ldif_back_add: err: 68 text:

Hi! Trying to start test server (openldap 2.4.25) on my home box (FreeBSD 8.2 i386) I get this error: ... ldif_back_add: "olcDatabase={0}config,cn=config" oc_check_required entry (olcDatabase={0}config,cn=config), objectClass "olcDatabaseConfig" oc_check_allowed type "objectClass" oc_check_allowed type "olcDatabase" oc_check_allowed type "olcAddContentAcl" oc_check_allowed type "olcLastMod" oc_check_allowed type "olcMaxDerefDepth" oc_check_allowed type "olcReadOnly" oc_check_allowed type "olcRootDN" oc_check_allowed type "olcSyncUseSubentry" oc_check_allowed type "olcMonitoring" oc_check_allowed type "structuralObjectClass" oc_check_allowed type "entryUUID" oc_check_allowed type "creatorsName" oc_check_allowed type "createTimestamp" oc_check_allowed type "entryCSN" oc_check_allowed type "modifiersName" oc_check_allowed type "modifyTimestamp" ldif_back_add: err: 68 text: send_ldap_result: conn=-1 op=0 p=0 send_ldap_result: err=68 matched="" text="" slapd destroy: freeing system resources. slapd stopped. connections_destroy: nothing to destroy.

I googled that error 68 means that there is duplicate entry in the DIT but there is no text part in the message so I don't know what entry is causing the error. Any help would be greatly appreciated!

OpenLDAP 2.4.28 RPMs for CentOS 5 and CentOS 6
by Clément OUDOT 06 Jan '12

06 Jan '12

Hi, I just published new versions of OpenLDAP 2.4.28 RPMs, for CentOS 5 and CentOS 6, see http://ltb-project.org/wiki/download#openldap They include a new version of init script in which I added two commands: # service slapd backupconfig # service slapd restoreconfig This allows to dump your cn=config, edit it and reload it very quick. Hope it helps, Clément.

misconfigured read-only replica causes master slapd to crash
by Kevan Carstensen 05 Jan '12

05 Jan '12

Hi, We use a single master and two read-only replicas; we use back-bdb on all systems. Each read-only replica replicates from the master with syncrepl, configured to refreshAndPersist. During a particularly heavy update load recently, replication on one of the read-only replicas started to fail due to a misconfigured DB_CONFIG. The replica wrote the following messages to its log repeatedly: Dec 14 04:01:08 pip-dev slapd[12645]: bdb(dc=csupomona,dc=edu): Lock table is out of available lock entries Dec 14 04:01:08 pip-dev slapd[12645]: => bdb_idl_delete_key: c_get failed: Cannot allocate memory (12) Dec 14 04:01:08 pip-dev slapd[12645]: conn=-1 op=0: attribute "memberUid" index delete failure Dec 14 04:01:08 pip-dev slapd[12645]: null_callback : error code 0x50 Dec 14 04:01:08 pip-dev slapd[12645]: syncrepl_entry: rid=001 be_modify failed (80) Dec 14 04:01:08 pip-dev slapd[12645]: do_syncrepl: rid=001 rc 80 retrying as it tried and failed to start replication again. Shortly after, the master slapd crashed, writing nothing to its log indicating why (or even referencing the crash at all). We initially noticed this behavior with a 2.4.26 master and a 2.4.28 read-only replica (we came upon this problem while performing some maintenance, which is why there's a version mismatch). I reproduced the problem on a 2.4.28 master while researching ITS #7113 [1] (which describes this problem more precisely and in more detail). Has anyone else run into this issue? Is there a good way to insulate the master slapd from misconfigured replicas? Our replicas shouldn't break like this (we've tuned our DB_CONFIG to ensure that they don't in the future), and hopefully slapd can be modified so that the master doesn't crash even if replicas do break, but we'd rather not have to worry about our master crashing if our DB_CONFIG proves inadequate in the meantime.

