How to make a temporary password expire?
by jeevan kc 13 Jul '13

13 Jul '13

With the Openldap password policy I was able to lock the account after a certain number of failed login attempts. When I reset the password, the user can login whenever. What I want to ask is, is there a way to make the password expire if the user doesn't login within lets say 24 hours after the password has been reset? Thank you! Jeevan

Is there a way reliable determine whether ldap slave is sync with master? Currently i am using ContextCSN diff between master and slave to determine the lag. Thanks in advance.

Do anyone point me right direction for setting up OTP authentication in openldap. Reference to URL or guide will be sufficient. -- Thanks & Regards Vishesh Kumar http://linuxmantra.com

Using distribution provided OpenLDAP builds is generally an extremely bad idea.

ldap syncrepl issue.
by Ashok 13 Jul '13

13 Jul '13

Hi, I am running ldap master and multiple slave with RefreshandPersist config. ldap search for an user shows different set of records. ContextCSN on master and slave are exactly same. What can i do to fix this. I tried restarting slave ldap but didn't help. Also i keep getting do_syncrepl: rid=112 rc 68 retrying every minute. I doubt if there is replication issue. Thanks, Ashok

olcSizeLimit become ignored somehow
by Покотиленко Костик 13 Jul '13

13 Jul '13

Hi, We have 1 master + 2 slaves setup (2.4.28, Ubuntu). We had an issue with only 500 search entries returned due to the default limit. I've added olcSizeLimit 100000 parameter to cn=config on all 3 servers and checked that all 3 servers return 500+ entries Ok. In a week or so the problem returned. I've checked - the setting existed on all 3 servers, but only one of them returned 500+, the rest 2 returned only 500 with 4 size limit exceeded. Solution was to change olcSizeLimit to some different value and then back. So, the question is how could slapd "forget" about the olcSizeLimit until it's changed? Known bug? Also, docs state that olcSizeLimit=0 is no limit, in fact it's literal 0. I've seen posts about that in the past, but it seems to still exist.

Q: Managing entryCSN with slapadd
by Ulrich Windl 12 Jul '13

12 Jul '13

Hi! I have a question: Is there a way to fix entryCSNs for slapadd? Reasoning: With dynamic configuration, sometimes (if you messed up) you'll have to edit your slapcat dump to reinitialize the config database. Unfortunately with replication the entry CSNs seem to casue trouble: If you don't change the CSN, the canges are not replicated, it seems; if you change the CSN, OpenLDAP doesn't seem to like it. I see repeating message slike these: slapd[3017]: Entry olcDatabase={0}config,cn=config CSN 20130709140112.108165Z#000000#000#000000 older or equal to ctx 20130709140112.108165Z#000000#000#000000 slapd[3017]: do_syncrep2: rid=001 CSN too old, ignoring 20130712085712.643156Z#000000#000#000000 (olcDatabase={2}monitor,cn=config) Ist there a way to fix this?

mdb grows to olcDbMaxsize if searched before syncrepl completes.
by Jancewicz, Russell 12 Jul '13

12 Jul '13

I am experiencing strange behavior when running an mdb database, as compared to the same system configured with hdb. If I conduct any queries while the server is receiving its initial data the server via syncrepl it stops receiving new entries and the data.mdb file balloons to the olcDbMaxsize value. I have tried adjusting configuration settings but regardless this continues to occur is this to be expected with mdb? It should be noted that if I wait for the entire database to replicate I can query the database fine and the size of data.mdb does not change. Furthermore if new changes are propagated down to the replica the issue does not arise. Any help would be appreciated. Please find below configuration ldifs and version information. -Russell J.

caseIgnoreMatch for Country String
by Maucci, Cyrille 11 Jul '13

11 Jul '13

Hello gurus, When I have this piece of schema included in my slapd.conf file... attributetype ( 1.3.6.1.4.1.11.11.1.1.1.1.402 NAME ( 'TestCountryString' 'TestCountryStringSyn' ) DESC 'Test Country String' EQUALITY caseIgnoreMatch ORDERING caseIgnoreOrderingMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.11 SINGLE-VALUE ) ... my 2.4.32 slapd -Tt complains with this error: line 8 attributetype: AttributeType inappropriate matching rule: "caseIgnoreMatch". My understanding of http://tools.ietf.org/html/rfc4517 is that caseIgnoreMatch is valid for country string: "The caseIgnoreMatch rule compares an assertion value of the Directory String syntax to an attribute value of a syntax (e.g., the Directory String, Printable String, Country String, or Telephone Number syntax) whose corresponding ASN.1 type is DirectoryString or one of its alternative string types. " Could you confirm whether this is a bug in openldap or simply a misunderstanding from me ? Thanks in advance ++Cyrille
