Sorry I have a mistake, changing words: It should be like this: syncrepl rid=001 provider=ldap://10.100.130.164 type=refreshAndPersist retry="5 5 300 +" searchbase="dc=dominio" attrs="*" bindmethod=simple binddn="cn=admin,dc=dominio" credentials=secret syncrepl rid=002 provider=ldap://10.100.130.181 type=refreshAndPersist retry="5 5 300 +" searchbase="dc=dominio" attrs="*" bindmethod=simple binddn="cn=admin,dc=dominio" credentials=secret mirrormode TRUE In addition when I add "schemachecking=on" syncrinization doesn't works.

I need to make management understand. Most primers and/or SSL/TLS howtos should cover this, as it is rather essential for making certificates work. A Google search will help you :-) And please post/quote correctly, i.e. stop top-posting. It breaks context and readability.

Setting up syncrepl, replicated LDAP doesn't work
by John Oliver 25 Jul '08

25 Jul '08

On my working master server openldap-2.3.27-8 under CentOS 5, I added: overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 On the slave server openldap-2.3.27-8.el5_2.4 under CentOS 5.2, I added: syncrepl rid=123 provider=ldaps://primary-ldap-server:636 type=refreshOnly interval=01:00:00:00 searchbase="dc=mydomain,dc=com" filter="(objectClass=*)" scope=sub attrs="*" schemachecking=off bindmethod=simple binddn="cn=syncuser,dc=mydomain,dc=com" credentials=mysecret ldap started on the slave server OK, and /var/lib/ldap has all of the database files. On that server, from the command line, I can: [root@ldap2 ~]# ldapsearch -xLLL -b "dc=mydomain,dc=com" uid=joliver sn givenName cn dn: uid=joliver,ou=People,dc=mydomain,dc=com givenName: John sn: Oliver cn: John Oliver But when I point another machine at that slave server, it won't authenticate: Jul 23 03:06:28 localhost login(pam_unix)[9475]: check pass; user unknown Jul 23 03:06:28 localhost login(pam_unix)[9475]: authentication failure; logname=LOGIN uid=0 euid=0 tty=tty2 ruser= rhost= Jul 23 03:06:28 localhost login[9475]: pam_ldap: ldap_search_s No such object Jul 23 03:06:30 localhost login[9475]: FAILED LOGIN 1 FROM (null) FOR joliver, Authentication failure [root@localhost ~]# ldapsearch -H ldaps://ldap2.mydomain.com -b "dc=mydomain,dc=com" uid=joliver sn givenName cn ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed [root@localhost ~]# ldapsearch -H ldap://ldap2.mydomain.com -b "dc=mydomain,dc=com" uid=joliver sn givenName cn SASL/DIGEST-MD5 authentication started Please enter your password: ldap_sasl_interactive_bind_s: Invalid credentials (49) additional info: SASL(-13): user not found: no secret in database When using just ldap:// with ldapsearch, I don't know what password it's asking for. My LDAP password doesn't work, the LDAP admin password doesn't work, the local root password doesn't work... Here's the odd thing. When I started setting this up, the machine that's the primary (and working) LDAP server now was running fedora-ds. I set up OpenLDAP on what is now the slave server, and it worked perfectly. I slapcat'ed it, installed OpenLDAP on the primary server, and slapadded the db. I never generated any certificates on it at all, and it works perfectly. I just regenerated the cert on the slave server, but no joy. -- *********************************************************************** * John Oliver http://www.john-oliver.net/ * * * ***********************************************************************

mailHost
by Aravind Arjunan 24 Jul '08

24 Jul '08

hi, i had configured openldap in RHEL 5.1 operating system as master/slave for replication. It is working fine without any problem I had integrated openldap with my mailserver. mail server is in RHEL 5.1 OS and am using postfix. I have two mail box server in different location and two mail servers. unique users are existing in different mail servers The problem is when mail comes for a particular user it must go the respective mail box server. For that i need to mention in openldap a mailHost attribute. as you all know mailHost attribute is for specifying the location of mailbox. But in openldap misc.schema mailHoat attribute exits. When i add the misc.schema in slapd.conf file and if i add the mailHost attribute am getting error when i was restarting. And i had downloaded the qmail.schema from google and added that in schema directory as well as in slapd.conf Then i added the mailHost attribute. But when i specify the mailHost attribute as IP of my mailbox location, the mail is dropping by creating the IP as name.

Single master/multislave and passwords
by Bryan Payne 23 Jul '08

23 Jul '08

Our master is in dallas. One slave is in ohio. Our ohio users bind to their local server for speed's sake. This is obviously a problem if they change their password. Is there a way to bind locally but when it comes to updating passwords, it inform the master instead?

openLDAP, DCHP and DNS
by openLDAP 23 Jul '08

23 Jul '08

I would like to configure my openLDAP network using DHCP for my client machines. Is it necessary to have DNS names for all my clients, e.g. something.domain.com, for OpenLDAP to work properly or will it work as long as my openldap servers have fully qualified domain names?

password changing problems
by Ron Echeverri 22 Jul '08

22 Jul '08

I've set up OpenLDAP 2.4.10 and have been using phpldapadmin for user management. The machines in our QA environment are set up to allow LDAP users to log in, and they are also able to change their password via the passwd command. However, they are only able to do this once; if they attempt it again, it bounces back with "LDAP Password incorrect: try again". They are able to log out and in regardless, but passwd will not accept their password in order to change it. If the user's password is reset in phpldapadmin, again they are able to change the password once, and no more. There is no password policy configured in slapd; should there be? I have loglevel set to 296, but i'm not sure what to look for. thanks rone
