Replicate cn=config between masters and slaves?

by Karsten Heymann

Hi, when setting up a cluster with 1+x masters and 1+x slaves, is it possible to use a single cn=config replicated between all of these? Or do masters and slaves need to have different settings anyhow. I'd like not to have to manage schema information and acls in two places. Best, Karsten

search on multimaster gives 2 different results

by Gare Calhoun

Hello, We are running 2 servers in multimaster mode ; openldap-2.4.35 on CentOS 6.6 using the autogroup overlay. I have a search filter (APersonCategory=*ADJ*) that returns different numbers of records when queried against each server. The actual records exist on both servers. 1 server is not returning all expected records. The other server returns records as expected. There is no index defined for this attribute in slapd.conf on either server. schema definition of attribute is same on each server: attributetype ( 1.3.6.1.4.1.5923.1.1.1.23 NAME 'APersonCategory' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) Would someone suggest what to look at to troubleshoot this? Thank you very much for your assistance. -Gare Calhoun -- . . . . . . . . . . . . . . . . . . . . . . . . . . . . Gare Calhoun Antioch University IT Services, Software Developer

Fw: TLS Configurations with OpenLDAP-2.4.23 on CentOS-6.2 --- Low Sensitivity/Aerospace Internal Use Only

by Warron S French

Low Sensitivity/Aerospace Internal Use Only Quanah, I downloaded the RPMs for OpenLDAP-LTB, but I didn't see anything that looked like my prior OpenLDAP (original) files. With my prior set, I was doing configuration changes in the /etc/openldap/slapd.d/cn=config directory's files. I didn't feel comfortable with moving forward because I found no README file or Getting Started or whatever. I was also looking for such documentation on the www.ltb-project.org website so that I could get a preliminary idea of what I was going to do, before I executed the installation and configuration steps. One of my major concerns is the ability to update the binaries on a regular basis for security purposes. I need to do it very easily and without re-engineering a yum repository every time there is an update. I am going to be building this LDAP system on a totally isolated environment, NO internet access at all. Can you (or anyone else) tell me, do I need to register with the LTB-Project.org website in order to find good, solid, installation and configuration instructions for what I need to accomplish? I am a newbie at OpenLDAP, I am senior in UNIX skills. I just have never had a single successful implementation of OpenLDAP.

Monitoring back-mdb's olcDbMaxSize

by Michael Ströder

HI! Using back-mdb there's one thing which could cause trouble: One has to configure olcDbMaxSize which cannot be changed later. So when monitoring OpenLDAP with back-mdb it would be interesting to see how much space of configured olcDbMaxSize is already occupied. Does it make sense to compare the real file size shown by du -h /path/to/data.mdb to configured olcDbMaxSize? Ciao, Michael.

TLS: peer cert untrusted or revoked (0x42)

by Kumar, Amit

Dear All, We have installed a newer version of Ubuntu 13.10 and trying to setup LDAP client. Context: Self signed server CA certificate in pem format installed on the client with a hashed symbolic link pointing to it. We have other clients that are able to validate and are working great, hence I do not think this is a certificate issue, and also it is not expired. And I get this legendary error "TLS: peer cert untrusted or revoked (0x42)" for which number of recommendation have been made online, to set TLS_REQCERT & TLS_CACERT in the /etc/ldap.conf Although this did not work for me. While openssl and gnutls command can successfully connect and validate the certificate, ldapsearch and getent miserably fails. Any insight into this error and an approach to fix this will be greatly appreciated. Best Regards, Amit
