Hmmm. That must Linux. I can't find a src/auth on FBSD, and I don't 
know what the FBSD equivalent would be.

It doesn't crash, it hangs. 
	1 login bob secret
	* OK Waiting for authentication process to respond..
	* BYE Disconnected for inactivity.
	Connection closed by foreign host.
maillog gives no error message except mentioning that the connection 
was closed due to inactivity. I've sent the output from gdb, but it's 
very compassionate; no processes were killed during its production.

The problem above is caused by the fact that dovecot is not in the 
same subtree in LDAP registry as the user accounts. I may have to 
rethink that. If I log in as myself, I duplicate the error I get when 
I try to connect as myself from an MUA. So at least now I know how to 
do that. 

Maybe someone can tell me; is there ever any reason to log onto dovecot 
as dovecot? Should I make the dovecot user's LDAP entry available to 
dovecot?
