by Vijay Kumar 30 Jan '20

30 Jan '20

Hi Team, >From my Java Program i am in need to find the LDAP Server version. i am able to get supportedLDAPVersion using below search query, LDAPSearchResults ldapSearchResults = ldapConn.search("", LDAPConnection.SCOPE_BASE, "(objectclass=*)", new String[] {"supportedLDAPVersion"}, false); No results found, when i try to use vendorVersion and vendorName (like that queried like below) ldapSearchResults = ldapConn.search("", LDAPConnection.SCOPE_BASE, "(objectclass=*)", new String[] {"vendorVersion"}, false) is there any approach that can follow, please let me know. i am need to get info as below, root@docker_container:/etc/ldap/slapd.d# ldapsearch -VV ldapsearch: @(#) $OpenLDAP: ldapsearch (Jul 30 2019 16:24:19) $ Debian OpenLDAP Maintainers < pkg-openldap-devel(a)lists.alioth.debian.org> * (LDAP library: OpenLDAP *20448*)* root@docker_container:/etc/ldap/slapd.d# Thank you. -- Thanks & Regards, Vijay Kumar *+91-94944 44009*

This is the second testing call for OpenLDAP 2.4.49. Depending on the results, this may be the only testing call. Generally, get the code for RE24: <http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=snapshot;h=refs/h…> Configure & build. Execute the test suite (via make test) after it is built.

CentOS drops OpenLDAP servers package starting with 8.1
by Quanah Gibson-Mount 30 Jan '20

30 Jan '20

The CentOS project has now also elected to drop support for the OpenLDAP server package starting with 8.1: <https://bugs.centos.org/view.php?id=16959> I will note that Symas continues to offer free packages for Centos8/RHEL8 users based off of the Centos8.0 package. We will likely move this to mirror the Fedora package (which is what the CentOS package was based on). <https://symas.com/linuxopenldap/> Regards, Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

cn=config replication stops after adding olcAccess entries
by Jan Hugo Prins 28 Jan '20

28 Jan '20

Hello, I'm trying to setup a new MMR cluster. I started the installation using the documentation from: https://www.openldap.org/doc/admin24/replication.html#N-Way%20Multi-Master OS: CentOS 7.7. CentOS RPM packages OpenLDAP version 2.4.44-21 The base installation works fine, all schema's loaded etc. At first I was thinking everything was fine, until I started testing failure scenario's. When I tried to rebuild a failed node I noticed that it wouldn't be populated. cn=config was empty except for the base config and only some data was replicated. After a lot of searching I found that adding any olcAccess rules would destroy the replication. With the olcAccess lines in the config below only the schemas are replicated. When I remove all olcAccess lines all replication works. The base config I use for a node looks like this: dn: cn=config objectClass: olcGlobal cn: config olcServerID: 1 ldap://ldap01.internal olcServerID: 2 ldap://ldap02.internal olcServerID: 3

On a server without olcAccess lines I see this, but when there are olcAccess lines I only see the configured values. All unset values are not visible. Any help is appreciated. Thank you very much.

LDAPS Multi-master replication

Hi I plan to configure Multi-master replication LDAPS on 3 servers. Are my steps correct ? 1) On each server dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: syncprov 2) On server 1 dn: cn=config changeType: modify add: olcServerID olcServerID: 1 3) On server 2 dn: cn=config changeType: modify add: olcServerID olcServerID: 2 4) On server 3 dn: cn=config changeType: modify add: olcServerID olcServerID: 3 4) On each server dn: olcDatabase={0}config,cn=config changetype: modify add: olcRootPW olcRootPW: 5fX?BLR2 5) On each server dn: cn=config changetype: modify replace: olcServerID olcServerID: 1 ldaps://infa1.domain.com olcServerID: 2 ldaps://infra2.domain.com olcServerID: 3 ldaps://infra3.domain.<ldaps://infra3.test.local>com 6) On each server dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov 7) On each server dn: olcDatabase={0}config,cn=config changetype: modify replace: olcSyncRepl olcSyncRepl: rid=001 provider=ldaps://infra1.domain.com binddn="cn=admin,cn=config" bindmethod=sasl saslmech=EXTERNAL starttls=no tls_cert="/etc/ldap/sasl2/cert.ru.crt" tls_key="/etc/ldap/sasl2/cert.ru.crt" tls_cacert="/etc/ldap/sasl2/comodo.crt" tls_reqcert=allow credentials=5fX?BLR2 searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1 olcSyncRepl: rid=002 provider=ldaps://infra2.domain.comn binddn="cn=admin,cn=config" bindmethod=sasl saslmech=EXTERNAL starttls=no tls_cert="/etc/ldap/sasl2/cert.ru.crt" tls_key="/etc/ldap/sasl2/cert.ru.crt" tls_cacert="/etc/ldap/sasl2/comodo.crt" tls_reqcert=allow credentials=5fX?BLR2 searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1 olcSyncRepl: rid=003 provider=ldaps://infra3.domain.com binddn="cn=admin,cn=config" bindmethod=sasl saslmech=EXTERNAL starttls=no tls_cert="/etc/ldap/sasl2/cert.ru.crt" tls_key="/etc/ldap/sasl2/cert.ru.crt" tls_cacert="/etc/ldap/sasl2/comodo.crt" tls_reqcert=allow credentials=5fX?BLR2 searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=1 - add: olcMirrorMode olcMirrorMode: TRUE Is this correct ?

