Separate trees openldap
by seguranca informacao 01 May '18

01 May '18

Hi guys, I'm trying to accomplish a configuration that I'm not aware of. I need to replicate several directories (AD, openldap, etc) to a unique repository (my openldap). The thing is I need to have completely separate trees for each domain (client). Any ideas in how to do that? bellow is an example what I'm thinking of: dc=example,dc=com cn=users cn=groups ------------------------------ complete separation dc=domain,dc=com cn=users cn=groups ------------------------------ complete separation dc=test,dc=ca cn=users cn=groups ------------------------------ complete separation thx, sergio

Hello All! I have started building a large scale OpenLDAP infrastructure for the company I work for and Im running into one issue i cant seem to resolve. The final architecture is 4 Master servers (each one in its own data center across the USA) We also want to have 2 slaves tied to each master. We deal with an incredibly high amount of authentication traffic. I currently have the 4 masters configured (n-master - using syncrepl) that is functioning as designed, cn=config and user databases are successfully replicated across the 4 servers no matter which server you use to update. What I am having issues with is getting the slaves to sync to the masters. I have the rpuser set up, the machines can talk to each other. I can run queries using the rpuser from any slave to any master and get data back. I can see the rpuser connecting to the master, and showing successful authentication in an attempt to replicate back to the slave. But this error comes up do_syncrep2: rid=010 got search entry without Sync State control and user data is not replicated back to the slave. some additional notes: On the slaves, i did NOT replicate the cn=config db {0) only the here is the LDIF file (with hostnames/passwd removed) dn: olcDatabase={1}mdb,cn=config changetype: modify add: olcSyncRepl olcSyncRepl: rid=010 provider=ldap://master-1.example.com:389/ bindmethod=simple binddn="uid=rpuser,dc=example,dc=com" credentials=banana searchbase="dc=example,dc=com" type=refreshAndPersist retry="30 5 300 3" interval=00:00:05:00 here is the applied config on the slave server # {1}mdb, config dn: olcDatabase={1}mdb,cn=config objectClass: olcDatabaseConfig objectClass: olcMdbConfig olcDatabase: {1}mdb olcDbDirectory: /var/lib/ldap olcSuffix: dc=squaretrade,dc=com olcAccess: {0}to attrs=userPassword by self write by anonymous auth by * none olcAccess: {1}to attrs=shadowLastChange by self write by * read olcAccess: {2}to * by * read olcLastMod: TRUE olcRootDN: cn=admin,dc=example,dc=com olcSyncrepl: {0}rid=010 provider=ldap://master-1.example.com :389/ bindmethod=simple binddn="uid=rpuser,dc=example,dc=com" credentials =banana searchbase="dc=example,dc=com" type=refreshAndPersist retry="30 5 300 3" interval=00:00:05:00 olcDbCheckpoint: 512 30 olcDbIndex: objectClass eq olcDbIndex: cn,uid eq olcDbIndex: uidNumber,gidNumber eq olcDbIndex: member,memberUid eq olcDbMaxSize: 1073741824 here is the syncprov config on the master it is communicating with # {0}syncprov, {1}mdb, config dn: olcOverlay={0}syncprov,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {0}syncprov My questions 1> does the slave also require the cn=config database replication? 2> do the masters need similar configs (i.e. like the n-master config) does RID=010 also need to be configured on the master? here is a section of logs from a sync attempt Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=9 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=10 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=11 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: =>do_syncrepl rid=010 Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=12 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=13 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: =>do_syncrep2 rid=010 Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: do_syncrep2: rid=010 got search entry without Sync State control (dc=example,dc=com) Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: do_syncrepl: rid=010 rc -1 retrying (1 retries left) Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: activity on 1 descriptor Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: activity on: Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=9 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=10 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=11 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=12 active_threads=0 tvp=zero Apr 18 09:27:36 la1-ldap-slave-prod-1 slapd[14543]: daemon: epoll: listen=13 active_threads=0 tvp=zero any assistance would be greatly appreciated! and if there is additional information that will help just ask!

OpenLDAP & Mysql backend
by Arianna Milazzo 01 May '18

01 May '18

Hello! I installed openLDAP on Debian 9 with mysql backend. I followed the guide and I used example database (http://www.openldap.org/faq/data/cache/978.html ) Now, I can connect to openldap with root credential (in slapd.conf) or with a "person" present in ldap_entries, but I don't see nothing: no search result. With Apache Directory Studio I see only organization. Even it's impossible add something: ldap_add: Server is unwilling to perform (53) additional info: operation not permitted within namingContext Please, someone can tell me why? Thanks, Arianna

mdb_del: MDB_MAP_FULL: Environment mapsize limit reached
by James Anderson 26 Apr '18

26 Apr '18

good morning; we recently observed a call to mdb_del had returned a mdb_map_full error for an environment which i believe to be configured when opened to permit 40G, while, currently stat indicates a size of roughly 1.7G on disk. i find no bug reports related to this. are there any secondary factors which would lead to this result? this is using the lmdb library at 0.9.21 --- james anderson | james(a)dydra.com | http://dydra.com

Re: slapadd not adding some of the roleoccupent entries

There are a number of them (such as entryUUID, entryCSN, etc). Regardless, for replication to work, the operational attr values must be the same across servers. This is generally why if you're bringing up replication in an environment where you already have an existing DB, you slapcat the DB off your "golden" master, and then use slapadd to import it to the other servers. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Migration Task from 2.3.x to 2.4.x
by Periko Support 24 Apr '18

24 Apr '18

Hi people. I got a centos 6.x server running openldap 2.3.x as backend or our samba domain. I need to move to centos 7 which came with openldap 2.4.x. I had read that the files settings change and need to upgrade to the new format for 2.4.x I got my ldap backups, is this the right way to do it? 1) Move my backup to the new server. 2) Remove slapd.d dir from /etc/openldap in the new installation. 3) Copy my openldap settings from the old server (/etc/openldap/) 4) run slapadd -l ldap.backup 5) create a empty directory called slapd.d /etc/openldap 6) convert to new format: slaptest -f ldap.backup -F /etc/openldap/slapd.d This is correct guys or I miss something? Thanks for your help and time!!!

This will not work, because your skeleton is missing the required operational attrs. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

removing ppolicy overlay
by Frank Swasey 16 Apr '18

16 Apr '18

Is there a recommended way to discontinue the use of the ppolicy overlay? The only way I've found that works is to stop the ldap server and using slapcat/edit/slapadd eradicate all the ppolicy attributes (combined with removing the ppolicy overlay and schema from the slapd.conf file). I'm attempting this on RHEL7 with OpenLDAP 2.4.46 (local built). Thanks, - Frank
