Re: Replication issue during performance test with MMR configuration and LastBind enabled
by Falgon 16 Oct '24

16 Oct '24

Hello, I'm working on the same project as Meheni. Thanks for your answer, we'll try version 2.6 OpenLDAP using the lastbind-precision. However we have several questions for the current version we're using. Is this a known problem and referenced somewhere? (we haven't found it) Is it normal to find no replication error logs even in stats + sync mode? We ran some tests in sequential mode (300,000 accounts one after the other) and managed to reproduce the problem. -Denis Le mer. 11 oct. 2023 à 14:11, Quanah Gibson-Mount <quanah(a)fast-mail.org> a écrit : > > > --On Tuesday, October 10, 2023 9:30 PM +0200 Ziani Meheni > <mehani06(a)gmail.com> wrote: > > > > > > > Hello, we are working on a project and we've come across a problem with > > the replication after performance testing : > > You need to use OpenLDAP 2.6 and then set the: > > lastbind-precision > > value.

Disable uniqueness for mail Attribute
by CALDEIRA JAVIEL Sandro 01 Mar '24

01 Mar '24

Hi, I have a legacy ldap instance (openlda-2.4) which has in the same redundant user info containing mail attribute among others (objectclass: inetOrgPerson) in 2 different ous (objectclass: organizationalUnit). I know it is a bad design for ldap users structure but I am not allowed to change it in a short time. When I tried to migrate this ldap database to openldap 2.6 I realize this is not possible anymore. I identified it is just related to mail attribute because if I omit mail attribute or use a different value for mail, then all data is imported properly. Error from phpldapadmin: Attribute value would not be unique This update has been or will be cancelled, it would result in an attribute value not being unique. You might like to search the LDAP server for the offending entry. (Search) warn LDIF text import Could not add object cn=*****,ou=Users,ou=TRG01,dc=***,dc=*****,dc=** LDAP said: Success Error number: 0x00 (LDAP_SUCCESS) Description: The operation completed successfully.

memberOf with groupOfNames
by Stefan Kania 01 Mar '24

01 Mar '24

Hi to all, up to now I only used: olcDlAttrSet: groupOfURLs memberURL member+memberOf@groupOfNames to dynamically add the Attribute memberOf to all members of a groupOfURLs. Is it possible to do the same with members for groupOfNames and groupOfUniqueNames? I yes, can someone please post the syntax? Stefan

All LDAP content is not replicating to Node2 with replication message 'not new enough, ignored'
by mbalakri＠opentext.com 15 Feb '24

15 Feb '24

Hello, We need some help to resolve the intermittent sync replication issue. We have configured mirror mode replication with two nodes. Node1 syncrepl {0}rid=1 provider=ldaps://AWPCISQL22.otxlab.net:6366 type=refreshAndPersist searchbase="o=otxlab.net" schemachecking=off bindmethod=simple binddn="cn=Directory Manager,o=otxlab.net" credentials=d retry="60 10 300 +" timeout=60 tls_reqcert=never tls_cacert="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCISQL22.otxlab.net-cert.cer" tls_cert="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCISQL22.otxlab.net-cert.cer" tls_key="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCISQL22.otxlab.net-key.pvk" Node2 syncrepl {0}rid=2 provider=ldaps://AWPCTHA1.otxlab.net:6366 type=refreshAndPersist searchbase="o=otxlab.net" schemachecking=off bindmethod=simple binddn="cn=Directory Manager,o=otxlab.net" credentials=d retry="60 10 300 +" timeout=60 tls_reqcert=never tls_cacert="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCTHA1.otxlab.net-cert.cer" tls_cert="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCTHA1.otxlab.net-cert.cer" tls_key="C:\Program Files\OpenText\CARS\defaultInst\certificates\AWPCTHA1.otxlab.net-key.pvk" olcMultiProvider is ON. We have tested replication and observed that inserting an entry into Node1 syncs to Node2, and adding an entry to Node2 syncs to Node1. Similarly, delete and update operations are working as expected. However, during continuous updates to Node1 (while both Node1 and Node2 are running, and operations like importing an .ldif file from JXplorer to Node1), some entries are not syncing to Node1. The replication logs show the following message: "rid=002 entry 'cn=GetCollection,cn=Method Set ISVPackage,cn=Cordys ESBServer,cn=cordys,cn=defaultInst,o=otxlab.net' csn=20231124172411.004202Z#000000#001#000000 not new enough, ignored" We created ticket 10136 to address this issue but did not identify the root cause initially. Upon analysis, we found that all entries producing the "not new enough, ignored" message are not syncing to Node2. We were previously using OpenLDAP 2.4 version, and this scenario worked correctly. However, we started noticing the issue after upgrading to OpenLDAP 2.5.13 version. Upon reviewing the syncrepl defect fixes, we identified this fix: https://git.openldap.org/openldap/openldap/-/commit/8d428f3163e56f90cb84cdd…, which appears to be causing the problem. We reverted this fix locally, rebuilt OpenLDAP, and tested it. The issue is not reproducible with the reverted fix. In summary, the basic scenario of adding entries to Node1 is not syncing to Node2 sometimes. Do you have any suggestions to avoid this issue?

