1.I am using

----------------------------------- -qmail 1.03 -Redhat 6.0 -courier imap 0.33 -ldap patch qmail-ldap-1.03-20000501 -openldap 1.2.7

-------------------------------------

2.I installed courier-imap software with authldap module by using "-configure --with-authldap"

3. I can use "authtest -m authdaemon userid" to find the user in ldap.

4. When I use "authtest -m authdaemon userid userpassword",it output "Authficated failure"

5. When I remove "LDAP_AUTHBIND=1" from authldaprc, it also output "Authficated failure".

The following is the content of /usr/lib/courier-imap/etc/authdaemonrc file

----------------------------------------------------------- authmodulelist="authcram authuserdb authpam authldap" daemons=5 authdaemonvar=/usr/lib/courier-imap/var/authdaemon

The following is the content of /usr/lib/courier-imap/etc/authldaprc file.

The following is the attribute of the user "webmail" in ldap entry.

APPENDIX:

1.When I use "authinfo",it output

---------------------------------------------------------- AUTHENTICATION_MODULES="authdaemon" AUTHDAEMONMODULELIST="authcram authuserdb authpam authldap" SASL_AUTHENTICATION_MODULES="LOGIN CRAM-MD5"

-----------------------------------------------------------

2.When I run " telnet 127.0.0.1 143" and the courier-imap seems ok.

3.When I run " A LOGIN username userpasswd",it says error.

4.When I use Netscape Navigator to connect 127.0.0.1:143 , it says "beacuse security reason,it will not connect the server".