Re: Issue with index in OpenLDAP?
by External Mathieu DEDECKER (CAMPUS) 05 Jan '12

Hi Quanah and thank you again for your quick reply, I did not deleted the *.bdb files, but I moved them in a backup folder. My /db folder was empty, but the slapindex command failed because both "dn2id.bdb" and "id2entry.bdb" files was not present. I needed to add them in the /db folder in order to run the slapindex command. Then, all index have been re-generated. After the reindexation, the "cardnumber.bdb" file had the same size than before. Could you confirm me that it's the best process to reindex an OpenLDAP?

problem with authentication to AD server with translucent overlay
by juhlig 04 Jan '12

04 Jan '12

I am using openldap 2.4.23-20 on Centos 6.2 server and trying to configure the translucent overlay to do simple user/password authentication (or anything that works) to our Microsoft AD servers. I can do authenticated commandline ldap searches with a Windows test account and password with no problems. I have tried to build a config based on the examples in the openldap admin and faq-o-matic web pages without success. All I get from the AD servers through my server are anonymous bind results. If anyone has this working, I would appreciate any information or config file samples as I need to deploy the server ASAP. thanks, John. p.s. I am not including my config files (ldap.conf,slapd.conf,etc.) as they are essentially copies of the ones from the openldap website. However, if you wish to see them, I can reply with the latest of 100 iterations :(

I will read the man page in order to have more informations about the command. I tried to reindex all the index of the database with the slapindex command, but I allways the same behaviour: Request1: cardnumber=2098001010034 (less than 1sec) Request2: cardnumber=2090389917486 (nearly 20 sec). Other .bdb files size have been updated, but my "cardnumber.bdb" has still the same size.

No. I read that since OpenLDAP 2.3 this was not necessary (I'm running 2.4.25 on Ubuntu 11.10). I got my project from a tutorial [1] where this all worked.

Hi Mathieu, If you read the slapindex man page, it is possibly to just recreate a specific index file (for situations like this), rather than generating all of them. --Quanah --On Wednesday, January 04, 2012 10:39 AM +0100 "External Mathieu DEDECKER (CAMPUS)" <external.z02mdebe(a)oxylane.com> wrote: > Hello Quanah, > > First I would like to thank you for your answer. > > Indeed, I also think that the "cardnumber" index is somehow corrupted. > His size is to small in comparison to other indexes > > We suppressed all existing index and Used slapindex to re-create them all. > > It's undergoing. > > I will keep you informed about the solution. > > Best Regards, > > Mathieu > > > 2012/1/3 Quanah Gibson-Mount <quanah(a)zimbra.com> > > > --On Friday, December 23, 2011 11:27 AM +0100 "External Mathieu DEDECKER > (CAMPUS)" <external.z02mdebe(a)oxylane.com> wrote: > > > Hi @All, > > We meet a performance problem with our OpenLDAP. > > We think that we face a problem with the index of the database, and we > think that the problem can be resolve by tunning the config (but not > sure). > > We would like to be sure that our configuration is correct, in order to > confirm if we are on a wrong track or not. > > [Description] > > We have an attribute (cardNumber) which is indexed. > > When we request the indexed attribute (cardNumber) with an LDAP Client > (Ldapbrowser), we have either fast or very long response time. > > For the long response time, the CPU of the server hits 100%. > > For example: > > Request1: cardnumber=2098001010034 (less than 1sec) > Request2: cardnumber=2090389917486 (nearly 20 sec). > > By checking the hit ratio of the attribute, we can see that cache is > correctly used (97%). > > > It sounds like you added an index to cardnumber after there was already > data for cardnumber in your database, and didn't run slapindex for that > attribute.

Hello Quanah, First I would like to thank you for your answer. Indeed, I also think that the "cardnumber" index is somehow corrupted. His size is to small in comparison to other indexes We suppressed all existing index and Used slapindex to re-create them all. It's undergoing. I will keep you informed about the solution.
