Dovecot can't read mail, creates duplicate directories

[John Oliver]

CentOS 6.5, dovecot 2.0.9-7

I used http://www.linuxmail.info/postfix-dovecot-ldap-centos-5/ to
configure LDAP authentication for postfix and dovecot.

I can log in to dovecot via IMAP, but it cannot read messages.  It does
wind up creating alternate directories though:
