olcPPolicyForwardUpdates not working
by Benjamin Renard 18 Jun '25

18 Jun '25

Hello, I have problem with the olcPPolicyForwardUpdates option that seem not working : On master and slave, I configured Ppolicy with pwdLockout. When I try to connect on master with a bad password, the pwdFailureTime attribute of the entry is successfully updated, but not if I do the same on the slave. On slave, my ppolicy configuration is exactly the same as on master but I add olcPPolicyForwardUpdates=TRUE. I also configured the chain overlay and the updateref parameter on the database. Extract of my slave configuration : olcDatabase={1}mdb,cn=config [...] olcSyncrepl: [...] olcUpdateRef: ldaps://ldap-master olcOverlay={0}chain,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcChainConfig objectClass: top olcOverlay: {0}chain olcChainReturnError: TRUE olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={1}mdb,cn=config objectClass: olcLDAPConfig objectClass: olcChainDatabase objectClass: top olcDatabase: {0}ldap olcDbURI: ldaps://ldap-master olcDbIDAssertBind: bindmethod=simple binddn="[same user used in olcSyncrepl of the database]" credentials="secret" mode=self olcDbRebindAsUser: TRUE olcOverlay={1}ppolicy,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcPPolicyConfig objectClass: top olcOverlay: {1}ppolicy olcPPolicyHashCleartext: TRUE olcPPolicyUseLockout: TRUE olcPPolicyForwardUpdates: TRUE Do you have any idea of what I doing wrong ?

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 16 Feb '24

16 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.)

Sorry!

What happened? Did I get hit by an oddball Syncrepl behavior? or Did I miss exchange. If this is bug,openldap 2.6.3 will be solved? Since both the main and slave systems were restored at the checkpoint, only the slave system remains in the log. Thanks for your time, Takashi

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?
