Hi all, Thank you Quanah for your answers (and Dieter too, it seems :)). This was indeed the question.

If it would, a both ways on-the-fly change based on automatic watch of the actual size of the accesslog database might be interesting if the high rate writes are a seldom event. If it wouldn't, setting a small enough interval from the beggining would do the trick.

overlay unique
by A. Schulze 14 May '19

14 May '19

Hello, I've a openldap master and numerous sync replica servers running. I'm suspect my master contain mail attributes that aren't unique. My idea was to build an other sync replica with unique overlay enabled. The 'empty' sync replica will fetch data from master and complain about values that aren't unique. I would discard that replica, correct the master database and start replication again until replication succeed. But then there was reality :-/ I placed an deliberately none-unique value in my database but replication did not fail. The replica did contain two DNs with "mail=none-unique(a)example.test". syncrepl.conf: moduleload mdb.la moduleload unique.la database mdb suffix ou=test ... overlay unique uniqiue_uri ldap:///ou=test?mail?sub? index ... limits ... syncrepl rid=1 privider=ldap://master.example ... access ... Q: is this setup wrong? Q: is replication the right way to enforce uniqueness? Looks like the answer is "no" Q: what is "the" better way? Andreas

accesslog database: overflow or data rotation?
by Manuela Mandache 14 May '19

14 May '19

Hi all, A directory is configured as delta-syncrepl provider, the backends for the main database and the accesslog database are both mdb. Everything works fine, my question is: What happens if there are so many write ops that the size of the accesslog database reaches the value of olcDbMaxSize defined for this database? Thanks! Cheers, Manuela

Hi Quanah, Thank for your answer. I improved my configuration with your indications. Unfortunately the behavior remained the same. Following your suggestions, i will send an message to ITS. I willl try to script the exact steps i did for get the current behavior. i will reuse the logs that i putted here.

Problem with N-Way multimaster replication after an node fail and restore
by David Tello 13 May '19

