Tutorials: 11th November 2015 Conference: 12th and 13th November 2015 Call for papers and tutorials ============================= Topics You are using LDAP in interesting projects? You do LDAP client or server development? You have used LDAP in a new way? You do identity and access management on top of LDAP? Why not share your ideas and experiences with others? We are looking for speakers who are willing to talk about any topic related to LDAP and identity management, including: LDAP technology implementation (Servers, API, User interfaces etc.) LDAP Usage (Schema, Security, Operations, Scaling, big data, etc.) LDAP related technologies (PKI, XACML, SAML, etc.) LDAP and Beyond (IAM, Identity Federation, Authentication on the web, etc.) Best Practices for directory services. Accepted talks will be grouped into tracks such as a standards/development and deployment/administration. Deadlines & Important Dates Submission Deadline: 28th June Author Notification: 10th July Final Papers due: 10th October 2015 Tutorials: 11th November 2015 Conference: 12th-13th November 2015 Talk Submissions Main presentations should last about 45 minutes including discussion; we will also provide smaller slots of 15 minutes and 5 minutes for poster presentations or lightning talks. Please tell us which duration you prefer when proposing your talk. The talk must be in English. The one and only way to submit your abstract (approximately 200-800 words, accompanied by your biography of about 100-300 words) is via email to submissions(a)lists.ldapcon.org. Abstracts must reach the Program Committee by 28th June 2015. Early submission is encouraged. All abstracts will be reviewed by the program committee. For accepted talks we expect you to submit slides and/or a paper of approximately 2-10 pages (A4 or US Letter format, 25mm borders, preferably LaTeX source or OpenOffice). For 5-minute talks, a brief abstract is required. A short paper, slides or a poster should be provided for accepted talks. We will provide display boards for posters throughout the conference. By submitting a paper you grant the conference organizers the non-exclusive right to publish your paper in the conference proceedings and on the website; you maintain the right to publish it elsewhere at your discretion. Tutorial Submissions We are looking for high-quality tutorials on LDAP and related subjects, at any level from introductory to advanced. Tutorial length can range from an hour to a full day. Wireless Internet access will be available if required. The purpose of the tutorials is focussed education, so they should cover established topics and best practice rather than presenting new work. Tutorials will be on Wednesday 11th November 2015. The Programme Committee has an open mind about the format of the tutorial day, but has a limited number of rooms available. Make your proposal early and we will aim to build an attractive programme for the day. Expenses Speakers get free access to the conference, including the social event. If requested in advance we will provide accommodation for speakers. Travel expenses might also be covered in special cases. If you need this, please contact us early so we can try to arrange it.

Search with wildcard
by Alessandro Lasmar Mourao 28 Jan '15

28 Jan '15

I have the following structure in my OpenLDAP: ou = groups |_cn = system1 | | _cn = Group1 | | _cn = Group2 |_cn = system2 | _cn = Group1 | _cn = Group2 I need to perform a search and return only users who are registered on system1, regardless of the registered group. When I use the search with the filter: memberOf=cn=*,cn=system1,ou=groups nothing is returned. How do I perform this search in OpenLDAP? In search Oracle SJDS works!

OpenLDAP Replication Issue
by Tony S. Wu 26 Jan '15

26 Jan '15

We have 5 servers running OpenLDAP, 001 - 005. Server is CentOS 6.4, LDAP version is openldap-servers-2.4.23-32.el6_4.1.x86_64, current replication topology is: 001 <=> 002 001 <=> 003 001 <=> 004 001 <=> 005 001 is where the phpLDAPAdmin GUI is running on. 002 - 005 are behind a load balancer, 001 is never directly accessed from clients. I understand this makes 001 the single point of failure in terms of replication, but we would like to fix the current issues before exploring more changes. The issue we are running is intermittent failure in replication. Replication is configured as multi-way master with mirror mode, it always works from 001 to the rest, but sometimes fails the other direction. This is particularly bad when user changes password and it doesn't get replicated to back to 001, and when that happens it doesn't get replicated to the rest of the other servers. In the log we see the following error messages sometimes, but when replication fails sometimes there is no log: Error Log: Jan 21 10:56:42 001 slapd[27161]: do_syncrepl: rid=004 rc -2 retrying (4 retries left) Another issue is failure on slapd service. On each of the server we have a cronjob running that basically dumps the database using slapcat once an hour. However once every 2 weeks or so we would find slapd dead right around the same time slapcat was run. There is no obvious error in ldap log, system log, or dmesg. According to the documentation it is safe to run slapcat while slapd is running, is this not true? Below is the replication section of the configuration on 001 and 004. If someone could advise on this it would be very much appreciated. moduleload syncprov.la serverid 1 cachesize 50000 idlcachesize 50000 syncrepl rid=002 provider=ldap://002.server.com binddn="uid=replication,ou=Services,dc=server,dc=com" bindmethod=simple credentials=******** searchbase="dc=server,dc=com" type=refreshAndPersist interval=00:00:00:10 retry="5 5 300 5" timeout=1 starttls=yes tls_reqcert=never * repeat for 003, 004, and 005 * mirrormode true overlay syncprov syncprov-checkpoint 1000 60 syncprov-sessionlog 100 index entryCSN,entryUUID eq

Or make 001 and 002 a MMR cluster, which work as provider for your 003 to 005 as read-only replicas, which sent referrals to the provider cluster or use chaining. (You may use a service address for the cluster and move phpLDAPAdmin GUI to the cluster as well.) Maybe these are more commonly used setups than your current one. Marc

LDAP ldapsearch filter: return uidNumber if person has sub ou=mail
by Leander Schäfer 25 Jan '15

25 Jan '15

I'm trying to construct a ldap filter for my Dovecot/Postfix setup which acts as the example pseudo code & result below: |return uidNumber OF objectClass=posixAccount IF they have a ou=mail AND the mailAddress in this ou=mail IS EQUAL to test(a)Mydomain.TLD || # User-1, people, Mydomain.TLD dn: uid=||User-1,ou=people,dc=MyDomain,dc=TLD uidNumber: 2110 | More specific like this while %s holds e.g.: test(a)Mydomain.TLD: |search_base = dc=Mydomain,dc=TLD query_filter = ( &(objectClass=posixAccount)(ou=mail)(mailAddress=%s) ) result_attribute = uidNumber | But obviously uidNumber is being hold by the posixAccount container one level above - and therewith it won't display what I want. Unfortunately I couldn't figure out how to get it work. My LDAP structure looks like this: => dc=MyDomain,dc=TLD ==> ou=People ===> uid=User-1 ====> uidNumber=4035 ====> ou=mail =====> mailAddress=test(a)Mydomain.TLD ===> uid=User-2 Any help would be greatly apprecitated Thanks Best Regards Leander

occasional user entry being deleted
by Al 22 Jan '15

22 Jan '15

Hi All - I'm having an odd issue where on a rare occasion (a couple of times a week), a new LDAP user entry is being deleted shortly after it is created. Sometimes it happens within a few minutes, sometimes it happens within an hour or so. I have a 4 way multi-master setup, with all writes being directed at a single server with a load balancer. I have the auditlog enabled (from failed attempts at delta sync) and I see auditDelete entries in the auditdb, but its being executed from the internal admin user, not a "real" user. I do not see anything suspect in my system logs running at the normal loglevel. I'm running 2.4.39 on Redhat 6, x64 with mdb. Below is a snippet of my configuration from the specific database in question. Does anyone know why this might be occurring? Any idea on how to further troubleshoot this issue?
