Syncrepl fails with LDAP_RES_INTERMEDIATE - SYNC_ID_SET
by Serge Dubrouski 25 Jan '09

25 Jan '09

Hello - I've had provider-consumer configuration working all right for about a month. Today I had to upgrade OS (RedHat 5) and restart services. After that one of my consumers failed with the following errors: Jan 24 19:32:54 rome slapd[2236]: do_syncrep2: rid=012 LDAP_RES_INTERMEDIATE - SYNC_ID_SET Jan 24 19:33:05 rome last message repeated 11 times And then started to delete records: Jan 24 19:33:40 rome slapd[2236]: syncrepl_entry: rid=012 be_modify (0) Jan 24 19:33:40 rome slapd[2236]: do_syncrep2: rid=012 LDAP_RES_SEARCH_RESULT Jan 24 19:33:40 rome slapd[2236]: do_syncrep2: cookie=rid=012,csn=20090125022613.018210Z#000000#000#000000 Jan 24 19:33:40 rome slapd[2236]: nonpresent_callback: rid=012 nonpresent UUID e7d215a2-3cc4-102d-8ea2-9f51782b1a5b, dn c=GB Jan 24 19:33:40 rome slapd[2236]: nonpresent_callback: rid=012 nonpresent UUID e7f0d37a-3cc4-102d-8ea3-9f51782b1a5b, dn o=....

To fix the problem I had to copy database from the provider to consumer and then restart that consumer. So what does that error mean and how to avoid it in the future? OpenLdap 2.4.13 DB 4.6-21 Thanks. -- Serge Dubrouski.

[OPENLDAP] slapd password confusion
by Technical Home 25 Jan '09

25 Jan '09

Hello, In my quest to install and understand how works a PDC Samba/OpenLDAP, I encountered a strange problem when setting my slapd admin password. Here is my server configuration : @(#) $OpenLDAP: slapd 2.4.11 (Oct 24 2008 23:44:05) $ buildd@palmer:/build/buildd/openldap-2.4.11/debian/build/servers/slapd I'm running ubuntu-server 8.10 Intrepid. My ubuntu is up to date. I installed the slapd package from ubuntu repository. dpkg asked me to specify a password for my admin account and I entered a password like this one : totototo12; And now when I try to modify my LDAP tree with the command "ldapmodify -x -D cn=admin,cn=config -W", at the password prompt, I can connect with all this password : totototo12; totototo12 totototo1 totototo totototo23 tototototo ... The only condition to login is that I wrote the beginning of my password : totototo Why slapd does not care about the end of my password ? If I specify a smaller password like toto12; in slapd configuration with dpkg-reconfigure, there is no problem... If you need more informations to help me to undersatnd what happens, just ask me ;) . Thanks in advance, Gilles

How can I *really* disable schema-checking?
by Salim Fadhley 24 Jan '09

24 Jan '09

I've recently inherited responsibility for an LDAP server for a large business critical operation. Unfortunately the previous developer simply added data with schema-checking off. They were using a very old version of OpenLDAP (which I can no longer use) which allowed them to disable all schema-checking. As a consequence the data is no longer compatible with the schema - all validation fails. I want to disable all schema-checking on my new server, so I used the slapd.conf directive "schemacheck off" - however this seems to be ignored. I know this because when I attempt to add an un-declared attribute to an entry in the database, the change is rejected. I understand that the "schemacheck" config directive has been deprecated in recent versions of slapd: But is there any other way to achive the same thing? I've been told that there is a class called "ExtensibleObject" - might this help? Please bear in mind that my database is big (approx 20Mb) and changing the data may break compatibility with the application. All I really want is to re-create the same kind of "anything-goes" platform that we had with the old 2.2.19 slapd which allowed me to disable all schema-checking. Thanks, Sal

Threads Backload
by Bill MacAllister 24 Jan '09

24 Jan '09

In looking at some load issues on our servers we have starting recording some cn=Monitor counters for analysis. In particular we would like to understand what cn=Backload,cn=Threads,cn=Monitor contains. On our servers we have threads set to 8 and we have seen maximum backload values of 56. Does this means there are 56 connections waiting for an execution thread?

OpenLDAP connecting to remote MySQL server with back-sql
by Jason B 24 Jan '09

24 Jan '09

Hi all, Question for you. I've been racking my brains over this one for most the day without much success, and it seems my Google-Fu is no match for this one. I'm hoping you can help. I'm attempting to setup OpenLDAP (2.4.13) with back-sql running as a module, relying on a MySQL server as a backend. My problem appears to be due to the fact I'm trying to run the database server on a remote host, not the same box as OpenLDAP. Attempting to start OpenLDAP gives the following error: ==>backsql_get_db_conn() ==>backsql_open_db_conn() backsql_open_db_conn: SQLConnect() to database "ldap" as user "dc1auth1" failed: Return code: -1 Native error code: 2002 SQL engine state: 08S01 Message: [MySQL][ODBC 3.51 Driver]Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) backsql_get_db_conn(): could not get connection handle -- returning NULL backsql_db_open(): connection failed, exiting However, obdc.ini (which has been separately tested) is configured to connect to the MySQL server on 192.168.1.34. My understanding is that the dbhost attribute in slapd.conf is ignored - we've set this anyway just to make sure. Extracts from each: Slapd.conf database sql suffix "dc=imagingthesouth,dc=com,dc=au" rootdn "cn=Hostmaster,dc=imagingthesouth,dc=com,dc=au" rootpw stat1c dbname ldap dbhost 192.168.1.36 dbuser dc1auth1 dbpass dc1auth1 subtree_cond "ldap_entries.dn LIKE CONCAT('%',?)" insentry_query "INSERT INTO ldap_entries (dn,oc_map_id,parent,keval) VALUES (?,?,?,?)" odbc.ini [ldap] Description = MySQL connection to Rhapsody Driver = MySQL DSN = ldap Host = 192.168.1.34 Server = 192.168.1.34 Servername = 192.168.1.34 USER = dc1auth1 PASSWORD = passgoeshere Database = rhapsody Port = 3306 Option = Stmt = I'm slightly out of my depth here - any assistance would be greatly appreciated! Many thanks, Jason.

schema checking
by Andreas Schoe 24 Jan '09

24 Jan '09

Hello, I installed and configured OpenLDAP to multimaster. The replication works great. But there is one problem: In Single Mode schema checking is still present. Since I configured to multimaster there isn't any schema checking. Example: In multimaster mode I can add multiple structural objecclasses to one entry. Is this a configuration problem? I read out that schema checking is always included. os: Solaris 10 8/07 s10s_u4wos_12b SPARC openldap: OpenLDAP 2.4.11 config: dynamic database: bdb olcOverlay: syncprov Best regards Andreas

Confused about configuring TLS
by Nathan Huesken 24 Jan '09

24 Jan '09

Hi, I want to use TLS on my slapd, which uses the slapd.d config way. On this page: http://www.openldap.org/doc/admin24/tls.html I find a discription of how to do it if one uses a slapd.conf. But how does it work with slapd.d? Thanks! Nathan

2.4.13, accesslog and logops
by Turbo Fredriksson 21 Jan '09

21 Jan '09

I just upgraded my 2.4 CVS from earlier this year to 2.4.13, but can't get the accesslog overlay to log _both_ reads and writes at the same time! Either one by itself works fine, but not combined. If I specify 'reads writes', all I get is reads. Same if I specify all the operation types ('add delete modify modrdn compare search abandon bind unbind'). Actually, not 100% true - I get the deletes, but nothing else (other than the read types).