13 May '19

I have a problem with the N-Way replication multimaster. My enviroiment is debian Stretch and slapd (2.4.47+dfsg-3~bpo9+1) from Stretch backports. I have configured a cluster with 3 nodes. I have configured to replicate the config database and a normal data mdb database. I followed the documentation and the cluster sync work correctly when all nodes are started. If i made a change in any node, this change is replicated to the others. My problem appears when i make a change whe one node is down. In this case, the other two nodes repli correctly, and when the downed node start this get all pending changes correctly. And in this point occurs the problem. After the start of downed node, the changes mades in this node are not send to the other two nodes. For other way, the changes mades in the other two nodes (no shutdowned) are sended to all nodes correctly. I tried this config with a two nodes cluster and the behavior was the same, after reboot slapd do not send more updates. I have checked the olcServerId because i know that a mistake here can produce similar problems. I really think that it is correct. The cmdlines of the proccess are: /usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode1/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d /usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode2/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d /usr/sbin/slapd -h ldapi:/// ldap://wbsvisionNode3/ ldap://127.0.0.1/ ldaps:/// -g openldap -u openldap -F /etc/ldap/slapd.d The config database configuración is below: *DN: cn=config* ..... olcServerID: 1 ldap://wbsvisionNode1/ olcServerID: 2 ldap://wbsvisionNode2/ olcServerID: 3 ldap://wbsvisionNode3/ *dn: olcDatabase={0}config,cn=config* ....... olcMirrorMode: TRUE olcSyncUseSubentry: FALSE olcSyncrepl: {0}rid=001 provider=ldap://wbsvisionNode1 bindmethod=simple binddn="cn=admin,cn=config" credentials="TuoDqAG7UbCJx8H8gfMO" starttls=no tls_cert=/etc/pki/certs/wbsagnitio.local.es.pem tls_key=/etc/pki/private/wbsagnitio.local.es.key tls_cacert=/etc/pki/certs/wbsagnitio-ca.pem tls_reqcert=never searchbase="cn=config" scope=sub type=refreshAndPersist retry="5 5 300 +" {1}rid=002 provider=ldap://wbsvisionNode2 bindmethod=simple binddn="cn=admin,cn=config" credentials="TuoDqAG7UbCJx8H8gfMO" starttls=no tls_cert=/etc/pki/certs/wbsagnitio.local.es.pem tls_key=/etc/pki/private/wbsagnitio.local.es.key tls_cacert=/etc/pki/certs/wbsagnitio-ca.pem tls_reqcert=never searchbase="cn=config" scope=sub type=refreshAndPersist retry="5 5 300 +" {2}rid=003 provider=ldap://wbsvisionNode3 bindmethod=simple binddn="cn=admin,cn=config" credentials="TuoDqAG7UbCJx8H8gfMO" starttls=no tls_cert=/etc/pki/certs/wbsagnitio.local.es.pem tls_key=/etc/pki/private/wbsagnitio.local.es.key tls_cacert=/etc/pki/certs/wbsagnitio-ca.pem tls_reqcert=never searchbase="cn=config" scope=sub type=refreshAndPersist retry="5 5 300 +" FALSE ------ *dn: olcOverlay={0}syncprov,olcDatabase={0}config,cn=config* objectClass: olcSyncProvConfig objectClass: olcOverlayConfig olcOverlay: {0}syncprov olcSpCheckpoint: 1000 1 The data database configuración is below: *dn: olcDatabase={1}mdb,cn=config* objectClass: olcMdbConfig objectClass: olcDatabaseConfig olcDatabase: {1}mdb ... olcDbIndex: objectClass eq olcDbIndex: entryCSN eq ... olcLastMod: TRUE olcSuffix: dc=local,dc=es ......... olcMirrorMode: TRUE olcSyncrepl: {0}rid=004 provider=ldap://wbsvisionNode1 bindmethod=simple binddn="cn=manager,dc=local,dc=es" credentials="test" starttls=no searchbase="dc=local,dc=es" scope=sub type=refreshAndPersist retry="5 5 300 +" olcSyncrepl: {1}rid=005 provider=ldap://wbsvisionNode2 bindmethod=simple binddn="cn=manager,dc=local,dc=es" credentials="test" starttls=no searchbase="dc=local,dc=es" scope=sub type=refreshAndPersist retry="5 5 300 +" olcSyncrepl: {2}rid=006 provider=ldap://wbsvisionNode3 bindmethod=simple binddn="cn=manager,dc=local,dc=es" credentials="test" starttls=no searchbase="dc=local,dc=es" scope=sub type=refreshAndPersist retry="5 5 300 +" olcSyncUseSubentry: FALSE dn: olcOverlay={0}dynlist,olcDatabase={1}mdb,cn=config objectClass: olcDynamicList objectClass: olcOverlayConfig olcOverlay: {0}dynlist olcDlAttrSet: {0}virtualGroup memberDnURL uniqueMember olcDlAttrSet: {1}virtualGroup memberUidURL memberUid:uid olcDlAttrSet: {2}virtualGroup memberSidURL sambaSIDList:sambaSID dn: olcOverlay={1}lastbind,olcDatabase={1}mdb,cn=config objectClass: olcLastBindConfig objectClass: olcOverlayConfig olcOverlay: {1}lastbind olcLastBindPrecision: 30 dn: olcOverlay={2}unique,olcDatabase={1}mdb,cn=config objectClass: olcUniqueConfig objectClass: olcOverlayConfig olcOverlay: {2}unique olcUniqueAttribute: uid olcUniqueAttribute: uidNumber olcUniqueAttribute: employeeNumber olcUniqueBase: dc=local,dc=es dn: olcOverlay={3}memberof,olcDatabase={1}mdb,cn=config objectClass: olcMemberOf objectClass: olcOverlayConfig olcOverlay: {3}memberof olcMemberOfDangling: ignore olcMemberOfGroupOC: groupOfUniqueNames olcMemberOfMemberAD: uniqueMember olcMemberOfMemberOfAD: memberOf olcMemberOfRefInt: TRUE dn: olcOverlay={4}accesslog,olcDatabase={1}mdb,cn=config objectClass: olcAccessLogConfig objectClass: olcOverlayConfig olcAccessLogDB: cn=accesslog olcOverlay: {4}accesslog olcAccessLogOld: (|(objectClass=wbsagnitioGroup)(objectClass=wbsagnitioAccou nt)) olcAccessLogOldAttr: roles olcAccessLogOldAttr: objectClass olcAccessLogOps: writes olcAccessLogOps: bind olcAccessLogPurge: 7+00:00 1+00:00 dn: olcOverlay={5}ppolicy,olcDatabase={1}mdb,cn=config objectClass: olcPPolicyConfig objectClass: olcOverlayConfig olcOverlay: {5}ppolicy olcPPolicyDefault: cn=0-default,ou=passwordpolicies,ou=configuration,dc=loca l,dc=es olcPPolicyForwardUpdates: FALSE olcPPolicyHashCleartext: FALSE olcPPolicyUseLockout: FALSE dn: olcOverlay={6}syncprov,olcDatabase={1}mdb,cn=config objectClass: olcSyncProvConfig objectClass: olcOverlayConfig olcOverlay: {6}syncprov olcSpCheckpoint: 1000 1 Below i show the sync log of some operations to show the behavior of my cluster: TEST 1: 3 Nodes up.

