one user access all databases
by Hendrik van der Ploeg 22 Mar '11

22 Mar '11

Hello, Can I add 1 user in cn=config so that it can access all the underlying databases? (olcdatabase={1}bdb, olcdatabase={2}bdb etc. The reason for this is that I use ldap-meta which connects to a LDAP server with multiple databases in it. dc=0001,dc=domain,dc=nl dc=0002,dc=domain,dc=nl dc=0003,dc=domain,dc=nl I use "idassert-bind" at the ldap-meta server to set a different username. But in this situation I need to add an extra username for every database in slapd.conf Is there a possibility to use a global user which can access all the databases? Thanks in advance Regards, Hendrik The Netherlands

OpenLDAP Memory Usage
by Diego Lima 22 Mar '11

22 Mar '11

Hello all, I'm experiencing some problems with some OpenLDAP servers: the slapd process seems to always use more memory, eventually reaching a point where it has consumed all the available server memory and is killed by the OOM killer. The servers have 32gb of memory plus 32gb of swap space and are running Debian Lenny (with kernel 2.6.26-2-amd64), and we have compiled OpenLDAP 2.4.23 from source, and we're using Berkeley DB 4.6. The servers are dedicated to running OpenLDAP, so they don't have other processes that use a significant amount of memory. This is a relatively high-volume environment, with 4 servers running with mirrormode to enable multi-master replication. The current database size is about 900mb. Is there any setting that could limit this memory usage? I don't feel this is "normal" considering our DB size and cache sizes. These are my slapd.conf and DB_CONFIG files: --------------------------------- slapd.conf --------------------------------- disallow bind_anon require authc #== Schemas snipped == pidfile /usr/local/openldap/var/run/slapd.pid argsfile /usr/local/openldap/var/run/slapd.args loglevel 16640 modulepath /usr/local/openldap/lib/ldap/ moduleload back_bdb moduleload ppolicy moduleload syncprov threads 8 database config rootdn "cn=admin,cn=config" rootpw {SSHA}PASS database monitor rootdn "cn=admin,cn=monitor" rootpw {SSHA}PASS database bdb suffix "dc=corpldap,dc=mycompany" rootdn "cn=admin,dc=corpldap,dc=mycompany" rootpw {SSHA}PASS directory /usr/local/openldap/var/corpldap-mycompany-data overlay ppolicy overlay syncprov ppolicy_hash_cleartext syncprov-checkpoint 100 10 syncprov-sessionlog 100 monitoring on lastmod on checkpoint 512 10 cachesize 200000 idlcachesize 600000 #== Indexes and ACLs snipped == serverid 1 syncrepl rid=002 provider="ldap://server02:389" searchbase="dc=corpldap,dc=mycompany" type="refreshAndPersist" retry="30 10 60 15 600 +" bindmethod=simple binddn="cn=repuser3,ou=replica,dc=corpldap,dc=mycompany" credentials="PASSWORD" #== other syncrepl entries snipped mirrormode on --------------------------------- DB_CONFIG --------------------------------- set_lg_max 10485760 set_lg_regionmax 1048576 set_lg_bsize 2097152 set_lg_dir /var/ldap/corpldap-mycompany-log set_flags DB_LOG_AUTOREMOVE set_cachesize 0 2073741824 0 set_lk_max_objects 5000 set_lk_max_locks 5000 set_lk_max_lockers 5000 -- Diego Lima http://www.diegolima.org

DSEE to OpenLDAP
by adam＠spoontech.biz 21 Mar '11

21 Mar '11

Hi, I have currently been given the task of migrating our current LDAP environment from Sun DSEE (6.3.1) to OpenLDAP. I have done some research on this topic, and suspect its not a trivial task, and am hoping for some pointers/advise from anyone that may have attempted this in the past... I'm not sure that replication between the two is an option (although would love it if it was :), so I have looked into exporting the current DSEE environment to a LDIF, and attempted to then import it into openldap (using slapadd), but ran into a few issues... The issue I'm currently stuck on is getting the data in the LDIF into a format that can be imported using slapadd. Currently, I have issues with automounts, pwdReset attribs etc etc... Any help would be appreciated. Cheers,

Fw: Trying to start Slapd, bad conf file.
by Noel Akins 21 Mar '11

21 Mar '11

Hi, When I try to start slapd I get a failed message saying the config file is bad. What I have below is what was uncommented in slapd.conf as it came in the package. I installed Openldap via yum on my 1and1 VPS which has CentOS. It would seem that the Openldap package for CentOS puts things in different places then in other distributions, and it also seems that this conf file is a bit more complex then what I see in introductory material on LDAP/Openldap, which isn't helping me to learn this. I'm wanting to use ldap to authenticate users on a website, and to ultimately use Shibboleth to federate logins (which requires ldap). I'm new to this and I'm not sure what the problem is with this file. One thing I wanted to ask was since I'm looking to use ldap for website authentication, do I need these schema's? I know I can create a local schema which I think is what I need to do for my purpose. If you have any suggestions or can point out what is wrong here, I would greatly appreciate it. Thank you. ######################################################################### include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema # Allow LDAPv2 client connections.

