The error message is a bit garbled (obviously the Base DN is wrong) but the error is basically correct. You're trying to replicate the wrong thing from the wrong place. Setting a syncrepl consumer on the olcDatabase={1}mdb database lets you replicate the *content* of that database. To replicate the *configuration* of that database your consumer must be set where that configuration is stored. The configuration is stored in olcDatabase={0}config. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Consumer Delta Sync Lost After Provider Restarted

by thomaswilliampritchard＠gmail.com

Hi, I'm experiencing an issue between my 3 providers and multiple consumer setup and delta sync repl. We manage a primary, or active, provider and send all writes to the primary as long as it's healthy letting the two others replicate and be standby providers ready to take over in the event of a failure. All consumers replicate from all providers and all providers replicate from all providers. After the system was running healthily for over a week a standby provider was restarted. This caused my consumers to re-establish the persistent sync connection. Upon re-establishing the connection, some consumers began a sync refresh with the following message. Jun 28 18:32:55 openldap-hdb-consumer slapd[15746]: do_syncrep1: rid=003 starting refresh (sending cookie=rid=003,csn=20210331192036.214412Z#000000#000#000000;20210119225955.133811Z#000000#001#000000;20210128213906.596429Z#000000#002#000000;20210226190704.219043Z#000000#005#000000;20210412181659.152626Z#000000#065#000000;20210610231714.990702Z#000000#066#000000;20210614191744.122968Z#000000#44d#000000;20210412175600.595586Z#000000#835#000000;20210423182110.684843Z#000000#836#000000;20210331193249.570935Z#000000#ce5#000000) Jun 28 18:32:55 openldap-hdb-consumer slapd[15746]: do_syncrep2: rid=003 LDAP_RES_SEARCH_RESULT Jun 28 18:32:55 openldap-hdb-consumer slapd[15746]: do_syncrep2: rid=003 delta-sync lost sync, switching to REFRESH Jun 28 18:32:55 openldap-hdb-consumer slapd[15746]: do_syncrep2: rid=003 (4096) Content Sync Refresh Required This was re-establishing a connection with rid=003 which is "20210412175600.595586Z#000000#835#000000" (a standby system) however we have only been sending writes to server #44d# (the primary provider). We see 44d CSN is over 7 days old, beyond our providers access log period. On the consumer that did not trigger sync refresh we see Jun 28 18:32:55 openldap-hdb-consumer slapd[24439]: do_syncrep1: rid=003 starting refresh (sending cookie=rid=003,csn=20210331192036.214412Z#000000#000#000000;20210119225955.133811Z#000000#001#000000;20210128213906.596429Z#000000#002#000000;20210226190704.219043Z#000000#005#000000;20210412181659.152626Z#000000#065#000000;20210621212459.620195Z#000000#066#000000;20210621214400.407867Z#000000#44d#000000;20210412175600.595586Z#000000#835#000000;20210423182110.684843Z#000000#836#000000;20210331193249.570935Z#000000#ce5#000000) Here we see 20210621214400.407867Z#000000#44d#000000 is much more recent and did not trigger a full resync, although it is close to the 7 day threshold at this point. We notice the rid=003 835 csn is the same as the consumer experiencing the problem which makes me believe the #44d# csn being old is what causes this sync refresh. I am concerned why when the standby provider is restarted the connection is getting re-established with old provider CSNs, when I search the CSNs on the consumers they look newer than the ones used to reestablish the connection. If we restart slapd on the providers after running consumers for 7 days it seems like it will trigger a sync refresh. How can we make the consumers re-establish the connection with the most recent CSN? Replication is working as expected, just the CSNs seem to remain old in this connection message. The sync refresh behavior causes a large load on the consumers and providers spiking bind times and degrading service making this concerning for our production environment.

Ldap is up, trying to get tls working.

by John Tobin

Folks, I have openldap up, it supports vsftpd, sshd, and 5 client linux machines for remote login. I would like to get tls working. I would support either ldaps [port 636], or the tls available on port 389, I am aware of the differences in implementation, and the fact that an administrator effectively has to make a decision to support one or the other in most cases. Currently: I have slapd running configured for tls under ldap [std port 389]. I am testing it on the slapd machine, with a client on the same machine. I am pointing to the same cacertificate in slapd.d [cn=config.ldif] and ldap.conf. With that in place, and the ldap.conf below: nightmare:/etc # cat ldap.conf base dc=dark,dc=net uri ldap://nightmare.dark.net # scope sub # binddn "cn=admin,dc=dark,dc=net" # bindpw jackie bind_policy soft # The user ID attribute (defaults to uid) pam_login_attribute uid pam_lookup_policy yes pam_password exop nss_schema rfc2307bis tls_reqcert never pam_filter objectClass=posixAccount ldap_version 3 nss_map_attribute uniqueMember uniqueMember ssl start_tls tls_cacert /var/lib/ldap/cacert.pem tls_cert /var/lib/server.crt tls_key /var/lib/ldap/server.key I have run ldapsearch: nightmare:/media # ldapsearch -v -x -H ldap://nightmare.dark.net:389/ -b "dc=dark,dc=net" -Z ldap_initialize( ldap://nightmare.dark.net:389/??base ) filter: (objectclass=*) requesting: All userApplication attributes # extended LDIF # # LDAPv3 # base <dc=dark,dc=net> with scope subtree # filter: (objectclass=*) # requesting: ALL # # dark.net dn: dc=dark,dc=net dc: dark o: dark objectClass: organization objectClass: dcObject # admin, dark.net dn: cn=admin,dc=dark,dc=net objectClass: organizationalRole cn: admin # Default Policy, dark.net dn: cn=Default Policy,dc=dark,dc=net objectClass: namedObject objectClass: pwdPolicy cn: Default Policy # People, dark.net dn: ou=People,dc=dark,dc=net objectClass: organizationalUnit ou: People description: People is used in mapping the /etc/passwd entries # jtobin, People, dark.net dn: uid=jtobin,ou=People,dc=dark,dc=net uid: jtobin cn: John C.

