[Dovecot] imap: Error: net_connect_unix(/.../auth-master) failed: Invalid argument

Hi,

I'm unable to get past the subject error trying to setup dovecot 2.1.10 on FreeBSD 6.4: right after login the server closes the connection (testing with telnet)

I've tried manualy chown()ing auth-master to 666, so permission issues should be ruled out.

I'm attaching logs, config and excerpt of ktrace -id. I've built a version with debug symbols, but I don't seem to hit a breakpoint in net_connect_unix on lib/network.c

What can I look at?

tks

pica
