Mass mailbox import

[scool]

Hello,
following the previous thread from plesk10, we need to import about 400 mailboxes.
http://forum.parallels.com/showthread.php?208093-Mass-mailbox-import

on this thread instructions are working perfectly.
It seems that on plesk 11 different type format is needed.

i receive the following error
<errtext>Unable to find password_type node</errtext>

 

[scool]

Adding <password_type>crypt</password_type> , the script ends successfully but users cannot login.
any suggestions?
