Upgrading from Ubuntu-packaged 2.4.28 to self-built 2.4.38
by Philip Colmer 12 Dec '13

12 Dec '13

Our current implementation of OpenLDAP is Ubuntu 12.04 running version 2.4.28 which has been installed as a package. To upgrade to 2.4.38, it looks like I need to remove that package and then install my own built binaries. Has anyone gone through this process before and got any tips/notes to share? I'm particularly thinking that there will be some path changes to contend with. For example, my main HDB database seems to be in /var/lib/ldap but the migration steps suggest that everything is in /usr/local/var/openldap-data/. Clearly I can work through this but if someone has already done it and can share lessons learnt, that would be much appreciated. Philip

Running slapcat and slapd at the same time
by Chris Card 12 Dec '13

12 Dec '13

Hi all, I am running openldap 2.4.36 with Berkeley DB 4.6.21 under centos 6.3 64 bit on a Dell 710 with 96 Gb RAM. My slapd configuration sets the BDB cachesize to use a shared memory segment of 47 Gb (id2entry.bdb is about 40 Gb currently). I use slapcat to take regular backups using the same configuration as slapd, running in parallel with slapd, and the backup works successfully, but uses a lot of memory when it is running. I would like to be able to run slapcat with a smaller memory requirement, and to this end I have experimented with running slapcat with a different configuration as follows: 1. create a work directory 2. create links in the work directory to the .bdb files 3. slapcat cn=config to an ldif file 4. edit the ldif file to change the db data directory to the work directory and change the olcDbConfig settings to use less memory 5. slapadd the ldif file to create a new slapd.d config directory in the work directory 6. run slapcat with the new slapd.d config The reason for this approach is to allow slapcat to run with a different DB_CONFIG file to slapd. This appeared to work in testing, but in the production environment produced backups with data missing, while outputting no error messages. Is there a way to run slapcat with a different memory configuration to slapd? Chris

please fix ITS#6825
by Michael Ströder 12 Dec '13

12 Dec '13

HI! I have a setup where I cannot work around ITS#6825 by putting posixGroup entries in a single container. So I hit this bug again where slapo-unique does not behave as documented: http://www.openldap.org/its/index.cgi?findid=6825 Is there a chance to get this fixed soon? Ciao, Michael.

2 way SSL configuration in OpenLDAP 2.4
by vidya bharadwaj 11 Dec '13

11 Dec '13

Hi, We have to implement a 2 way SSL mechanism on a LDAP connector in our product. In order to test the implementation, we have chosen openLDAP2.4 as the data source. Currently we have done the following steps: On the OpenLDAP end: 1. Installed OpenLDAP with TLS feature 2.Created a CA using OpenSSL /etc/pki/tls/misc/CA –newca 3.Created a certificate using OpenSSL openssl req -newkey rsa:1024 -nodes -keyout newreq.pem -out newreq.pem 4.Signed the certificate using the CA created /etc/pki/tls/misc/CA –sign 5. Finally stored the cacert.pem, newreq.pem and newcert.pem under /opt/openldap/certificate folder 6. Following changes were made in sldap.conf TLSCipherSuite MEDIUM:+SSLv2:+SSLv3:RSA TLSCACertificatePath /opt/openldap/certificate/ TLSCACertificateFile /opt/openldap/certificate/cacert.pem TLSCertificateFile /opt/openldap/certificate/servercrt.pem TLSCertificateKeyFile /opt/openldap/certificate/serverkey.pem # Use the following if client authentication is required TLSVerifyClient demand 7.Similarly a new certificate for client was created using client’s details such as host name etc 8.Signed by the previously created CA On the client side: 1. Following changes were made in ldap.conf HOST spsdel192 PORT 636 TLS_CACERTDIR/etc/openldap/certs TLS_REQCERT demand TLS_CACERT /etc/openldap/certs/cacert.pem Finally when executing [root@spsdel193 ~]# ldapsearch -v -Z -D cn=root,o=ShawEnterprise -w secret -b o=accounts,o=shawEnterprise ldap_initialize( <DEFAULT> ) ldap_start_tls: Connect error (-11) additional info: TLS error -12227:SSL peer was unable to negotiate an acceptable set of security parameters. ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) [root@spsdel193 ~]# Any solution to resolve this issue would be of great help. Thanks in advance. Regards Vidya

Here's what I read out of your answer: (ldap2) slapcat -bcn=config -l config.ldiff (ldap2) slapcat -l actual-data.ldiff (ldap1) rm -rf /var/lib/ldap/* (ldap1) /etc/init.d/slapd start (ldap1) slapadd -bcn=config -l config.ldiff (ldap1) slapcat -l actual-data.ldiff Like this?

