Hi I am very new to OpenLDAP, and we have a multi master configuration with us and our replication is not working. The error we get in log file is mainly : slap_client_connect: URI=<provider url> DN="cn=<sample value>,dc=<sample value>,dc=<sample value>" ldap_sasl_bind_s failed (-1). Attaching below logs after starting slapd service , Could you please help us ?

Thank you. > Just glancing at your script I see errors, such as: > > SASL_MECH GSSAPI PLAIN > > for ldap.conf. The man page clearly notes this takes a SINGLE mechanism. If ldap.conf(5) only supports one SASL mechanism for the SASL_MECH variable, then the man page at https://www.openldap.org/software/man.cgi?query=ldap.conf needs to be updated to clarify this. I originally configured the SASL_MECH variable for OpenLDAP's ldap.conf(5) the same way I configured the mech_list variable for Postfix's smtpd.conf and the auth_mechanisms variable for Dovecot's 10-auth.conf. I configured multiple SASL mechanisms for each of these variables for testing purposes. For a local area network, a system administrator has complete control over all the workstations and can make sure they all have Kerberos installed. For internet facing servers providing services to the wide area network (WAN), it makes sense to use a second SASL mechanism (something other than SASL/GSSAPI) in case any WAN devices do not have Kerberos installed, since a sysadmin may have no control over what is installed on WAN devices. I recently replaced libpam-ldap and libnss-ldap with sssd-ldap and sssd-krb5 for LinuxHA, since SSSD is a much better solution for identity and authentication. > Also, SASL/PLAIN is insecure and should never be used. Technically this is true. Even though when SASL/PLAIN is used in conjunction with Transport Layer Security, the credentials are encrypted. When ldap.conf(5) is installed on a server (as was the case when I was testing ldap.conf(5) on LinuxHA), using SASL/PLAIN is not insecure because it is only connected to a local socket on the local machine. > Another note is that SASL/GSASPI is extremely dependent on valid hostname > resolution. The pam ldap.conf seems unlikely to work (ldap://localhost for > the URI). When /etc/ldap.conf (the configuration file for PADL’s pam_ldap and nss_ldap modules) or /etc/ldap/ldap.conf (the configuration file for client applications such as ldapsearch, ldapadd, ldapmodify, and ldapdelete) is installed on a server rather than a workstation, you use "uri ldap://localhost", or "uri ldap://127.0.0.1", or better yet use LDAP over IPC mechanisms (LDAP over Inter-Process Communication) a.k.a. UNIX domain sockets (i.e., "uri ldapi:///"). See the following webpage for further details: https://datatracker.ietf.org/doc/html/draft-chu-ldap-ldapi-00 > I see so many things that are bad practice in this script in general I'm > not going to spend any more time reviewing it. I have tried very hard to make sure there are no “bad practices” incorporated into LinuxHA. From a security standpoint, I have attempted to design LinuxHA so it is one step ahead of standard security policies. Everytime Canonical releases a new version of Ubuntu Server, the configuration for LinuxHA has to be updated. I have tested LinuxHA on seven versions of Ubuntu Server thus far — from 12.04 to 24.04. Even though I try to go through all the software packages incorporated into LinuxHA everytime Canonical releases a new version of Ubuntu Server to see if any configuration file has changed and needs to be updated, it may take awhile to complete these updates. If you find any misconfiguration in LinuxHA, please submit a bug report: https://bugs.launchpad.net/linuxha/+filebug Kind regards, Travis Bean

list members, i have a multi-provider footprint that i want to remove the AutoCA functionality from. when i loaded the overlay, i set it to disabled, per the below: dn: olcOverlay={5}autoca objectClass: olcOverlayConfig objectClass: olcAutoCAConfig objectClass: top olcOverlay: {5}autoca structuralObjectClass: olcAutoCAConfig entryUUID: 739501f2-49ad-103e-911a-3dc9b40470bf creatorsName: uid=brendan,ou=domainusers,ou=users,dc=bpk2,dc=com createTimestamp: 20240117175614Z olcAutoCADays: 3650 olcAutoCAKeybits: 2048 olcDisabled: TRUE olcAutoCAserverKeybits: 2048 olcAutoCAuserClass: inetOrgPerson olcAutoCAserverClass: device olcAutoCAserverDays: 1826 olcAutoCAuserDays: 365 olcAutoCAuserKeybits: 2048 entryCSN: 20240117192443.210024Z#000000#001#000000 modifiersName: uid=brendan,ou=domainusers,ou=users,dc=bpk2,dc=com modifyTimestamp: 20240117192443Z note, olcDisabled is set to true. it seems that something went awry and even though i didn't want the capability active, i wound up with some caCertificate and caPrivateKey objects created in the DIT. it looks like i may have added the overlay in an active state and disabled it after the caCertificate/PrivateKey objects were created. i want to clean up things and remove the AutoCA pieces until i can test them better. what process is needed to remove the objects and overlay, as replication may play a part in some of the effort? i could imagine that deleting the caCertificate and caPrivateKey objects would be relatively straight forward, but the overlay may prove a bit more complicated. i found a message on this list from some time ago, https://www.openldap.com/lists/openldap-technical/201811/msg00075.html, that says i can stop the slapd instance, remove the overlay ldif files and restart the instance, to accomplish this task. the issue that i am trying to avoid is having to take down the entire fully replicated DIT, in order to delete the overlay and not have replication recreate it because one active node "didn't get the memo". are there any insights into how i can delete overlays without having replication recreate the objects i want to remove, all while still providing at least one instance to service requests? if it clarifies things, i am running 3 slapd instances behind a load balancer and both the config DB and DIT are replicated between all nodes. if it comes to it, i could take down all instances to perform this work, but i would like to avoid it if possible. thanks in advance, brendan kearney

