If this works I delete all entrys and add them with the right ObjectClass.

Newbie planning for the future
by Alex Moen 21 May '09

21 May '09

Hi all, I am a newbie to LDAP, and have just gotten my first directory server up and running, using openldap. I have been researching and reading a lot of material for quite a while about schema design and planning, and haven't found much pertaining to what I want to do. We have 50+ servers, serving thousands of customers. I want to migrate those servers to LDAP authentication and authorization, but have not found the proper design for multiple servers and duplicated users. Most references just do the basic "example.com" example and never expand on it from there. Ultimately, I would like to allow my admins to have a single account across multiple servers (kind of "authorization account merging"), but still allot the schema to be "separate" enough that duplicated usernames on different machines, corresponding to different people, still exist. Are there any really good references out there that do step-by-step walk throughs of the type of schema designing that I am thinking of? Or is it impossible? Or am I just really making too much of this? :) Thanks for any insights... Alex

unable to add certain entries

19 May '09

I'm having a growing problem where certain entries won't add and I get these errors in slapd stats output: conn=7 op=160 MODRDN dn="cn=Untitled_1,cn=computer_groups,dc=chetwood,dc=local" => bdb_dn2id_add: subtree (cn=mslib,cn=computer_groups,dc=chetwood,dc=local) put failed: -30996 conn=7 op=160 RESULT tag=109 err=80 text=DN index add failed conn=7 op=161 MOD dn="cn=Untitled_1,cn=computer_groups,dc=chetwood,dc=local" conn=7 op=161 MOD attr=cn entry failed schema check: value of naming attribute 'cn' is not present in entry conn=7 op=161 RESULT tag=103 err=64 text=value of naming attribute 'cn' is not present in entry conn=7 op=162 MODRDN dn="cn=Untitled_1,cn=computer_lists,dc=chetwood,dc=local" => bdb_dn2id_add: subtree (cn=mslib,cn=computer_lists,dc=chetwood,dc=local) put failed: -30996 conn=7 op=162 RESULT tag=109 err=80 text=DN index add failed conn=7 op=163 MOD dn="cn=Untitled_1,cn=computer_lists,dc=chetwood,dc=local" conn=7 op=163 MOD attr=cn entry failed schema check: value of naming attribute 'cn' is not present in entry conn=7 op=163 RESULT tag=103 err=64 text=value of naming attribute 'cn' is not present in entry conn=7 op=164 SRCH base="cn=computer_groups,dc=chetwood,dc=local" scope=2 deref=0 filter="(&(objectClass=posixGroup)(objectClass=apple- group)(objectClass=extensibleObject)(|(cn=untitled_1)))" conn=7 op=164 SEARCH RESULT tag=101 err=0 nentries=1 text= conn=7 op=165 ABANDON msg=165 This is slapd 2.3.27, which is included in Apple OSX 10.5. This particular entry is for a computer group called mslib, and I'm using Apple's workgroup manager tool to add it. Other names will add, it seems to be entries that were created before but aren't showing up now. This is also happening for other object classes, like computer entires. slapcat and the other tools I use don't show an existing entry for mslib or the other names that won't add. Any advise on where to go from here would be appreciated. Thanks, Andy Zirkel.

Host based authentication using OpenLDAP
by Per Kristiansen 19 May '09

19 May '09

Hello, I've been working on implementing a LDAP solution for the last 8 months (in-between task, you know how it is :D ) I now have a working LDAP directory, have all my users imported, things actually work! :D..(jinx!) But now I wanna get fancy.. I've been googeling for some sort of clear description on how I can set up a system using groups of hosts and user groups to create a selective ACL for ssh'ing to a set of servers based on group membership. One of my primary goals is to have it work as much "out of the box" as possible for RHEL4 and 5 (and CentOS ) That means I want to avoid having to make changes to hosts (I have around 60-80 linux servers today that I want over on LDAP) So I try to avoid the solutions involving /etc/security/* I have it working with the ldapns schema with no changes to PAM. But this means I have to enter the specific host into each user record. But I'm a contrary and difficult guy, and love making problems for my self so I want to assign groups of users to groups of servers. Oh..and SSH keys :D..but that is for when life looks sunny and I need to be reminded that the world is a bad place. is there anyone that can point me towards resources that are written on this?..I already have a list of links I've been reading, and are adding those here in case other people want to look at them: https://help.ubuntu.com/community/LDAPClientAuthentication http://www.redhat.com/f/pdf/rhas/NetgroupWhitepaper.pdf http://www.padl.com/OSS/nss_ldap.html http://www.padl.com/OSS/pam_ldap.html http://quark.humbug.org.au/publications/ldap/system_auth/sage-au/system_aut… Thanks for taking the time to read this :) -- Per

Jabber and LDAP
by Gavin Henry 19 May '09

19 May '09

Hi All, Does anyone have any recommendations on Jabber servers that have great LDAP support and a small-ish footprint (i.e. not OpenFire)? I've been looking at http://xmpp.org/software/servers.shtml eJabberd and jabberd2 are the ones I've once used. Thanks.