slapindex vs reimport debug messages (mdb_index_read: failed (-30798))
by John Holder 10 May '19

10 May '19

Greetings OpenLDAP List! I have a quick question about the context and meaning of messages which show when using slapd debug and how/whether they impact indexes and performance. I recently ran into an issue where an attribute was not indexed, so I applied an index using #slapindex -F (config) (atr) When starting the daemon in debug mode and doing a search, there are many entries regarding mdb equality and index failure (see below) However, if I re-import the data using slapadd, and run the same search, all of those messages go away. I was hoping someone could assist with the meaning of the messages and why does it print the messages even after slapindex was run, but not if the olcDbIndex is added and then the ldif is re-imported? In particular I'm seeing : 5ccb5ed0 <= mdb_index_read: failed (-30798) and it seems to then search all attributes within the candidates. But this doesn't occur if the data is reimported using slapadd. Thank you! jh Debug from before export but after slapindex (key) was run: 5ccb5ed0 connection_get(13): got connid=1004 5ccb5ed0 connection_read(13): checking for input on id=1004 ber_get_next ber_get_next: tag 0x30 len 52 contents: 5ccb5ed0 op tag 0x60, time 1556831952 <callto:1556831952> ber_get_next 5ccb5ed0 conn=1004 op=1 do_bind ber_scanf fmt ({imt) ber: ber_scanf fmt (m}) ber: 5ccb5ed0 >>> dnPrettyNormal: <uid=jbh,cn=esx,cn=net> 5ccb5ed0 <<< dnPrettyNormal: <uid=jbh,cn=esx,cn=net>, <uid=jbh,cn=esx,cn=net> 5ccb5ed0 do_bind: version=3 dn="uid=jbh,cn=admins,cn=esx" method=128 5ccb5ed0 mdb_dn2entry("uid=jbh,cn=admins,cn=esx") 5ccb5ed0 => mdb_dn2id("uid=jbh,cn=admins,cn=esx") 5ccb5ed0 <= mdb_dn2id: got id=0x3 5ccb5ed0 => mdb_entry_decode: 5ccb5ed0 <= mdb_entry_decode 5ccb5ed0 do_bind: v3 bind: "uid=jbh,cn=admins,cn=esx" to "uid=jbh,cn=admins,cn=esx" 5ccb5ed0 send_ldap_result: conn=1004 op=1 p=3 5ccb5ed0 send_ldap_response: msgid=5 tag=97 err=0 ber_flush2: 14 bytes to sd 13 5ccb5ed0 connection_get(13): got connid=1004 5ccb5ed0 connection_read(13): checking for input on id=1004 ber_get_next ber_get_next: tag 0x30 len 72 contents: 5ccb5ed0 op tag 0x63, time 1556831952 <callto:1556831952> ber_get_next 5ccb5ed0 conn=1004 op=2 do_search ber_scanf fmt ({miiiib) ber: 5ccb5ed0 >>> dnPrettyNormal: <cn=servers,cn=esx> 5ccb5ed0 <<< dnPrettyNormal: <cn=servers,cn=esx>, <cn=servers,cn=esx> ber_scanf fmt ({mm}) ber: ber_scanf fmt ({M}}) ber: 5ccb5ed0 ==> limits_get: conn=1004 op=2 self="uid=jbh,cn=admins,cn=esx" this="cn=servers,cn=esx" 5ccb5ed0 => mdb_search 5ccb5ed0 mdb_dn2entry("cn=servers,cn=esx") 5ccb5ed0 => mdb_dn2id("cn=servers,cn=esx") 5ccb5ed0 <= mdb_dn2id: got id=0xd 5ccb5ed0 => mdb_entry_decode: 5ccb5ed0 <= mdb_entry_decode 5ccb5ed0 search_candidates: base="cn=servers,cn=esx" (0x0000000d) scope=2 5ccb5ed0 => mdb_equality_candidates (objectClass) 5ccb5ed0 => key_read 5ccb5ed0 <= mdb_index_read: failed (-30798) 5ccb5ed0 <= mdb_equality_candidates: id=0, first=0, last=0 5ccb5ed0 => mdb_equality_candidates (cn) 5ccb5ed0 => key_read 5ccb5ed0 <= mdb_index_read 1 candidates 5ccb5ed0 <= mdb_equality_candidates: id=1, first=33, last=33 5ccb5ed0 mdb_search_candidates: id=1 first=33 last=33 5ccb5ed0 => mdb_entry_decode: 5ccb5ed0 <= mdb_entry_decode 5ccb5ed0 => send_search_entry: conn 1004 dn="cn=esxi-master.johnholder.net ,cn=servers,cn=esx" ber_flush2: 5545 bytes to sd 13esx 5ccb5ed0 <= send_search_entry: conn 1004 exit. 5ccb5ed0 send_ldap_result: conn=1004 op=2 p=3 5ccb5ed0 send_ldap_response: msgid=6 tag=101 err=0 ber_flush2: 14 bytes to sd 13 5ccb5ed0 slap_listener_activate(7): 5ccb5ed0 >>> slap_listener(ldap://host.esx.local:389) 5ccb5ed0 connection_get(14): got connid=1005 5ccb5ed0 connection_read(14): checking for input on id=1005 ber_get_next ber_get_next: tag 0x30 len 29 contents: 5ccb5ed0 op tag 0x77, time 1556831952 <callto:1556831952> ber_get_next 5ccb5ed0 conn=1005 op=0 do_extended ber_scanf fmt ({m) ber: 5ccb5ed0 send_ldap_extended: err=0 oid= len=0 5ccb5ed0 send_ldap_response: msgid=1 tag=120 err=0 ber_flush2: 14 bytes to sd 14 <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