Unnamed sub-databases in LMDB
by ruben.soh＠rutgers.edu 26 Oct '24

26 Oct '24

Background: I am trying to implement a fully dynamic connectivity algorithm, based on this paper (https://dl.acm.org/doi/10.1145/502090.502095), using LMDB as the backend. Other implementations use an in-memory binary search tree. I am currently working on trying to implement an Euler Tour Forest using LMDB. Essentially, an Euler Tour of an unbalanced tree is obtained by doing a DFS and assigning an increasing index every time we visit a node (https://en.m.wikipedia.org/wiki/Euler_tour_technique). An Euler Tour Tree is simply a balanced tree containing the euler tour index as the key and a pointer to the node as the value, so I plan to store each Euler Tour Tree using an LMDB database. Problem: I need an unlimited amount of sub-databases - my first thought was to use mdb_dbi_open, however, it seems like this doesn't scale well because a list of named sub-databases is stored in every transaction. In the talk about LMDB's functionality at CMU (https://www.youtube.com/watch?v=tEa5sAh-kVk) there is some reference to sub-databases, but from reading the code it seems like unnamed sub-databases are only used for sorted duplicate keys. Am I correct in thinking that I'm going to need to add some new code to support unnamed sub-databases, or is there some way to do it that I'm not recognizing? And if I do need to change things, where should I start? Ruben Soh

Error after OpenLDAP update from 2.4 to 2.5 - ppolicy schema
by sharbich＠t-online.de 21 Oct '24

21 Oct '24

Hello, unfortunately I missed the update version note for the schema ppolicy. After updating and restarting the slapd service, I can no longer delete the schema. I get the following error message: "root@dsme01:~# slapcat -n0 > config.ldif olcAttributeTypes: value #0 olcAttributeTypes: Duplicate attributeType: "1.3.6.1.4.1.42.2.27.8.1.1" config error processing cn={15}ppolicy,cn=schema,cn=config: olcAttributeTypes: Duplicate attributeType: "1.3.6.1.4.1.42.2.27.8.1.1" slapcat: bad configuration file!" What can I do now? Greetings from Stefan Harbich

Help me understand LMDB internals
by ruben.soh＠rutgers.edu 20 Oct '24

20 Oct '24

I am a student trying to understand the code for LMDB. One thing I am confused about - there is apparently no mutex for creating a reader transaction. In the function mdb_txn_renew0, which is called by mdb_txn_begin to create the transaction, I see that if we are creating a read-only transaction, we select a meta page without acquiring any mutex. Then, the meta page snapshotted in these lines (and accessed later in the function as well): /* Copy the DB info and flags */ memcpy(txn->mt_dbs, meta->mm_dbs, CORE_DBS * sizeof(MDB_db)); /* Moved to here to avoid a data race in read TXNs */ txn->mt_next_pgno = meta->mm_last_pg+1; What happens if a write transaction commits to the meta page while this copy is happening? Isn't it possible that the reader transaction will have copied an inconsistent view of the meta page? Sincerely, Ruben

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.

Advice for upgrade from OpenLDAP 2.4 to 2.6?
by gsafcik+ldap＠gmail.com 15 Oct '24

15 Oct '24

Hello all, We are planning an upgrade from OpenLDAP 2.4 to 2.6. We would like some guidance on the upgrade path. We are currently looking over the upgrade guides: - https://www.openldap.org/doc/admin25/appendix-upgrading.html - https://www.openldap.org/doc/admin26/appendix-upgrading.html Currently, we build OpenLDAP from source to create the RPMs and then install them. We are building version 2.4.56-4. Originally they were built for CentOS 7, but we've recently converted to AWS AL2023. We have 3 mdb write instances (synced to each other) and then many hdb read instances (consumers) syncing to those. The following are the RPMs built: - openldap-2.4.56-4.el7.x86_64.rpm - openldap-clients-2.4.56-4.el7.x86_64.rpm - openldap-compat-2.4.56-4.el7.x86_64.rpm - openldap-debuginfo-2.4.56-4.el7.x86_64.rpm - openldap-devel-2.4.56-4.el7.x86_64.rpm - openldap-servers-2.4.56-4.el7.x86_64.rpm We plan on addressing the components listed in those guides earlier and to build/install version 2.6 as we have before. We have run into an issue before where CPU spiked on our consumers when we tried to change them to mdb which stopped the 2.5 upgrade but now we're thinking of upgrading and changing the backend to mdb at the same time for the upgrade. We wanted to see if anyone has any advice or caveats that they've run into during their upgrades and to see if this general upgrade path is good. We appreciate any help anyone can offer with the OpenLDAP upgrade. Thanks!

ACL: write vs. manage
by Windl, Ulrich 14 Oct '24

14 Oct '24

Hi! Basically I have the same question as unanswered https://serverfault.com/q/998893/407952: What is the difference between write and manage? I have a use with write permissions for pwdGraceUseTime, and deleting that attribute requires "-e relax" for ldapmodify. However when my user ties it, it gets a ldap_modify: Insufficient access (50) Kind regards, Ulrich

symas2.6.7 is data transfer is faster in centos7 but very very slow in rocky8
by anilkumar.pathuri7＠gmail.com 11 Oct '24

11 Oct '24

Hi Team, GM We are working on moving from openldap2.4.44 to symasldap2.6.7. We have total of 13million docs. centos7 to centos7 is taking 1~2hours where as rocky8 is taking 48hours and more. Settings of centos7 and rocky8 are identical. We are moving to rocky8 as centos7 is EOL. Can you please let us know how we can fix the data transfer issue. Regards, Anil P
