Build it how you like, it's best to build from source to start with to get a feel for everything. Then depending on how you company works you can move to a commercially supported version. I would never recommend the RHEL version, but please visit the list archives for why. Thanks. -- Kind Regards, Gavin Henry. Managing Director.

Re: Re: N-Way Multi-Master replication - delete problem
by Adrien Futschik 15 Jan '09

15 Jan '09

It seems like I am not the only one facing this problem. Is this officially reported as a bug ? I found out that when deleting an entry on the master I added it to, it is removed only on this master and deleting is not replicated until I make some other operation on the other master. Seems like the delete is "queued". When deleting an entry on the "other" master (not the one I added the entry to), the delete works fine and is correctly replicated. Anyone to help me with N-Way Multi-Master replication ?

Hey All I am working on setting up sync replication for ldap. I have it working but I am not sure exactly what I can do with it. How do I failover to it?

OpenLDAP centralized authentication with Active Directory
by Duong Pham Tung (FIM HN) 13 Jan '09

13 Jan '09

Hello, My company network have some different domains such as abc.net, abc.com and xyz.com (I don't use real domain name because of our company's security policy). Each domain is managed by a dedicated Active Directory server. Now, I want to use one OpenLDAP server to authenticate all users from these domains because we want manage services they use focusly (such as Mail, Portal). But now, I have'nt any solutions to solve this problem. Because the number of users is very large (approximately 10.000 users) so I can't build database by hand. Can anyone suggest me the solution to solve this problem. Thanks and Best regards, Duong Pham.

OpenLDAP as a 'generic' hierarchical data store
by Lorenzo Pastrana 09 Jan '09

09 Jan '09

Hello list, I was wondering lately if I could use OpenLDAP as a 'generic' hierarchical data store for the application I'm planning, and tried to get any hint about feasibility. I found a blog post about OpenDS (http://blogs.sun.com/treydrake/entry/ldap_vs_relational_database), where the author states about Read/write performance parity ... That was the kind of news I just wanted to hear because I'm thinking about a persistence back-end, not just an almost static dataset, but I'm in a genuine PHP environment and Java is not an option; so I naturally tried to get some infos regarding OpenLDAP performance but found nothing recent, and the references I could find are quite discouraging on that matter ... However since 4 to 8 years have passed since the tests I've been reading, I'm still in the hope of a 'a pleasant surprise' as the sun guy sayz ... Does someone has an experience to share about that kind of (mis-)usage of OpenLDAP ? Any pointers to some good and recent reference on the matter are of course well come. Thanks in advance for any information.

Question about the manager acccount for the openldap-database
by Oliver Steffens 08 Jan '09

08 Jan '09

Hi together, Unfortunately the current (md5-encrypted) password is lost... Is it possible to change the "rootpw" in the "slapd.conf" from an md5-one into a new plain-text one without any problems respectively additional efforts? Thank you for your help in advance! Best regards Oliver Steffens