The unique overlay: enforcing uniqueness in the union of trees
by Norman Gray 15 Feb '24

15 Feb '24

Greetings. How should I use the 'unique' overlay to enforce uniqueness of an attribute across two trees? I'd have thought that the following would work, to enforce uniqueness across ou=dept1 and ou=dept2, but it doesn't seem to. dn: olcOverlay=unique,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: unique olcUniqueURI: ldap:///ou=dept1,o=example?uidnumber?sub ldap:///ou=dept2,o=example?uidnumber?sub (and cf, slapd/overlays/unique.c:unique_new_domain). When I configure a server with this, and load two entities with the same uidNumber, the server doesn't object. I'm clearly misunderstanding something. The slapo-unique(5) manpage suggests that having two URIs juxtaposed like this is syntactically OK, but it doesn't make clear the semantics of this. I'd guessed that the above configuration would create a 'domain' which is the union of the two subtrees, but that doesn't seem to be the case. Another thing that such a line could potentially specify is that a tuple of attributes is unique. For example that 'olcUniqueUri: ldap:///?sn?sub ldap:///?cn?sub' specifies that (sn,cn) is unique. There's nothing in the slapo-unique manpage that would back up this interpretation, though. Or is the above configuration in fact equivalent to olcUniqueURI: ldap:///ou=dept1,o=example?uidnumber?sub olcUniqueURI: ldap:///ou=dept2,o=example?uidnumber?sub which would enforce uniqueness of uidnumber on trees ou=dept1 and ou=dept2 separately. I take it that this isn't so, because the manpage talks of multiple 'domains', each of which can have multiple URIs. In the example below, if I instead add user uid=u2,ou=dept1,o=example, then a duplicated uidNumber is indeed rejected in the ldapadd step (so the overlay is active). I see an older thread [1] on this topic, but that refers only to a single URI in the olcUniqueURI attribute. That was resolved by adding an index on the relevant attribute, but that index is included in the configuration below. (The goal here is to enforce uniqueness of uidNumber attributes in (dept1 union dept2) and (dept1 union dept3), but permit duplication in dept2 and dept3.)