Unix groups information in LDAP server
by JC 10 May '19

10 May '19

I am a complete rookie when it comes to LDAP, so my apologies if what I am about to ask is something obvious. I have an LDIF file that contains entries like the following: # someuser, individuals, mydomain.comdn: uid=someuser,ou=individuals,dc=mydomain,dc=comuid: someusercn: someuserobjectClass: accountobjectClass: posixAccountloginShell: /bin/bashuidNumber: 1000gidNumber: 100homeDirectory: /home/someuser When used in conjunction with NSS in a Linux box, this allows me to centralize a number of Linux attributes for users - a specific one here called 'someuser'. The next thing I would like to do is to store information in the LDAP server about other groups that someuser belongs to. For example, besides 'users' (GID 100) someuser might belong to 'power' (GID 84) , 'mysql' (GID 27) and 'cdrom' (GID 19). Can anybody please point me in the right direction how to pull this off?

Issue with OpenLDAP as a proxy to multiple Windows DCs backends
by David Sanchez Herrero 10 May '19

10 May '19

Hello all, I'm having an issue with the configuration of an OpenLDAP working as a proxy to various Active Directory backends. The OpenLDAP proxy is in our network and we have various VPN to connect it to the remote Windows Domain Controllers (5 remote Domain Controlers of different customers, each one managing it's own domain). To configure the proxy, we use de META database. When all the Domain Controllers are up, everything works fine, but when one of then goes down (network problems, a machine reboot, etc.), the web app that uses the OpenLDAP proxy stops autheticating all users of all domains. The system process it's even hanged and when you try to stop or restart the service, it takes a long time to respond. I can't find a way to force a short timeout to ignore the offline DC and let the users of the other domains to continue working. The server OS is CentOS Linux release 7.4.1708 (Core), and the OpenLDAP version 2.4.44. To check if this is an issue of this old version, I have deployed another server with Fedora 30 and OpenLDAP 2.4.47, but same behaviour, so it's probably a configuration problem. Below are the slapd.conf file I'm using (with no private data). Any ideas about what to change in the configuration file? Thanks in advance and best regards, David. # # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. # Include /etc/openldap/schema/core.schema Include /etc/openldap/schema/corba.schema Include /etc/openldap/schema/cosine.schema Include /etc/openldap/schema/duaconf.schema Include /etc/openldap/schema/dyngroup.schema Include /etc/openldap/schema/inetorgperson.schema Include /etc/openldap/schema/java.schema Include /etc/openldap/schema/misc.schema Include /etc/openldap/schema/nis.schema Include /etc/openldap/schema/openldap.schema Include /etc/openldap/schema/collective.schema Include /etc/openldap/schema/pmi.schema Include /etc/openldap/schema/ppolicy.schema allow bind_v2 # Define global ACLs to disable default read access. # Do not enable referrals until AFTER you have a working directory # service AND an understanding of referrals. #referral ldap://root.openldap.org pidfile /var/run/openldap/slapd.pid argsfile /var/run/openldap/slapd.args # Load dynamic backend modules: modulepath /usr/lib64/openldap moduleload rwm.la moduleload back_meta.la moduleload back_ldap.la moduleload back_null.la moduleload back_bdb.la moduleload back_hdb.la moduleload back_ldif.la moduleload back_shell.la moduleload back_perl.la loglevel 4095 ####################################################################### # MDB database definitions ####################################################################### ###Ad Principal database meta suffix "dc=ldapproxy-pre,dc=local" rootdn "cn=manager,dc=ldapproxy-pre,dc=local" rootpw ?????????????? chase-referrals no nretries 0 ################################### # # Entrada LDAP para ONE # ################################### uri "ldap://1.2.3.1/ou=ONE,ou=Usuarios,dc=ldapproxy-pre,dc=local" readonly yes lastmod off suffixmassage "ou=ONE,ou=Usuarios,dc=ldapproxy-pre,dc=local" "dc=ONE,dc=local" idassert-bind bindmethod=simple binddn="CN=USERONE,OU=Usuarios,DC=ONE,DC=local" credentials="??????????????" mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=manager,dc=ldapproxy-pre,dc=local" overlay rwm rwm-map attribute uid mail ################################### # # Entrada LDAP para TWO # ################################### uri "ldap://1.2.3.2/ou=TWO,ou=Usuarios,dc=ldapproxy-pre,dc=local" readonly yes lastmod off suffixmassage "ou=TWO,ou=Usuarios,dc=ldapproxy-pre,dc=local" "ou=TWO,ou=people,ou=users,dc=TWO,dc=local" idassert-bind bindmethod=simple binddn="CN=USERTWO,CN=Users,DC=TWO,DC=local" credentials="????????????" mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=manager,dc=ldapproxy-pre,dc=local" overlay rwm ################################### # # Entrada LDAP para THREE # ################################### uri "ldap://1.2.3.3/ou=THREE,ou=Usuarios,dc=ldapproxy-pre,dc=local" readonly yes lastmod off suffixmassage "ou=THREE,ou=Usuarios,dc=ldapproxy-pre,dc=local" "dc=THREE,dc=red" idassert-bind bindmethod=simple binddn="CN=USERTHREE,CN=Users,DC=THREE,DC=red" credentials="??????????????????????" mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=manager,dc=ldapproxy-pre,dc=local" overlay rwm ########################################## # # Entrada LDAP para FOUR # ######################################### uri "ldap://1.2.3.4/ou=FOUR,ou=Usuarios,dc=ldapproxy-pre,dc=local" readonly yes lastmod off suffixmassage "ou=FOUR,ou=Usuarios,dc=ldapproxy-pre,dc=local" "dc=FOUR,dc=loc" idassert-bind bindmethod=simple binddn="CN=USERFOUR,CN=Users,DC=FOUR,DC=loc" credentials="??????????????????????" mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=manager,dc=ldapproxy-pre,dc=local" overlay rwm ################################### # # Entrada LDAP para FIVE # ################################### uri "ldap://1.2.3.5/ou=FIVE,ou=Usuarios,dc=ldapproxy-pre,dc=local" readonly yes lastmod off suffixmassage "ou=FIVE,ou=Usuarios,dc=ldapproxy-pre,dc=local" "dc=FIVE,dc=local" idassert-bind bindmethod=simple binddn="CN=USERFIVE,CN=Users,DC=FIVE,DC=local" credentials="???????????????????" mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=manager,dc=ldapproxy-pre,dc=local" overlay rwm
