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.

Plans for the next LTS release?
by Sergio Durigan Junior 01 Feb '24

01 Feb '24

Hi there, Two years ago I sent an announcement mentioning that the OpenLDAP 2.5.x series was accepted for a Micro Release Exception in Ubuntu Jammy (20.04). This meant that I'd be able to release any updates to the 2.5.x series on Jammy, which I have been doing since then. We are now getting ready to work on the next Ubuntu LTS release, which will come out next April. I seem to remember upstream discussions mentioning that the next OpenLDAP LTS release would likely be the 2.7.x series, but I don't remember seeing anything else about it. Are there any plans to start working on the OpenLDAP LTS major series? Thanks a lot, -- Sergio GPG key ID: E92F D0B3 6B14 F1F4 D8E0 EB2F 106D A1C8 C3CB BF14

Scaling slapd nodes in Kubernetes with the MDB Backend
by Alejandro Imass 05 Jan '24

05 Jan '24

Hi there! We are working on a new installation and decided to try something new.. In the past I would have gone with multi-master with ldap balancer but after reading and researching more and more on MDB, we decided to try to integrate OpenLDAP into our current CI/CD pipelines using K8s. What we tried so far and it seems to work is initialize a common persistence storage and then an auto scaling group that shares that common drive. Ech pod has as many threads as virtual CPU it may have, and none of the pods can write, except a dedicated write pod (single instance) with multiple threads for writing. Is there anything else we are missing here? Any experience scaling OpenLDAP with Kubernetes or other container technology. Thank you in advance for any comments, pointers or recommendations! -- Alex

Most efficient way to update multivalued attributes
by Frédéric Goudal 20 Dec '23

20 Dec '23

Hello, I have to update records with mutlivalued attributes, and I wonder what is the best (fastest, or lighter for the server) to do : - either just set the value with the new list - or calculate which values to add and which to delete and than do the add and remove operations. And to be a bit more precise, if we have a big number of values is one of the two way best ? Thanks in advance f.g. — Frédéric Goudal Ingénieur Système, DSI Bordeaux-INP +33 556 84 23 11

Trying to get dynlist overlay to work
by Christoph Pleger 20 Dec '23

20 Dec '23

Hello, I am using OpenLDAP 2.5.13 from Debian and want to use the dynamic list overlay for replacing the memberOf overlay, but I cannot get it to work. As I read in several places, I first imported dyngroup.ldif, then created an ldif to load the dynlist module and the dynlist schema, like this: dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: dynlist dn: olcOverlay=dynlist,olcDatabase={1}mdb,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcDynamicList olcOverlay: {1}dynlist olcDlAttrSet: groupOfURLs memberURL member Then, I created a group with this ldif: dn: cn=Group1,ou=groups,dc=cs,dc=tu-dortmund,dc=de objectClass: groupOfURLs cn: Group1 memberURL: ldap:///dc=cs,dc=tu-dortmund,dc=de??sub?(employeeType=IT) But though some of the users have employeeType=IT, I cannot get a user attribute memberOf or alike that says that, for example ITuser1 is a member of Group1 . So, I tried another approach with dynlist that I read elsewhere: dn: olcOverlay=dynlist,olcDatabase={1}mdb,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcDynamicList olcOverlay: {1}dynlist olcDlAttrSet: groupOfURLs memberURL member+memberOf@groupOfNames But with this, I got an error message that memberOf@groupOfNames is unknown. So, I have some questions: 1. Does dynlist work this way only in OpenLDAP 2.6? 2. If no, do I have to import additional overlay ldifs? 3. Do I have to load additional modules other than dynlist? 4. Do I have to set other overlay attributes for the dynlist overlay? Regards Christoph

superuser and normal user in OpenLdap services

Hi, I am running the openldap server on Red Hat Enterprise Linux release 8.8 (Ootpa) # rpm -qa | grep -i ldap sssd-ldap-2.8.2-3.el8_8.x86_64 symas-openldap-servers-2.4.59-1.el8.x86_64 openldap-2.4.46-18.el8.x86_64 symas-openldap-2.4.59-1.el8.x86_64 symas-openldap-clients-2.4.59-1.el8.x86_64 # cat /etc/redhat-release Red Hat Enterprise Linux release 8.8 (Ootpa) # Do we have root and normal user privileges in OpenLDAP service as similar to Linux OS? For example, if I have to reset cn=admin password, do we need to use root or something? I am a little confused. Are there superuser concept in OpenLDAP? Please guide me. Thanks in advance. Best Regards, Kaushal

slapd 2.5 forwarding request .. please help
by enrico.becchetti＠gmail.com 09 Dec '23

09 Dec '23

Hi everyone, I have a particular setup and I need your help. I have a Slapd 2.5 running in a debian virtual machine. This ldap server has its own tree, dc=example,dc=com. I need this slapd server to forward the authentication requests for two domains other than its own, for example dc=example2,dc=com towards -> 192.168.1.1 dc=example3,dc=com towards -> 192.168.2.1 I read in the documentation that it is possible to do this forward but I can't modify the configuration using ldapmodify. Can you help me ? Thanks Willy
