	So why is dovecot searching for uid? I am not asking it to; in fact, my
pass_attrs field is empty.
	Also, I have switched around my setup to not use auth_bind:

hosts = ldap.lrtz
dn = cn=varmail,ou=users,dc=lorentz,dc=com
dnpass = *******
ldap_version = 3
auth_bind = no
pass_attrs = userPassword=password
pass_filter = (&(objectClass=inetOrgPerson)(mail=%Lu))
base = ou=users, dc=%Dd
scope = onelevel

	With this configuration, it becomes inconsistant. Sometimes my client
authenticates, and sometimes my client goes through the same timeout as
	I have not had time to run enough trials to prove this, but it seems
like this new configuration works for the first connection made to
dovecot, and then times out on subsequent connections.  If I restart
dovecot, then I get one successful connection again, and then the others
	I am not certain on this, however.  I seem to remember the first
connection timing out on one run...
