I've trying to get dovecot-auth to talk to exim and have been running
debugging on both sides.

I've added the line:

        i_info("auth_client_input: client disconnected: %s", strerror(errno));

just after the "case -1" in the first switch statement in:

        auth-client-connection.c: auth_client_input()

and get this in the logs:

dovecot: Feb 27 13:35:09 Info: auth(default): auth_client_input: client
disconnected: Illegal seek

Now, on the exim end if I don't have the i_info() call in the routine the call
to fgets() which exim is using never returns. If I put the i_info() call in
there it does and gives an error, e.g.

2007-02-27 13:35:09 dovecot_plain authenticator failed for
vanguard.earth.ox.ac.uk [163.1.22.82]: 435 Unable to authenticate at present:
authentication socket protocol error

Now, the istreams code in dovecot seems rather too obscure for me to debug any
further.

According to the read(2) man page under Solaris 10, the only version of read
which can possibly return ESPIPE is pread().

Any ideas what's going on?
