Question postfix+dovecot in rhel6.1 not getting local mails


Hi,
I am trying to configure postfix+dovecot+squirrelmail and user will get authenticated with openldap. I am not able to send mails even locally.

[root@mail ~]# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases, ldap:/etc/postfix/ldap-aliases.cf
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
home_mailbox = Maildir/
html_directory = no
inet_interfaces = all
inet_protocols = all
mail_owner = postfix
mail_spool_directory = /var/spool/mail
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = 172.16.23.0/24, 127.0.0.0/8, $myhostname, localhost.$mydomain, localhost, $mydomain, mail.cseb.gov.in
mydomain = cseb.gov.in
myhostname = mail.cseb.gov.in
mynetworks = 172.16.23.0/24, 127.0.0.0/8
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
relay_domains = $mydestination
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_banner = $banner
smtpd_sasl_type = dovecot
unknown_local_recipient_reject_code = 550
==================

Jul 6 07:23:13 mail postfix/qmgr[4464]: 1CD298008D1: from=<root@cseb.gov.in>, si ze=426, nrcpt=1 (queue active)
Jul 6 07:23:13 mail postfix/local[22357]: warning: dict_ldap_lookup: /etc/postfi x/ldap-aliases.cf: Search base 'o=cseb' not found: 32: No such object
Jul 6 07:23:13 mail postfix/local[22357]: 1CD298008D1: to=<root@cseb.gov.in>, re lay=local, delay=0.09, delays=0.07/0.01/0/0.01, dsn=4.3.0, status=deferred (alias database unavailable)


Expert advice required to come out this issue.

Thanks,
Shanakr

so the log there clearly states an LDAP issue, no such object looking for o=seb...

Hi Chris,

[root@mail ~]# ldapsearch -x -b "cn=Manager,o=cseb"
# extended LDIF
#
# LDAPv3
# base <cn=Manager,o=cseb> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 32 No such object

# numResponses: 1

user will get authenticate via openldap. I am not able to find the exact issue in ldap.

Thanks,
Shankar

well you haven't set up openldap... notably I can't see a domain, should you not be looking for "cn=Manager,o=seb,dc=example,dc=com"?

schemas - you already opened a new thread for that.

Postfix - there is no error there.
