dnMatch flooding logs and access blocked
by Al Dispennette 05 Dec '12

05 Dec '12

Hello, I am seeing the following get repeated in my slapd logs for hundreds of line. I know it is due to the logging level. However, when this starts happening no one can access the server because what ever is logging this is blocking. Can anyone tell me what is causing this log entry? slapd[20616]: dnMatch -1#012#011"uid=item1,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" slapd[20616]: dnMatch 2#012#011"uid=item2,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" slapd[20616]: dnMatch 2#012#011"uid=item3,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" slapd[20616]: dnMatch -2#012#011"uid=item4,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" slapd[20616]: dnMatch -1#012#011"uid=item5,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" slapd[20616]: dnMatch -2#012#011"uid=item6,ou=users,dc=example,dc=com"#012#011"uid=user,ou=users,dc=example,dc=com" Al Dispennette Sr. Software Engineer t: 415 526 7206 m: 309 868 1401 al.dispennette(a)monitise.com<mailto:al.dispennette@monitise.com> [Description: Description: Description: http://mailmedia.monitisegroup.com/MonitiseUpdate/Images/Email_logo.gif] www.monitisegroup.com<http://www.monitisegroup.com/> [Description: Description: Description: http://mailmedia.monitisegroup.com/MonitiseUpdate/Images/linked_in_sig.gif]<http://www.linkedin.com/company/monitise>[Description: Description: Description: http://mailmedia.monitisegroup.com/MonitiseUpdate/Images/twitter_sig.gif]<http://twitter.com/#!/MonitiseGroup>

meta_back_db_open: no targets defined
by Matthew Bik 05 Dec '12

05 Dec '12

Hello, I hope this is the right forum for technical questions. If not I apologise in advance. I have been surfing for an answer for a while and was hoping that I am just missing something simple and someone can point me in the right direction. The scenario : I have several active directory domains where individual user accounts are managed. I am trying to setup slapd to use the meta backend so that my ldap server can act as a single sign on source for internal tools such as web pages, jabber, and the like. During the start of slapd it looks like I'm either missing something in my config or I have a typo that I haven't been able to find. To me, it looks like slapd won't start because I'm not giving it anything to do (no targets). I've also been using slaptest to convert a slapd.conf file since documentation on the cn=config files is a little hard to find. The Setup: - CentOS release 6.3 - openldap-2.4.23-26.el6_3.2.x86_64 - openldap-servers-2.4.23-26.el6_3.2.x86_64 The Error Log: Dec 5 08:20:56 example-host slapd[3487]: slapd startup: initiated. Dec 5 08:20:56 example-host slapd[3487]: backend_startup_one: starting "cn=config" Dec 5 08:20:56 example-host slapd[3487]: config_back_db_open Dec 5 08:20:56 example-host slapd[3487]: backend_startup_one: starting "dc=example,dc=com" Dec 5 08:20:56 example-host slapd[3487]: meta_back_db_open: no targets defined Dec 5 08:20:56 example-host slapd[3487]: backend_startup_one (type=meta, suffix="dc=example,dc=com"): bi_db_open failed!

My example becomes '... serialNumber 0x13E2, issuer ...' OpenLDAP follows the X.520 name comparison rules for the issuer name; you can switch case, change spaces into multiple spaces, add heading/trailing spaces, etc. I hadn't looked at the code yet to understand why asking for serialNumber 0x013E2 or 05090 doesn't match my certificates. -- Erwann.

RE: deleting all entries

Thanks for the quick reply. One more question, we have a master and couple slaves on the replication topology. Do I need to remove the files of all 3 servers individually?

Simply shut the server down and delete all files (possibly except the DB_CONFIGfile) in that directory.

Difference between 2.4.30 and 2.3.43 in certificateMatch.
by Mike Hulsman 03 Dec '12

Hi, I stumbled upon an difference between openldap 2.4.30 and 2.3.43. This is my configuration. X509 certificates are stored in the directory and a search is done with: (&(mail=aaa@a.b)(userCertificate:certificateMatch:=<binary certificate)) if that is a match the uid must be returned. That is working on 2.3.43 but when I try that on 2.4.30 it does not work and I start debugging I see filter="(&(mail=aaa(a)a.b)(?=undefined))" in the logfiles. The request is the same on both openldap servers, I copied the schema's and the acl's are the same. A slapcat on 2.3.43 is done and imported on 2.4.30 An ldapsearch on both servers for that user is returning the same data. Do I need some more configuration for the 2.4.30 version or am I doing something wrong. The 2.3.43 version is working properly, but I want to update to 2.4.xx for better replication. Kind regards.

deleting all entries
by jeevan kc 03 Dec '12

HelloWe are deleting all the entries from the Test ldap server and migrating the production data into the test server. I believe slapcat and slapadd would come handy for the migration part. But what I am concerned now is removing the entries from the Test server. How do I delete them ? I need to empty the server but then I want to keep the current configuration and schemas. My openldap on the server is built from the source and the DB files are located on /usr/local/var/openldap-data.Any ideas would be appreciated . Thank you.

Re: Index Add Failures
by Kyle Smith 03 Dec '12

Ok, I have been running 2.4.32 for some time with no issues. Yesterday, 2 different servers (both part of a 4-way MMR) produced an "index add failure" and an "index delete failure". I went back over the bdb DB_CONFIG Settings (listed below) and everything looks nominal to me. Would it just make more sense to switch from bdb to mdb instead of troubleshooting these "random" errors too much? I also noticed that the number of "deadlocks" corresponds to the number of errors that were produced. Is there correlation there?
