Hello, I'm trying to accomplish Multi-Master OpenLDAP Replication for 3 nodes, but it's not working. Specifically, per The OpenLDAP 2.4 Administrator's Guide, Section 18.3.3 "N-Way Multi=Master", I have created the following LDIF file and slapd.conf file, but when I run slapadd to create my config database it fails. Could you please advise? Thank you very much.

How to force password change upon account creation
by Kyle Harris 24 Dec '12

24 Dec '12

Hello All, I have a perl script that allows for the creation of new accounts in OpenLDAP. I am attempting to find a way to force the newly created user to change his or her password upon first login. I tried setting the attribute pwdMustChange to TRUE but that attribute must not be definable upon user creation. So, how can this be accomplished so that a new user is forced to change passwords after they first log on? Thank you.

Hi We are planing migration from openldap 2.4.20 (with bdb 4.8) to openldap 2.4.33 (bdb 5.1.29) No of users are 4 million and about to go live within next 10 days. We are using flat file for configuration in use. Below is my slapd.conf and DB_CONFIG files include /apps/openldap/etc/openldap/schema/core.schema include /apps/openldap/etc/openldap/schema/cosine.schema include /apps/openldap/etc/openldap/schema/nis.schema include /apps/openldap/etc/openldap/schema/inetorgperson.schema include /apps/openldap/etc/openldap/schema/openldap.schema include /apps/openldap/etc/openldap/schema/dyngroup.schema include /apps/openldap/etc/openldap/schema/ppolicy.schema include /apps/openldap/etc/openldap/schema/channelIdentifier.schema include /apps/openldap/etc/openldap/schema/platform.schema include /apps/openldap/etc/openldap/schema/extendedProfileKey.schema include /apps/openldap/etc/openldap/schema/extendedProfileValue.schema include /apps/openldap/etc/openldap/schema/behaviorKey.schema include /apps/openldap/etc/openldap/schema/behaviorValue.schema include /apps/openldap/etc/openldap/schema/questionAnswer.schema include /apps/openldap/etc/openldap/schema/extendedTop.schema include /apps/openldap/etc/openldap/schema/counter.schema pidfile /apps/openldap/var/run/slapd.pid argsfile /apps/openldap/var/run/slapd.args logfile /apps/logs/ldap loglevel 16640 database bdb suffix "dc=ibm,dc=com" access to attrs=userPassword by self write by anonymous auth by * break access to * by group/groupOfUniqueNames/uniqueMember.exact="cn=VWrite,ou=businessUsersGroup,dc=ibm,dc=com" manage by group/groupOfUniqueNames/uniqueMember.exact="cn=VRead,ou=businessUsersGroup,dc=ibm,dc=com" read by * break access to * by self write by anonymous auth by * read rootdn "cn=Manager,dc=ibm,dc=com" rootpw {SSHA}dXDFSQeFjSoa/A1HfJ3TAzYf8 ################## SSL ########################################## # #TLSVerifyClient allow TLSCipherSuite HIGH:MEDIUM:+SSLv3 TLSCACertificateFile /apps/openldap/etc/openldap/cacerts/nascarcacert.pem TLSCertificateFile /apps/openldap/etc/openldap/cacerts/sj.crt TLSCertificateKeyFile /apps/openldap/etc/openldap/cacerts/sj.key # index entryCSN eq index entryUUID eq index mail,uid,postalCode,smail,channelType,channelValue,answer,behavName,objectclass,tokenID,type eq index givenName,sn,city,question,behavValue,cn,extName sub index displayName approx overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 serverid 3 syncrepl rid=111 provider=ldap://mmprod04 binddn="cn=Manager,dc=ibm,dc=com" bindmethod=simple starttls=yes tls_reqcert=allow credentials=G00gle# searchbase="dc=ibm,dc=com" type=refreshAndPersist retry="5 5 300 +" interval=00:00:00:10 syncrepl rid=222 provider=ldap://mmprod05 binddn="cn=Manager,dc=ibm,dc=com" bindmethod=simple starttls=yes tls_reqcert=allow credentials=G00gle# searchbase="dc=idm,dc=com" type=refreshAndPersist retry="5 5 300 +" interval=00:00:00:10 mirrormode TRUE cachesize 100000 idlcachesize 300000 lastmod on checkpoint 128 15 concurrency 100 directory /apps/openldap/var/openldap-data overlay unique unique_attributes mail overlay ppolicy ppolicy_default "cn=default,ou=pwdPolicy,dc=idm,dc=com" ppolicy_use_lockout DB_CONFIG set_cachesize 0 4294967295 0 set_lg_regionmax 2048576 set_lg_max 20485760 set_lg_bsize 2097152 set_lk_max_locks 10000 set_lk_max_objects 5000 set_lk_max_lockers 5000 My querries are:- 1.

Config dynamic list using slapd.d
by vitdua 24 Dec '12

Hi all, I have managed to make Openldap to use dynamic list. Luckily, I found this http://koivunej.wordpress.com/2012/07/16/learning-openldap-2-4-cnconfig-usa… and config LDAP successfully. But I also need to config *member-attr*: overlay dynlist dynlist-attrset groupOfURLs labeledURImember image as in OpenLDAP document. Could you show me way to do it with OLC (cn=config)? Thanks, Viet

Why ldapsearch is not working with anonymous bind after upgrading OpenLDAP to v2.4?
by Sachin Divekar 23 Dec '12

23 Dec '12

Dear all, I have a setup of **OpenLDAP v2.3** which I am using for last few years. Following are the lines in `slapd.conf` for access control. access to dn.one="o=abc, c=IN" by * read access to dn.base="o=abc, c=IN" by * none When I do ldapsearch using anonymous bind gives me result. For example following command gives result. ldapsearch -x -h localhost -b "o=abc,c=IN" Now I upgraded the OS, CentOS from 5.5 to 6.3 so the version of OpenLDAP is **OpenLDAP v2.4**. We have not changed the schema. But now the same `ldapsearch` gives me `result: 32 No such object` error. But it works when I added following line in access control configuration. access to dn.one="o=abc, c=IN" by * read access to dn.base="o=abc, c=IN" by anonymous read by * none What can be the reason? Is there any security risk in doing so? Thank you. -- Regards, Sachin Divekar