OpenLDAP crash when defining multiple olcDbURI for chaining

by Khosrow Ebrahimpour

Hello list, I am trying to setup referral chaining in a multi-master setup. I can setup chaining to one of the masters without any problems. And I can perform a MOD operation that is then referral chased and performed on the master. However, when I define both masters the replica crashes when I do a MOD operation. Snippet of cn=config from the working example: dn: olcDatabase={1}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config objectClass: olcLDAPConfig objectClass: olcChainDatabase olcDatabase: {1}ldap olcDbStartTLS: start starttls=yes olcDbIDAssertAuthzFrom: {0}* olcDbRebindAsUser: FALSE olcDbChaseReferrals: TRUE olcDbTFSupport: no olcDbProxyWhoAmI: FALSE olcDbProtocolVersion: 3 olcDbSingleConn: FALSE olcDbCancel: abandon olcDbUseTemporaryConn: FALSE olcDbConnectionPoolMax: 16 olcDbNoRefs: FALSE olcDbNoUndefFilter: FALSE olcDbURI: ldap://ldap-m1.example.com olcDbIDAssertBind: mode=self flags=prescriptive,proxy-authz-non-critical bindmethod=simple timeout=0 network-timeout=0 binddn="cn=admin,dc=example,dc=com" credentials="secret" keepalive=0:0:0 starttls=yes tls_reqcert=allow If I change olcDbURI to either of the entries below, the replica server crashes * olcDbURI: "ldap://ldap-m1.example.com,ldap://ldap-m2.example.com" * olcDbURI: "ldap://ldap-m1.example.com ldap://ldap-m2.example.com" According to slapd-ldap(5), the URI list can be comma or space separated. I've turned on "args" and "trace" debugging to troubleshoot, but never get any errors in the logs. I only see an attempt to chase the referral followed by an immediate crash (see log snippet at the end of email). Finally, I'm running OpenLDAP 2.4.31 on Ubuntu Trusty, but was also able to replicate this same error on OpenLDAP 2.4.28 on Ubuntu Precise. Any help is much appreciated. -- Khosrow Ebrahimpour Crash Log: Sep 8 21:07:23 ldap-rep1 slapd[20947]: conn=1000 op=1 modifications: Sep 8 21:07:23 ldap-rep1 slapd[20947]: replace: givenName Sep 8 21:07:23 ldap-rep1 slapd[20947]: one value, length 1 Sep 8 21:07:23 ldap-rep1 slapd[20947]: conn=1000 op=1 MOD dn="uid=user1,ou=people,dc=example,dc=com" Sep 8 21:07:23 ldap-rep1 slapd[20947]: conn=1000 op=1 MOD attr=givenName Sep 8 21:07:23 ldap-rep1 slapd[20947]: bdb_dn2entry("uid=user1,ou=people,dc=example,dc=com") Sep 8 21:07:23 ldap-rep1 slapd[20947]: => hdb_dn2id("ou=people,dc=example,dc=com") Sep 8 21:07:23 ldap-rep1 slapd[20947]: <= hdb_dn2id: got id=0x6 Sep 8 21:07:23 ldap-rep1 slapd[20947]: => hdb_dn2id("uid=user1,ou=people,dc=example,dc=com") Sep 8 21:07:23 ldap-rep1 slapd[20947]: <= hdb_dn2id: got id=0xe Sep 8 21:07:23 ldap-rep1 slapd[20947]: entry_decode: "" Sep 8 21:07:23 ldap-rep1 slapd[20947]: <= entry_decode() Sep 8 21:07:23 ldap-rep1 slapd[20947]: send_ldap_result: conn=1000 op=1 p=3 Sep 8 21:07:23 ldap-rep1 slapd[20947]: send_ldap_result: err=10 matched="" text="" Sep 8 21:07:23 ldap-rep1 slapd[20947]: send_ldap_result: referral="ldap://ldap-m1.example.com/uid=user1,ou=people,dc=example,dc=com" Sep 8 21:07:23 ldap-rep1 slapd[20947]: >>> dnPrettyNormal: <uid=user1,ou=people,dc=example,dc=com> Sep 8 21:07:23 ldap-rep1 slapd[20947]: <<< dnPrettyNormal: <uid=user1,ou=people,dc=example,dc=com>, <uid=user1,ou=people,dc=example,dc=com> Sep 8 21:07:23 ldap-rep1 slapd[20947]: conn=1000 op=1 ldap_chain_op: ref="ldap://ldap-m1.example.com/uid=user1,ou=people,dc=example,dc=com" -> "ldap://ldap-m1.example.com" Sep 8 21:09:02 ldap-rep1 slapd[21057]: @(#) $OpenLDAP: slapd (Ubuntu) (Mar 17 2014 21:20:08) $ buildd@aatxe:/build/buildd/openldap-2.4.31/debian/build/servers/slapd

Research what 'gss_accept_sec_context' and 'res_matched' mean, since those appear to be errors returned from your krb5 library.

Re: Problem with persistent search in OpenLDAP 2.4.23

by Tom Leach

Here is the primary database definition, and it's the tree that I'm trying to run a persistent search against. I have the syncprov overlay loaded towards the end after the syncrepl and accesslog stuff. The "overlay syncprov" three lines are the only lines in slapd.conf that reference syncprov. Thanks!
