Authentication failed.

Hi,

I installed openldap22 with courier-imap, courier-auth-lib and postfix
22 in freebsd 5.4. But when I test pop3, I got the following error in
the log:

May 30 12:05:52 mail02 postfix/postfix-script: starting the Postfix mail
system
May 30 12:05:53 mail02 postfix/master[7678]: daemon started -- version
2.2.3, configuration /usr/local/etc/postfix
May 30 12:06:51 mail02 authdaemond: authldaplib: error in LDAP
configuration file, aborting
May 30 12:06:51 mail02 pop3d: LOGIN FAILED, user=test@authtec.com, ip=[::1]
May 30 12:06:51 mail02 pop3d: authentication error: Input/output error

How can I track down the problem in detail?

Thanks
Sam