syncrepl consumer with several providers, is it working?
by LALOT Dominique 21 Mar '11

21 Mar '11

Hello, I'm a little bit worried about that mail and the fact that our setup is getting out of sync sometimes. http://www.openldap.org/lists/openldap-software/200505/msg00324.html versions: the providers are all 2.4. The consumer is 2.4.23, some providers 2.4.21 one 2.4.11 And our setup is not stable, we get out of sync, it's a matter of days/weeks. So, is this working? Should we prefer a relay, then replicate from the relay. What is the right solution? Is there a simple way to force replication whithout deleting the database? Should I replicate to 4 databases and create refererals, then replicate the whole tree to another consumer? Thanks in advance for any advice Dom Our configuration on the fusion consumer: database bdb suffix "dc=fr" syncrepl rid=010 provider=ldap://ldapmaitre.univ-xx.fr/ type=refreshAndPersist searchbase="dc=univ-xx,dc=fr" retry="60 10 300 +" scope=sub filter="(objectClass=*)" attrs="*,modifytimestamp,modifiersName,createTimestamp,creatorsName" schemachecking=off bindmethod=simple syncrepl rid=011 provider=ldap://ldapmaitre.univ-yy.fr/ type=refreshAndPersist searchbase="dc=univ-yy,dc=fr" retry="60 10 300 +" scope=sub filter="(objectClass=*)" attrs="*,modifytimestamp,modifiersName,createTimestamp,creatorsName" schemachecking=off bindmethod=simple syncrepl rid=012 provider=ldap://annuaire.univ-zz.fr/ type=refreshAndPersist searchbase="dc=univ-zz,dc=fr" retry="60 10 300 +" scope=sub filter="(objectClass=*)" attrs="*,modifytimestamp,modifiersName,createTimestamp,creatorsName" schemachecking=off bindmethod=simple syncrepl rid=013 provider=ldap://annuaire-maitre.univ-ww.fr/ type=refreshAndPersist searchbase="dc=univ-ww,dc=fr" retry="60 10 300 +" scope=sub filter="(objectClass=*)" attrs="*,modifytimestamp,modifiersName,createTimestamp,creatorsName" schemachecking=off bindmethod=simple -- Dominique LALOT Ingénieur Systèmes et Réseaux http://annuaire.univmed.fr/showuser.php?uid=lalot

how ldap works replicating AD?
by Lumeng Lim 21 Mar '11

21 Mar '11

am new to this but is familiar with the purpose of ldap. I just can't visualize how it works. What we would want to happen is have linux desktops to authenticate with a linux server to be able to gain access to network resources. currently. We have linux server with samba as PDC and windows clients that connect to network shared resourced. Users just login via the "domain" and network drives are mapped. When server is unavailable (in cases of laptops) user just logs in and work with the local resources We would like to have the same thing going with linux desktops and laptops. With LDAP how is this implemented? Hope someone can help us visualize so we know what softwares and configurations should be done in the side of both the server and the clients.

Re: Error code 65 - invalid structural object class chain (groupOfUniqueNames/posixGroup)]
by Casey Jordan 20 Mar '11

20 Mar '11

Quanah, Thanks for the quick reply. I understand this, however the tutorial I am following seems to require it: http://demo.exist-db.org/exist/ldap-security.xml They say "Each group is represented by a single entry under the groupDN as a union of RFC 2307 posixGroup and RFC 2256 groupOfUniqueNames." If this is indeed a requirement for these systems to talk to each other do I have any other options?

Understanding back_perl SampleLDAP.pm
by Marco Pizzoli 20 Mar '11

20 Mar '11

Hi list, could someone help me in understanding what the SampleLDAP.pm perl module do in its search routine? This is the code: -------- sub search { my $this = shift; my ( $base, $scope, $deref, $sizeLim, $timeLim, $filterStr, $attrOnly, @attrs ) = @_; print {*STDERR} "====$filterStr====\n"; $filterStr =~ s/$|$//gm; $filterStr =~ s/=/: /m; my @match_dn = (); for my $dn ( *keys %{$this}* ) { if ( $this->{$dn} =~ /$filterStr/imx ) { push @match_dn, $dn; last if ( scalar @match_dn == $sizeLim ); } } my @match_entries = (); for my $dn (@match_dn) { push @match_entries, $this->{$dn}; } return ( 0, @match_entries ); } -------- I'm interested in knowing what "keys %{$this}" should contain and why, in trying to use this sample perl module I cannot see any "key" of the array variable $this. I configured the database in this way: database perl suffix "dc=perl,dc=com" perlModulePath /tmp/appoggio/ perlModule SampleLDAP Thanks in advance Marco
