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?
