note that commenting out mntoptions will give you the defaults.
      You will need to explicitly initialize it with the empty string
      to reset the defaults to nothing. -->
<mntoptions 
allow="nosuid,nodev,loop,encryption,fsck,nonempty,allow_root,allow_other"
/>
<!--
<mntoptions deny="suid,dev" />
<mntoptions allow="*" />
<mntoptions deny="*" />
-->
<mntoptions require="nosuid,nodev" />

<logout wait="0" hup="0" term="0"
kill="0" />


                 <!-- pam_mount parameters: Volume-related -->

<mkmountpoint enable="1" remove="true" />
<smbmount> smbmount </smbmount>
<smbumount> smbmount </smbumount>


</pam_mount>

but the error message is volume not found.

Could you take a look of samba and smbldap configuration files please? 
am not sure everything is ok.
