dovecot - Apr 2012 - dovecot: auth: Error: ldap(...) failed: No such object

I just installed the 2.1.3 version of dovecot.  When I telnet to my
dovecot linux server on the imap port (143) and try to login I get the
error "No [UNAVAILABLE] Temporary authentication failure" on the
telnet
display and 

dovecot: auth: Error:
ldap(bhammond_test at 131.103.212.38,128.121.121.193):
ldap_search(base=uid=bhammond_test at 131.103.212.38,ou=users,dc=aspect
filter=(&(objectClass=posixAccount)(productFeature=mail))) failed: No
such object

in the /var/log/maillog.

 

I am not familiar with ldap and I haven't been able to find anything
using google. Anyone have any ideas with the problem?

 

Thanks.
