sync_client and ptloader

[cyrus at univ-paris4.fr]

Hi,

I get a "connection refused" when i try to enable sync_client with 
ptloader. I use cyrus-imapd-2.3.9

sync_client[13982]: ptload(): pinging ptloader
sync_client[13982]: ptload(): can't connect to ptloader server: 
Connection refused
kernel: Dec 13 17:32:11 sacco sync_client[13982]: ptload(): can't 
connect to ptloader server: Connection refused
sync_client[13982]: No data available at all from ptload()
sync_client[13982]: ptload completely failed: unable to canonify 
identifier: sync


in cyrus.conf

ptloader       cmd="ptloader" listen="/var/imap/socket/ptsock" prefork=1

in imapd.conf

ptloader_sock: /var/imap/socket/ptsock

ls -al /var/imap/socket/ptsock
srwxrwxrwx  1 root  mail  0 Dec 13 15:44 /var/imap/socket/ptsock
