That isn't currently a supported function (search bugzilla for the RFE and vote on it), you'll currently have to write a script to synchronise the passwords.

I don't have one, there might be one in the forums if you search.

I found the below script !!! thanks...

#!/bin/bash

# This script allows the syncing of the Zimbra password database (OpenLDAP)
# with an external LDAP database (I use an external OpenLDAP) in a three step
# procedure. It's not *that* user friendly, so I hope you have some idea of
# how scripts work.
#
# The script searches (ldapsearch) whih user has changed his password in the
# last TIME seconds (i.e. TIME=300 for 5 minutes)
#
# The output passes through sed to create a correct ldif. This means adding
# the "changetype: modify" and "replace: userPassword" strings. In case your
# password filed has a different name, change the "userPassword" string in
# the sed line accordingly.
#
# Lastly, the ldapmodify command feeds the ldif created by sed to the external
# server.

# Change variables accordingly

# Time since which to search for changed passwords. i.e. TIME=300 means the
# user has changed his password in the last 5 minutes. Adjust your crontab
# accordingly, for example if you run this script every 10 minutes (instead
# of 5 like I do) change TIME to 600 (min*60)
TIME=300

# This is the address where the zimbra ldap is listening. If you have installed
# zimbra on a cluster, use the cluster IP
ZIMBRA_LDAP="ldap://cluster.mfa.gr"

# This is the basically the domain you you want to search. i.e. if you have the
# zimbra domain foo.org, enter "dc=foo,dc=org"
ZIMBRA_BASEDN="dc=room,dc=gr"

# The password to use to connect to the zimbra ldap server. The user is
# "cn=config" as this is the rootdn for the zimbra ldap, and the password
# --which you probably do not know-- can be changed by changing the file
# /opt/zimbra/conf/slapd.conf.in. Just locate the line starting with
# "rootpw" and change the string starting with "{SSHA}" with the password
# you wish to have
ZIMBRA_ROOTPW='zimbra_ldap_password'

# The address of the external ldap server
EXTERNAL_LDAP="ldaps://myldapserver.room.gr"

# The credentials to use. That is the credentials to bind to your ldap server,
# which of course you know. All it needs is to have enough access to change the
# userPassword field. It can be the rootdn
EXTERNAL_LDAP_BINDDN="cn=root,dc=room,dc=gr"

# The password to use for the aforementioned credentials. Since passwods may include
# special characters I used single quotes
EXTERNAL_LDAP_PASSWD='myldapserver_rootpw'

ldapsearch -LLLx -H "${ZIMBRA_LDAP}" -D "cn=config" -b "${ZIMBRA_BASEDN}" -w "${ZIMBRA_ROOTPW}" \
"(zimbraPasswordModifiedTime>=`date -u +%Y%m%d%H%M%SZ -d \"-${TIME} sec\"`)" userPassword | \
sed -e '/ou=people,dc=mfa,dc=gr$/achangetype: modify\nreplace: userPassword' | \
ldapmodify -x -H "${EXTERNAL_LDAP}" -D "${EXTERNAL_LDAP_BINDDN}" -w "${EXTERNAL_LDAP_PASSWD}"

The script works fine when zimbra ldap and external ldap with same BaseDN and ou.

But my zimbra ldap BaseDN is ou=people,dc=group,dc=example,dc=com
my openldap server BaseDN is ou=teacher,dc=example,dc=com

When I running the script, It always shown an error message.
ldap_modify: No such object (32)
matched DN: dc=example,dc=com

I'd search internet for 1 week, but I still can't fix it.
Someone help me to solve this problem, please!!

Sorry for my poor English.
Thanks, Shawn

Solved!!

I fix sed syntax then solved my problem.

sed -e 's/ou=people,dc=group,dc=example,dc=com/ou=teacher,dc=example,dc=com/g' | \
sed -e '/ou=teacher,dc=example,dc=com$/achangetype: modify\nreplace: userPassword' | \

Hi everyone.
I'm testing a ZCS 7.1.3 OS on Ubuntu 10.04.3 64bit, and use an external OpenLdap + Samba PDC installed on OpenSUSE 11.4 to authenticate users. The connection is fine until i found out that when user change their password in Zimbra Web UI, it doesn't auto-sync to external ldap server.

I found this thread and try the above script, firstly i have problem when the ldapsearch command execute:

ldap_bind: Invalid credentials (49)

I've used the slappasswd command to generate a SSHA encrypted password and update in the folowing part of the
/openldap-2.4.26.5z/etc/openldap/slapd.conf file:

database        bdb
suffix          "dc=homedomain,dc=org"
rootdn          "cn=Administrator,dc=homedomain,dc=org"
# Cleartext passwords, especially for the rootdn, should
# be avoid.  See slappasswd(8) and slapd.conf(5) for details.
# Use of strong authentication encouraged.
rootpw          {SSHA}p7XipDi6VJCfiUpx8XGHmwIq7tnUdXUO
# The database directory MUST exist prior to running slapd AND
# should only be accessible by the slapd and slap tools.
# Mode 700 recommended.
directory       /opt/zimbra/openldap-2.4.26.5z/var/openldap-data

In the ldapsearch command, i've tried everything like -D "cn=config", -D "cn=Administrator", -D "cn=root", -D "cn=Administrator,dc=homedomain,dc=org" but the ldap_bind error keeps show up. Then i found that when i use -D "uid=admin,ou=people,dc=homedomain,dc=org", the ldapsearch command can run without error, but nothing returned and no password is updated!

ldapsearch -LLLx -H "${ZIMBRA_LDAP}" -D "uid=admin,ou=people,dc=homedomain,dc=org" -b "${ZIMBRA_BASEDN}" -w "${ZIMBRA_ROOTPW}" \
"(zimbraPasswordModifiedTime>=`date -u +%Y%m%d%H%M%SZ -d \"-${TIME} sec\"`)"

I tried this single command and comment the 2 commands followed, but nothing returned, even when i changed the filter to "(zimbraPasswordModifiedTime>=0)" or "(zimbraPasswordModifiedTime=20111116022747Z)"
This is the exactly time string i got from the command

zimbra@zimbra:/home/administrator$ zmprov ga thanhdv zimbrapasswordmodifiedtime
# name thanhdv@homedomain.org
zimbraPasswordModifiedTime: 20111116022747Z

My ldapsearch command works normally with other normal filter "cn=*" "objectClass=*" ...

Any help please !!!!!

Sorry for my bad Eng.
Thanks, thanhdv.

I've made myself getting in trouble T_T .
Only cn=config can retrieve informations like zimbraPasswordModifiedTime.
