Hello, I have to deleted abount 500 Entrys under a OU in my LDAP-Tree cause I have to change the objectClass from "account" to "inetorgPerson". Can I do this with ldapdelete?

OpenLDAP server and OS X clients
by Arne Schmitz 11 May '09

11 May '09

Hi! We are running an OpenLDAP server on Debian Stable. It works very well so far, using more than 20 Linux clients. However, we now also have got a couple of Mac clients that are supposed to use the server. I have set the Mac clients (OS X 10.5.6) to use our LDAP server, using the Directory Utility. That utility is set to use a RFC 2307 server, with our LDAP's IP and the correct base name. After that I can "sudo su" to any LDAP user, also call "id" for any LDAP user, log in via SSH + key to LDAP user, but NOT authenticate via password. I.e. interactive logins or password based SSH logins are NOT possible. It seems the password authentication against LDAP is not working. What I find in /var/log/secure.log is the following: May 6 17:46:38 mymac authorizationhost[70401]: Failed to authenticate user MyLDAPUser (tDirStatus: -14090). Any ideas what might be going wrong here? Where should I look? Cheers, Arne -- Dipl.-Inform.

LDIF, userCertificate; and missing "binary" option
by Erwann ABALEA 07 May '09

07 May '09

Hello, Hoping it's the right list to ask for it. I'm facing a "cross-recommendations" problem. Here it is. I'm downloading an LDIF containing some inetOrgPerson and cRLDistributionPoint entries, in order to have a replication site to develop on. Those entries have userCertificate or certificateRevocationList , but not stored with the "binary" option (only the "::" indicating it's Base64-encoded). When trying to import this file with ldapadd on my directory, it failed, telling me that those attributes need to be transfered with the binary option. Right. I'm searching RFCs 2252 and 2256 (and their replacement as well), and find that effectively, those attributes *MUST* be transfered as binary ones. I told the directory maintainer that the LDIF wasn't correct according to these RFCs, and he replied that it was correct regarding RFC2849, which is the only one defining the LDIF format. Finally, that's right. And this RFC doesn't tell anything about certificates or binary option. And I can't find an obvious link between RFC2849 and RFC2252/2256. I know I can just do a 'sed s/userCertificate::/userCertificate;binary::/' of the file, but modifying something defined to be a standard for interchange doesn't seem to be a good solution. Do you have some ideas? Regards. -- Erwann.

OpenLDAP multi master replication
by Bujji S 07 May '09

07 May '09

Hi, i have openldap(2.4.9) installed in ubuntu 8.04 server. i want to create a multi master set up with two such servers(2 or more than 2) first i tried to follow http://www.openldap.org/doc/admin24/replication.htmlto form n-way master setup. but in starting only i got a problem saying database(dc=mytest,dc=com) is not configured to hold "cn=config" then i tried setting up cn=config using http://www.zytrax.com/books/ldap/ch6/slapd-config.html but that doesn't help me meaning even after configuring that cn=config as he mentioned in the site i got the same error so i removed everything(slapd.d) what i did earlier so now i have slapd.conf in both of my servers finally i found one more link http://itsecureadmin.com/wiki/index.php/OpenLDAP_Multi-Master_Replication that displays sample config file so i followed that you can check the slapd.conf below so now i set up the same configuration in the second server too. after writing these slapd.conf i just restared slapd on both servers. for the first time when i add some data the first server it got replicated on the other server only when restart slapd on second server. that is fine. when i tried to add some other data on second server its not getting replicated on the other server even if i restart slapd. after that wherever i add data not getting replicated adding locally only. what could be the problem. plz check my slapd.conf file and suggetst me how to do multi master replication on ubuntu 8.04 server. so my slapd.conf is below. # This is the main slapd configuration file.

ldap users in local groups
by Justin Lintz 06 May '09

06 May '09

Hi, I'm running into an interesting problem in that when I try to add more than one ldap account to a local group, both users of that group no longer show membership in that group when running "groups" or "id". If I just add one of the users to the group, it works without a problem. I apologize if this is not the correct list of this issue. Does anyone have any ideas on what may be causing this? - Justin Lintz

Occasional corrupt DN in be_add logs under 2.4.16
by Sean Burford 06 May '09

06 May '09

Hi, As an interim measure while deploying 2.4.16 I am canarying 2.3.43 on a replication provider. As a result the current replication path is: master (2.3.39) -> provider (2.3.43) -> replica (2.4.16) The master will be upgraded in short order once the 2.3.43 canary is successful. I've been seeing occasional corrupt DNs in some be_add log lines on the 2.4.16 replica: May 5 09:35:46 host slapd[31817]: syncrepl_message_to_op: rid=100 be_add <90>Y1 ntry,ou=subtree,dc=example,dc=com (0) I've modified the DN in this log line. The missing text is "cn=l" in this example. The original DN was 65 characters long. I have performed the following search against each host with the following results. It shows that the entry replicated fine but capitalisation of the DN differs (which may be a red herring since I was already aware that DN capitalisation differed across servers): $ ldapsearch -x -b cn=lntry,ou=subtree,dc=example,dc=com -s base dn master: dn is cn=lntry,ou=Subtree,dc=example,dc=com provider: dn is cn=lntry,ou=subtree,dc=example,dc=com replica: dn is cn=lntry,ou=Subtree,dc=example,dc=com slapcat shows no problems with the entry on the 2.4.16 host. Since the database looks fine I wonder if this is just a logging issue. Should this Debug statement in syncrepl.c actually use op->ora_e->e_name.bv_val or some other attribute? rc = op->o_bd->be_add( op, &rs ); Debug( LDAP_DEBUG_SYNC, "syncrepl_message_to_op: %s be_add %s (%d)\n", si->si_ridtxt, op->o_req_dn.bv_val, rc ); With the exception of si->si_rid becoming si->si_ridtxt (and %d->%s) this Debug statement has not changed since 2.3. -- Thanks, Sean Burford