ldapi issue
by chilimili1＠outlook.de 12 Feb '24

12 Feb '24

Problem: When attempting to use the ldapi:// URI to interact with the OpenLDAP server using commands like ldapmodify or ldapsearch, an error is encountered: ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1). Process is running # ps -aux |grep ldap ldap 9 0.0 0.4 42232968 79472 ? Sl Jan23 0:10 /usr/libexec/slapd -u ldap -h ldap:/// ldapi:/// ldaps:/// -F /etc/openldap/slapd.d -d 256 Troubleshooting Steps Taken: Verified the ldapi URI configuration. Inspected the OpenLDAP configuration using slapd.conf or cn=config. Examined ACLs and access control rules. Additional Information: OpenLDAP is running as a Docker container on RHEL 9 Basis OS Docker Compose configuration includes port mappings for LDAP (3269:389) and LDAPS (3268:636). The whole configuration was migrated from a working RHEL7 Server with Openladp 2.4.5. the new version in place is 2.5.13 Any additional insights or recommendations for resolving the ldapi connection issue would be greatly appreciated. Additional to this, I would like to activate pagination, but I have not been able to find any configuration for it. Is this something that needs to be done on the server or client side?

olcLimits and groupOfURLs dynlist
by Norman Gray 12 Feb '24

12 Feb '24

Greetings. I have another puzzle with my OpenLDAP configuration, where I'm not sure if what I'm seeing is unexpected. Short version: should I expect a group in an olcLimits spec to work when the group is dynamic? I have a dynamic group set up, using the dynlist overlay, which expands to a set of DNs which should be allowed slightly privileged access to a directory. That group seems to be working OK: % ldapsearch -x -H ldap://localhost:8389 -b o=example -LLL '(cn=ldap-operators)' dn: cn=ldap-operators,ou=groups,o=example cn: ldap-operators objectClass: groupOfURLs description: Members of all of the LDAP admin and tech groups memberURL: ldap:///ou=groups,o=example?member?sub?(|(cn=ldap-admins-*)(cn=ldap-techs)) member: uid=norman,ou=staff,o=example [...] One goal here is to remove query limits for this group. I can test that by adding an artificially low limit: olcLimits: group/groupOfURLs/member="cn=ldap-operators,ou=groups,o=example" size=2 If I then make a query which has a few results, I do not get this limit imposed, and instead see in the logs 65c3ce83.0f52bea8 0x16e9d3000 => mdb_entry_get: found entry: "cn=ldap-operators,ou=groups,o=example" 65c3ce83.0f533f90 0x16e9d3000 <= mdb_entry_get: failed to find attribute member (If, instead of this, I define an ldap-operators group of class groupOfNames, with the above 'member' included explicitly, and make the corresponding change to the olcLimits line, I get what I expect -- ie, a restricted-size response to the query -- which reassures me I'm not doing something stupid elsewhere.) The slapo-dynlist(5) page says: > Any time an entry with a specific objectClass is being returned, the > LDAP URI-valued occurrences of a specific attribute are expanded into > the corresponding entries, and the values of the attributes listed in > the URI are added to the original entry. I note the ‘any time’. My configuration appears to be working for the ldapsearch lookup; I don't see any text in that manpage that suggests this won't work for the (somehow internal?) lookup being done when processing the olcLimits expression. The page slapd-config(5) says, under olcLimits: > The term group, with the optional objectClass oc and attributeType at > fields, followed by pattern, sets the limits for any DN listed in the > values of the at attribute (default member) of the oc group > objectClass (default groupOfNames) whose DN exactly matches pattern. That text doesn't seem to me to exclude this entry lookup from the ‘any time’ in the slapo-dynlist text above. This is OpenLDAP 2.6.7. I am of course open to a frame-challenge about the best way of achieving the underlying goal. Best wishes, Norman -- Norman Gray : https://nxg.me.uk

Openldap 2.4 -> Openldap 2.6.3 replication hurdles
by Viktor Keremedchiev 08 Feb '24