MMR get inconsistent when updating entries concurrently to both Masters(2-masters configuration)
by hu zhang 18 May '09

18 May '09

Hi, all, I set up a testing environment for the MMR(2 master server), it did work well when I tested it in a "test050" style, that was, send updated requests to one of the master server, waited for seconds, then send update requests to another master server. All updates could be properly replicated among both servers. However, when I tried to update entries in an interleave style to these servers, I mean, like, the first update request was sent to server A, and the second request was sent to server B, then A, then B, .... there was no waitting between the update requests, and all requests were differnt. >From my understanding of the MMR, I hoped all updated in server A would be finally replicated to server B, and same to server B. But, the real test result was, I could see all updates in one of the server, but only partial updates in another server, the partial updates were exactly made by the requests directly comes to that sever, that is to say, the replication samed to be *monodirectional *in this situation. My question, is this scenario a bug for current openLdap, or, it is just not a supported use case ?* * I've been trying to find an answer in past mail threads, but I failed. Hope you guys can help me out from this confusion about MMR, if you need any further information, like configuration, I'll put them on, but I don't think that's a configuration problem, because the "test050" style testing works. Thanks! Hu

authenticate group of hosts
by François Mehault 18 May '09

18 May '09

Hi All, I have install openldap to authenticate users on system Unix. So, I use the module pam_ldap / nss_ldap with primitive pam_check_host_attr yes, and I have the attribute host for each person in my LDAP. I want to have 3 levels of authentication : - First level : a person have numerous attributes « host » so he is able to authenticate on these hosts - Second level : a person could be able to authenticate on a group of host - Third level : a person is able to authenticate on all hosts For the first level, for each host I declare one primitive « host » for my user in openldap : dn: cn=Francois MEHAULT,ou=Utilisateurs,dc=netplus,dc=fr givenName:: RnJhbsOnb2lz sn: MEHAULT uid: fmehault cn: Francois MEHAULT homeDirectory: /home/fmehault loginShell: /usr/local/bin/sh gidNumber: 1203 uidNumber: 1203 objectClass: inetOrgPerson objectClass: posixAccount objectClass: top objectClass: hostObject userPassword: {MD5}9x2+UmKKP4OnerSUgXUlxg== host: labobe1 host: labobe2 For the third level, I put just the primitive « host : * » But I don't know how i could do the second level. I would like something like groupRadiusName, I want to define numerous group with host primitive, and each users can be in one group or plus. The goal is that my user have his host primitive plus the host primitive of his group. Is it possible ? Thanks for your help, Regards, François

getting rid of "request done" messages
by Heiko Petzsch 18 May '09

18 May '09

Hi, I've tried to ask the following question in the openldap-software mailing list: > I have a beginners question: when I log in as root on one of my systems, I > get quite a lot of messages of the form > > request done: ld 0x5654f0 msgid 1 > request done: ld 0x5654f0 msgid 2 > ... > > on the console. I assume that they originate from my openldap installation > - but I don't even understand the mechanism how they are send to me > (openldap was installed by my predecessor). Could someone please tell me > how to get rid of these messages ? The moderator rejected my question, giving as his reason: (I hope he doesn't mind being quoted with this) "Given these messages occurred when you "log in", it is likely that issue relates to LDAP client software you are using to manage system log ins. Your question of "how to get rid of these" is likely lead to off-topic discussion of that LDAP client software. However, your message does at seem to relate to the use of OpenLDAP Software, hence it suggested you submit your submission to the OpenLDAP-technical list." I must admit that I had and have have no certainty at all which software produces these messages - I only searched the internet, and saw the same messages in connection with questions other people asked about openldap. They are, though, not a direct result of me logging in - they arrive continously and even after hours of being logged on. Could anybody tell me where these messages originate from, and how I can disable them ? Any help will be appreciated. Heiko -- Heiko Petzsch GTS Systems and Consulting GmbH D-52134 Herzogenrath