slapd-meta and paged results control
by Lajos Boróczki 06 May '09

06 May '09

Hi, I'm trying to set up an openldap proxy server using slapd-meta. Everything worked so far, but after the backend database grew bigger and bigger, searches with a fixed page size started to give strange results. Tracing the problem led me to the following: If I set a page size of 300 in my ldapsearch (where localhost:3890 is my slapd running slapd-meta): ldapsearch -x -W -D "CN=admin,DC=example,DC=org" -E pr=300 -H "ldap://localhost:3890/" -b "dc=a,dc=example,dc=org" "(objectClass=inetOrgPerson)" uid I get at most 300 results and the paging information is lost on the way. If I set 300 to 1000 I get all of the results, because I have ~500 entries. Doing an ldapsearch to the backand servers: ldapsearch -x -W -D "CN=admin,DC=example,DC=org" -E pr=300 -H "ldap:// dc1.a.example.org/" "dc=a,dc=example,dc=org" "(objectClass=user)" userPrincipalName I get 300 results and a prompt to press enter, after pressing some enters I can get every entries. My backends are Active directories... :( Thanks for your help, Lajos Config: include /etc/ldap/schema/core.schema include /etc/ldap/schema/cosine.schema include /etc/ldap/schema/ad_attr.schema include /etc/ldap/schema/ad_class.schema pidfile /var/run/slapd/slapd.pid argsfile /var/run/slapd/slapd.args loglevel 8 modulepath /usr/lib/ldap moduleload back_meta moduleload back_ldap moduleload rwm moduleload pcache moduleload back_bdb sizelimit 1000 tool-threads 1 database meta suffix "dc=example,dc=org" norefs yes rebind-as-user yes chase-referrals no uri "ldap://dc1.example.org/dc=example,dc=org" "ldap:// dc2.example.org/" uri "ldap://dc1.a.example.org/dc=a,dc=example,dc=org" "ldap:// dc2.a.example.org/" uri "ldap://dc1.b.example.org/dc=b,dc=example,dc=org" "ldap:// dc2.b.example.org/" overlay rwm rwm-rewriteEngine on rwm-map attribute uid userPrincipalName rwm-map objectclass inetOrgPerson user

ppolicy pwdcheckmodule...
by JDaniel Jimenez 06 May '09

06 May '09

Hello everyone, I have installed openldap about two months ago, everything went ok and now I need passwords policies. Theese are working as spected but pwdCheckModule. In `man slapo-ppolicy` I have read this is an user-defined module... This is a problem for me... A long time ago I think I was able to do this without too much problems but now by now I must read "C++ Bible" to understand this... Is there any sample, or configurable module for this? Every body do this bi itself? thanks in advance ;) -- JDani

[Openldap2.4.11-Ubuntu8.10] Configuration Problem: ldap.conf missing, not possible to create slapd.d using slaptest
by Ket Zal Dev 06 May '09

06 May '09

Hi All I'm on Ubuntu 8.10, and using openldap 2.4.11. I successfully installed openldap on my server. I was a little bit surprised because i didn't found slapd.conf on /etc/ldap/ like in older releases, but I found a tuto explaining how to use slapd.d. On this howto, they sepcified it is possible to convert slapd.conf to slapd.d using slaptest. Because I don't have slapd.conf, I cannot convert anything. So, How can I do??? Secondly, on the tutorial, I used slaptest to create a ldif for a schema. I successfully added the ldif schema to openldap using ldapadd, and schema is working. It was mozillaorgperson, and I'm now able to create, read and modify users. My problem is that I need to use a new schema "rfc2703bis.schema" because my openldap server is for egroupware, and there is a problem with PosixGroup...... So I need to add it. This schema should replace nis schema. BUT, I cannot delete NIS schema, because used by open ldap. And cannot add rfc2703bis because I have errors "already exists" <--- it is logical because entries are on NIS which is active on openldap at this time. So I tried a lot of things, like using slaptest to create de ldif, copying it widely to slapd.d and removing by hand the NIS schema.... Not working, the result is that now, the openldap server cannot start.... Is there a clean way to do that??? Is it possible for me to create a slapd.conf, put inside all my configuration, do the slaptest, have a clean slapd.d and run openldap???? in a simple way. What to put inside...??? Thanks a lot for you help Best Regards
