pptpd on Debian doesn't write any logs

I'm trying to set up PPTP server with Debian Squeeze.

The problem is nothing is being written in the logs (neither in messages nor in debug nor in daemon.log) though debug and dump options are set. The only line I get after pptpd restart is:

# tail -n 1 /var/log/daemon.log
Dec 21 00:25:09 vpn pptpd[1965]: MGR: Manager process started

The daemon starts, the port is listened and available to connect. But no logs... I've tried to find pptpd-dbg but debian has no such package. Any ideas on what's wrong with my config? pptpd or rsyslog ones. Is there any way to get pptpd debug output on stdout?

pptpd version 1.3.4-3 (set up from stable repository)
rsyslog version 4.6.4-2 (set up from stable repository)