Servers ignore their own changes. > You're saying I shouldn't delete the files before doing the cat/add business, right? If I'd do it like this, wouldn't stuff that got deleted on ldap2 (while ldap1 was down) still end up being on ldap1?

Custom attribute values created prior to an index are not getting indexed by slapindex
by Jon C Kidder 11 Dec '13

11 Dec '13

I am running 2.4.36 with mdb and have discovered an interesting behavior that may be a bug but wanted some input before I opened an ITS. I can upgrade to .38 and verify the behavior if needed. I have a third party application that defines the following custom attribute: olcAttributeTypes: ( 1.3.6.1.4.1.8241.1.15 NAME 'ctscPropertyKeywords' EQUALITY caseIgnoreMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) I have recently added the following index to the database for this application: olcDbIndex: ctscPropertyKeywords pres,eq When I run a search using objectclass as a filter I see 17 records that contain the value "Exportable" for ctscPropertyKeywords. When I repeat the search using (ctscPropertyKeywords=Exportable) as the filter I only get back 9 records even though the value is present in 17 records. I have included examples of my searches and the results below. I have run slapindex on this database several times since the new index was added using: /appl/openldap/sbin/slapindex -v -F /appl/openldap/etc/openldap/slapd.d -b "dc=global,dc=aep,dc=com" I have also restarted slapd several times just for grins. The behavior has not changed. I have discovered that the 9 records I see have been modified since the index was created and the missing 8 records existed before the index was created. Modifying a record causes the index to get updated and adds the record to the results of my second search but re-indexing the database using slapindex does not. Any thoughts? Here are my sample searches and their output. /appl/openldap/bin/ldapsearch -H "ldap://localhost:389" -x -D {removed} -y {removed} -s sub -b 'dc=Global,dc=aep,dc=com' '(objectClass=ctscPropertyDefinition)' objectClass ctscPropertyKeywords #

Replicating cn=config in configuration tool
by Daniel J 10 Dec '13

10 Dec '13

Hi Openldap gents/ladies, For those who migrated over to cn=config and are replicating cn=config as well as other DIT using configuration tools like cfengine, puppet, chef etc... I have currently have set up to not replicate cn=config for the following reasons: - flexibility to run different cn=config if needed for testing/for a specific purpose - able to reduce the scope of changes that may be disastrous Curious to know how others have implemented and theirs reasoning behind his/hers implementation. Your comments and advise are very welcome. Thanks

Recovering from a Single-Node downtime in a Multi-Master Setup
by Marco Nett 10 Dec '13

10 Dec '13

Quick question: State 1: - I have two OpenLDAP slapd servers (ldap1 and ldap2) configured as Multi-master. - The both have the exact same data between the mirrored directories. - If I create a new directory entry on one server, it immediately gets mirrored to the second server. - I'm happy. State 2: - One LDAP-Master (ldap1) is down because of whatever. - Changes to the directory are made on the LDAP-Master which is still up (ldap2). - Changes are not mirrored to ldap1 because it's down. - I'm a little worried but still happy. State 3: - ldap1 is back up and running, but it's directory is not up to date. - The changes made to ldap2 in state 2 are not on ldap1 and aren't getting replicated automatically. - Mirroring again works fine, but ldap1 still doens't know about changes made in state 2. - I'm confused because I can't seem to find any information on how to recover from this. I couldn't just delete the directory on ldap1 and import the one from ldap2 because the importing would also be mirrored to ldap2. right? how would i go about recoverying from a downtime in a multi-master setup?
