[Dovecot] invalid credential using openldap

[Daminto Lie]

Hi,

What I have been trying to achieve is to be able to authenticate users through openLDAP while using Postfix, Dovecot as IMAP server and squirrelmail.

I keep getting the following error messages when trying to login to squirrelmail

2011-08-17 12:27:59 auth(default): Info: client in: AUTH    1    PLAIN    service=imap    secured    lip=127.0.0.1    rip=127.0.0.1    lport=143    rport=57794    resp=AGFkbWluAGFwbXg2c3Bu
2011-08-17 12:27:59 auth(default): Info: ldap(myuser,127.0.0.1): invalid credentials (given password: xxx)
2011-08-17 12:28:00 auth(default): Info: new auth connection: pid=1921
2011-08-17 12:28:01 auth(default): Info: client out: FAIL    1    user=myuser
2011-08-17 12:28:06 imap-login: Info: Aborted login (auth failed, 1 attempts): user=<myuser>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured

This seems to be trivial but I just could not figure out what else went wrong. I wonder if anyone might be able to give me a bit of help as I'm still learning my way around under linux system environment.

The following is what I have in /etc/dovecot/dovecot-slapd.conf

hosts = localhost

dn = cn=myadmin,dc=mycompany,dc=com 
dnpass = secrets

auth_bind = yes
auth_bind_userdn = cn=%u,ou=people,dc=mycompany,dc=com

ldap_version = 3

base = ou=people, dc=pbj, dc=com, dc=au

scope = subtree

user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid

user_filter = (&(objectClass=posixAccount)(uid=%u))

pass_attrs = uid=user,userPassword=password

pass_filter = (&(objectClass=posixAccount)(uid=%u))

Thank you in advance
