Help with roles
by antprado 14 Mar '10

14 Mar '10

(I did post this question to the software portion of the list also, my apologies if you seeing this in redundancy) Hi, I am being in contact with LDAP for the first and I do need to create a role for some users. Do you have any points or how to do this? What I need to do: role: ==> administrator user: admin001 role:==> developer user: dev001 user: dev002 role: ==> it user: operator001 user: operator002 I did create these accounts under fedora already. I need to create a role also for certain directories: for example: /home/bug ==> for developer /home/operations ==> for it /home ==> for administrator Thank you all for your help

How to make a simple bind using ldapv3?
by Thilko Richter 14 Mar '10

14 Mar '10

Hi, I am a litle bit confused: Do I use ldap_sasl_bind with null as mechanism or should I use ldap_simpl_bind, which is marked as deprecated in ldap.h? I cant´t find really helpful docs about this. Thx a lot, Thilko

RE: database is not a shadow

Ok, this is embarrassing. Issue: I'd set the provider to itself (on ldapmaster2): syncrepl rid=1 provider=ldaps://ldapmaster2.corp.aptimus.net type=refreshAndPersist interval=00:00:10:00 searchbase="dc=unix,dc=aptimus,dc=net" bindmethod=simple binddn="uid=root,ou=people,dc=unix,dc=aptimus,dc=net" credentials="Ten%20two" retry="15 20 60 +" mirrormode on changed to what it should be (ldapmaster1) and it started up fine.

Issues migrating from Linux passwd file to OpenLDAP
by Steve Cross 12 Mar '10

12 Mar '10

Hello all, Here is the issue that I am having. I have recently setup an OpenLDAP database for my local network. My goal is to use this for authentication for all clients on my network. I have been able to configure slapd.conf and the server will start up and run just fine. I have been using the migration tools to convert from the Linux style passwd file to .ldif files to import into my shiny new LDAP database. Everything goes smoothly, including the ldapadd command to import the ldif files. I am importing my users and my groups, as well as the base information for my site. Everything imports in, and i can find every user's DN using ldapsearch, but whenever I try to authenticate with any user imported from the passwd file, it fails authentication. However, if i go and change the user's password with ldappasswd then it will let me authenticate just fine for that user. I think this issue has to do with the fact that ldapadd automatically hashes the value stored in userPassword, but this seems to be causing issues with the SMD5 passwords that are stored in my shadow file. I've tried using {CLEARTEXT}, {CRYPT}, {MD5}, and {SMD5} before the value in the userPassword field, but no matter what i cannot login with the user's actual password. Is there any way to prevent ldapadd from hashing the userPassword value, since it already is encrypted? If not, what is the correct method for importing from passwd file that will not require me to change every user's password manually once imported into the LDAP directory. Below is my system setup. Slackware Linux 12.2 OpenLDAP 2.4.21 compiled from source passwd file encryption type: Salted MD5 If you need any more information please don't hesitate to ask. I am willing to provide any information necessary to get this going. Any help or pointers that I can get on this situation would be GREATLY appreciated. Thanks, Steve

OpenLDAP DB_CONFIG values for a big Server
by Echedey Lorenzo 12 Mar '10

12 Mar '10

Hi, Soon I'll have a x64 Suse machine with 16GB RAM and 4 Intel Cores. We need our OpenLDAP Server to be as fast as possible. I wonder which DB_CONFIG values are suitable for this. Maybe... set_cachesie 14 0 4 set_lg_regionmax 262144 set_lg_bsize 2097152 set_flags DB_LOG_AUTOREMOVE ...? Directory will have around 6~8 million entries. I'm not sure if they will be entirely uploaded to the RAM cache, but at least part of will improve speed, I think. Any help will be appreciated since my experiences with OpenLDAP performance against Sun Directory Server 5.2 has not been good, taking several seconds to answer any ldaprequest :( -- -------------------------------------------- | Echedey Lorenzo Arencibia | --------------------------------------------

Hi I have setup a multi master as per the online doco. When I was checking recently, the 2 DB were out of sync, some record hadn't been transferred over, I force this by setting -c rid=,csn= But whilst checking this, I noticed that some attributes haven't been moved across pwdFailureTime was on a record on the primary ldap server and not on the secondary master, try what I could I couldn't force it over is this a feature or a bug ?

I stepped through some source code in openLdap, but I dont know where the error code '-12' comes from and where to find some documentation. Thx a lot for help, Thilko

Is there an "authconfig" tool in ubuntu?
by Zengming Zhang 11 Mar '10

11 Mar '10

Hi everyone: In redhat system there is a tool named "authconfig" which is used to configure user authentication method on clients. What I want to know is that is there a similar tool in ubuntu system? I am going to set up a group system and all client computers are running ubuntu linux. I searched something use google, someone said that they are working on it. But the history of ubuntu is not short, someone must use some similar tools to change user authentication method on ubuntu. Anyone knows something about it? Please let me know! Thanks in advance. -- Zengming Zhang <nicegiving(a)gmail.com>