multimaster delta syncrepl inconsistent attribute values
by Zach Hanson Hart 27 Jan '20

27 Jan '20

I am seeing inconsistent values for an attribute after conflicting writes. I mostly followed https://mishikal.wordpress.com/2019/04/23/configuring-mmr-using-delta-syncr… for the setup, and mostly followed test063-delta-multimaster from the source code for the test scenario. The problem is that when I do conflicting writes while replication is broken, after replication is restored, the entry ends up with different values for an employeeNumber but everything else the same. My cluster has 3 nodes When all is said and done, the entry looks like the following on two nodes: dn: cn=fakeentryfortesting,ou=people,dc=temple,dc=edu objectClass: inetOrgPerson cn: fakeentryfortesting sn: fakeentryfortesting givenName: fakeentryfortesting carLicense: 123-XYZ description: take two from 16 description: take two from 17 description: written on 16 description: written on 17 employeeNumber: from16 employeeType: deadwood entryCSN: 20200124200603.270449Z#000000#075#000000 entryDN: cn=fakeentryfortesting,ou=people,dc=temple,dc=edu entryUUID: 737fddce-d330-1039-89fc-4599653df8c5 hasSubordinates: FALSE modifiersName: cn=admin,dc=temple,dc=edu modifyTimestamp: 20200124200603Z createTimestamp: 20200124200419Z creatorsName: cn=admin,dc=temple,dc=edu structuralObjectClass: inetOrgPerson subschemaSubentry: cn=Subschema BUT, on one node, it has employeeNumber: from17 as the only difference. >From an earlier post, this is not expected behavior. I'm including some info here in hopes that it's enough to get a workaround. If not, I can provide whatever debugging info is needed. This is a source compiled slapd 2.4.48 running on RHEL 7.7 with a preloaded libtcmalloc.so.4. I experienced the same behavior with 2.4.45. Some gory details... -------------- Overview -------------- I initially set up a single node as standalone. I then added a small ldif to give a tree to replicate. Then, I made the node do delta multimaster. Details of this are further down. I wrote an entry and verified that it got the correct Server ID in the contextCSN. I did ldapsearch -H ldapi:// -Y external -LLL -b cn=config >config.ldif to save the resulting configuration. Then I did a slapadd of that to another fresh node with empty slapd.d and database folders. It synced the data as expected. I repeated on another node. So, I have 3 nodes with identical configurations, call them 16, 17 and 18. Replication seems to be working as expected. slapd is run with: -h ldapi:/// ldaps://pre-ldapr16.temple.edu (or pre-ldapr17 or 18, depending on the node). I verified many, many times that these are identical to what's in the olcServerID, and identical to the provider in the olcSyncrepl attribute. I'm the only one accessing these nodes right now, and certainly the only one using this test DN. ------------- TEST SCENARIO ------------- My test for this mostly follows test063-delta-multimaster. Below, $TESTDN is cn=fakeentryfortesting,ou=people,dc=temple,dc=edu. It seeds a test entry and makes sure it is the same on each node: dn: $TESTDN objectClass: inetorgperson cn: fakeentryfortesting sn: fakeentryfortesting givenName: $TESTCN description: test It breaks replication on each node by replacing the password in the olcSyncrepl values with a wrong password. Below, $X is 16, 17 or 18, depending on the node. For each of the three nodes, it applies: dn: $TESTDN changetype: modify add: description description: written on $X Then for each node it applies: dn: $TESTDN changetype: modify delete: description description: test - add: description description: take two from $X Then on 16, it applies: dn: $TESTDN changetype: modify add: carLicense carLicense: 123-XYZ - add: employeeNumber employeeNumber: from$X and on a different node it applies: dn: $TESTDN changetype: modify add: employeeType employeeType: deadwood - add: employeeNumber employeeNumber: from$X It then restores replication and checks the entry on the different nodes. ------------------ INITIAL STANDALONE CONFIG ------------------ dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/run/openldap/slapd.args olcAuthzPolicy: to olcAuthzRegexp: {0}uid=ldap/([^,]*),cn=PREKDC.TEMPLE.EDU,cn=gssapi,cn=auth $1 olcConnMaxPending: 101 olcLogLevel: stats stats2 olcPidFile: /var/run/openldap/slapd.pid olcReadOnly: FALSE olcSecurity: simple_bind=128 olcSecurity: tls=0 olcSecurity: ssf=71 olcSockbufMaxIncoming: 22143 olcSockbufMaxIncomingAuth: 16777215 olcThreads: 8 olcTLSCACertificateFile: /etc/ssl/certs/intermediate.crt olcTLSCACertificatePath: /etc/openldap/certs olcTLSCertificateFile: /etc/ssl/certs/ldap.pem olcTLSCertificateKeyFile: /etc/ssl/private/ldap.key.pem olcTLSCipherSuite: ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+ AES:RSA+AESGCM:RSA+AES:!aNULL:!MD5:!DSS:!RC4:!3DES:!eNULL:!PSK olcTLSDHParamFile: /etc/ssl/private/dhparam.bin olcTLSProtocolMin: 3.2 olcToolThreads: 2 dn: cn=module{0},cn=config objectClass: olcModuleList cn: module{0} olcModulePath: /usr/local/libexec/openldap olcModuleLoad: {0}back_mdb olcModuleLoad: {1}auditlog olcModuleLoad: {2}unique dn: cn=schema,cn=config #

Awesome! Maybe there's somethig that jumped out at you as wrong with this? Thanks for any help, Zach
