To which objectclass should the entry belongs to ? What about access rules ?

OpenLDAP mirror replication ldif format
by Simon Massart 30 Jun '11

30 Jun '11

Hi there, I recently installed a new Debian 6 and OpenLDAP to test the new ldif format configuration. The problem is that I do not have any base configuration to use slaptest to migrate my config to ldif format. My main concern is now to find a manual/tutorial, to be able to setup a mirror replication with ldif format, because all I can find is using the old slapd.conf. Can anyone point me somewhere, where I could find some help or give my a quick example ? Thanks in advance for any return, Sismon

autofs wild cards
by Collins, Cris 30 Jun '11

30 Jun '11

My auto.home has "* host:/export/&" for user directories. When I use the automount migration tool the * is changed to / and I get the error: adding new entry "cn=/,ou=auto.home,dc=domain,dc=com" ldapadd: Naming violation (64) additional info: value of naming attribute 'cn' is not present in entry Is there a way to get the wild card to work or do I need to enter each user instead of using a wild card? Thank you for your time.

pcache + back-sql
by Chris Card 30 Jun '11

30 Jun '11

[Let's try that again. Hotmail/Chrome managed to screw up the formatting before] Does anyone have an example of using the pcache overlay with back-sql? Here's the relevant section of my slapd.config: database sql suffix "......" rootdn "......." rootpw ........ dbname MySQL dbuser ......... subtree_cond "ldap_entries.dn like CONCAT('%',?)" insentry_stmt "INSERT INTO ldap_entries (dn,oc_map_id,parent,keyval) VALUES (?,?,?,?)" has_ldapinfo_dn_ru no baseobjectupper_func UPPER autocommit yes pcache bdb 10000 1 50 100 pcacheAttrset 0 * + pcacheTemplate (objectClass=) 0 60 ... pcache-directory /var/tmp/cache pcache-cachesize 100 What I'm unclear about is how to configure the private bdb database used for the cache. When use this config, slapd starts up ok, but crashes with a SEGV when (I assume) it tries to cache a result: (I am running slapd built from the latest code in HEAD from git) slap_queue_csn: queing 0xb7a52efa 20110629132038.554471Z#000000#000#000000 Program received signal SIGSEGV, Segmentation fault.

This leads me to believe that I need something in slapd.conf to get the private bdb database initialised, but what? Chris

fetching information
by Friedrich Locke 30 Jun '11

30 Jun '11

I am planing using openldap to fetch user/group information. Below my main tree there will be ou=people and ou=group, and below those the regular user or group information. It happens that a program (ypserv) will fetch information from tree binding as cn=ypserv just below my main tree. This binding should be authenticated, so what should cn=ypserv attributes be? What about access rules for it ? Thanks a lot for your time and cooperation. Best regards! Fried.

I would like to see how many connections openldap is serving on a given momment. I am trying this: sioux@gustav$ ldapsearch -LLL -W -D cn=oldap,dc=ufv,dc=br -b cn=current,cn=connections,cn=monitor -H ldap://gustav.cpd.ufv.br/ objectclass=* Enter LDAP Password: dn: cn=Current,cn=Connections,cn=Monitor objectClass: monitorCounterObject cn: Current sioux@gustav$ I cannot see the number of connections. Where is my mistake ? Thanks a lot.

protected entry
by Friedrich Locke 29 Jun '11

29 Jun '11

Dear list users, i would like to have an entry in my openldap server thats needs to have a password so that it would be able to permit clients to bind as it providing its password. For instance: cn=x,ou=y,dc=a,dc=b So anyone knowing "cn=x,ou=y,dc=a,dc=b" 's password could bind as it. Any ideia? Thanks.

chaining through proxy and slave
by Hugo Monteiro 29 Jun '11

29 Jun '11

Hello list, With the following scenario Client (A) <-----> back_ldap Proxy (B) <-----> syncrepl Slave (C) <-----> Master (D) and B and C use a binddn that only has full read permissions on the database, except for a couple of attributes, on which it has full write permissions. Also, Each of the represented nodes can only "talk" to the nodes to which there is a represented connection, so (A) and (B) cannot chase a configured referral to (D). What would be the proper way to setup (B) and (C) so that (A) could push updates for the couple of attributes into the master (D) node? At the Slave level, i've already setup chaining and making it use (D) as updateref, but then any push on (B) would not propagate. I also noticed that in although i used mode=self, in the chaining, i had to configure a binddn which had full write permissions. Wouldn't it be sufficient to have a full read enabled binddn or even no binddn at all since the bind would then be made using the clients credentials? Thanks in advance, Hugo Monteiro. -- fct.unl.pt:~# cat .signature Hugo Monteiro Email : hugo.monteiro(a)fct.unl.pt Telefone : +351 212948300 Ext.15307 Web : http://hmonteiro.net Divisão de Informática Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa Quinta da Torre 2829-516 Caparica Portugal Telefone: +351 212948596 Fax: +351 212948548 www.fct.unl.pt apoio(a)fct.unl.pt fct.unl.pt:~# _