08 Feb '24

Hello, I'm somewhat not experienced with LDAP on the server side of things I’m importing openldap 2.4. into 2.6.3. (rockylinux 9). My goal is to 2 have 2 N-way (or multi-master*) ldap nodes. I’ve changed hdb to mdb, created accesslog folder, fixed permissions, SSL etc The import doesn’t throw any errors. My understanding is that I need to have cn=config replication, as well as my small dc=domain,dc=com, replication as well The cn=config replication I call via this on both nodes followed by restarts dn: cn=config changetype: modify replace: olcServerID olcServerID: 1 dn: olcOverlay=syncprov,olcDatabase={0}config,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov olcSpNoPresent: TRUE olcSpReloadHint: TRUE dn: olcDatabase={0}config,cn=config changetype: modify replace: olcSyncRepl olcSyncRepl: rid=002 provider=ldaps://prod-ldap2.domain.com:636 bindmethod=simple binddn="cn=admin,dc=domain,dc=com" credentials=N… searchbase="cn=config" schemachecking=on type=refreshAndPersist retry="10 10 60 +" tls_reqcert=allow keepalive=240:10:30 olcSyncRepl: rid=001 provider=ldaps://prod-ldap1.domain.com:636 bindmethod=simple binddn="cn=admin,dc=domain,dc=com" credentials=N…… searchbase="cn=config" schemachecking=on type=refreshAndPersist retry="10 10 60 +" tls_reqcert=allow keepalive=240:10:30 - add: olcMirrorMode olcMirrorMode: TRUE Now once I do that I’ve experimented with changing the olcLogLevel and it seems to work. The rid’s on each node are different server2 has rid=002, server 1 has rid=001 as well as different olcServerID The part I run into issues is when I enable replication to the dc=domain,dc=com via dn: olcOverlay=syncprov,olcDatabase={2}mdb,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {2}syncprov olcSpCheckpoint: 20 10 olcSpSessionlog: 10000000 dn: olcDatabase={1}mdb,cn=config changetype: modify replace: olcSyncRepl olcSyncRepl: rid=021 provider=ldaps://prod-ldap1.domain.com:636 bindmethod=simple binddn="cn=admin,dc=domain,dc=com" credentials=N…. searchbase="dc=domain,dc=com" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on type=refreshAndPersist retry="5 10 60 +" tls_reqcert=allow keepalive=240:10:30 olcSyncRepl: rid=022 provider=ldaps://prod-ldap2.domain.com:636 bindmethod=simple binddn="cn=admin,dc=domain,dc=com" credentials=N…. searchbase="dc=domain,dc=com" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on type=refreshAndPersist retry="5 10 60 +" tls_reqcert=allow keepalive=240:10:30 - add: olcMirrorMode olcMirrorMode: TRUE I have 2 sets rids 001/002 and 021/022 and I have olcMirrorMode set to true on both cn=config and domain replication I’m pasting the relevant code around accesslog and syncprov that I think I’m getting wrong dn: olcOverlay={3}syncprov,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {3}syncprov olcSpNoPresent: TRUE olcSpReloadHint: TRUE structuralObjectClass: olcSyncProvConfig dn: olcOverlay={4}accesslog,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcAccessLogConfig olcOverlay: {4}accesslog olcAccessLogDB: cn=accesslog olcAccessLogOps: writes olcAccessLogPurge: 07+00:00 01+00:00 olcAccessLogSuccess: TRUE structuralObjectClass: olcAccessLogConfig dn: olcDatabase={2}mdb,cn=config objectClass: olcDatabaseConfig objectClass: olcMdbConfig olcDatabase: {2}mdb olcDbDirectory: /var/lib/ldap/accesslog olcSuffix: cn=accesslog olcRootDN: cn=admin,dc=adaptavist,dc=com olcDbIndex: default eq olcDbIndex: entryCSN,objectClass,reqEnd,reqResult,reqStart structuralObjectClass: olcMdbConfig dn: olcOverlay={0}syncprov,olcDatabase={2}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {0}syncprov olcSpNoPresent: TRUE olcSpReloadHint: TRUE structuralObjectClass: olcSyncProvConfig Replication works from node1 to node2, and in reverse. But it stops after 20 minutes or so After replication stops I see the on accesslog on one node has 4 records, on the other it has 3 and it never catches up even if I restart although at first it all works regardless of which node I update (change a random password) What am I doing wrong? Perhaps more than one thing Thank you
