Dovecot 2 LDAP "unknown user"

[Peter Fraser]

I updated dovecot-ldap.conf.ext so that it now reads as below:

#Custom Settings
hosts = 192.168.153.143
dn = user at domain.com
dnpass = password
auth_bind = yes
auth_bind_userdn = %u at domain.com
ldap_version = 3
base = dc=rpservices,dc=com
#user_filter = (&(objectclass=person)(mail=%u))
user_filter = (&(objectclass=person)(uid=%u))
pass_filter = (&(objectclass=person)(uid=%u))
user_attrs = homeDirectory=/home/vmail/%u,uid=1002,gid=1002

When I tried to log in again using telnet 127.0.0.1 110, the error shows up
in maillog. I first tried logging in with just the username, then I tried
using username at domain.com. Using doveadm still works though.
