Re: OpenLdap unstable on RHEL5 & Centos5 with db4

Thanks, i downloaded RPMS from the link you send me but if i remove the original RPMS i have a lot of dependencies one of them is postfix. It gives libldap errors. So what i did was i recompiled postifx on a system having the new ldap rpms installed and used that postfix rpm on my setup. This solved the issue. I had to make changed in the DB_CONFIG file to match the cache size suited to my systems memory and also copied the same file to some of the application which need the DB4 library like /var/imap/db .This solved 99% of my problems.

You went about it one of the ways possible; however, installing Buchan's rpms will mean that they exist *parallel* to Red Hat's, so Red Hat's offerings don't have to be removed. I'm guessing that their are dependencies to the Red Hat client stuff and keeping these will obviate the remaining 1% of your problem. In fact, I have exactly the same on one of the RHEL5 servers on my site, where I can't use Buchan's client rpm and have to use Red Hat's.

OT: I hope you discovered Simon J. Mudd's Postfix srpm, since it enables you to upgrade Postfix to latest stable (d.d. 2.5.1)

I am running Openldap and db4

[root@build ~]# slapd -V
@(#) $OpenLDAP: slapd 2.3.27 (Mar 14 2007 17:44:50) $

DB4 vcersion db4-4.3.29-9

We have a address book containing around 500 to 2000 addresses stored in it. Every thing works fine for some days and then it crashes. I see nothing in the logs. We are using a custom schema attached with this email. Before we upgraded from the default openldap in centos4.4 to Centos5.0 it was working perfectly, is there any compatibility issues with the schema & the new package.

Indeed; this is Red Hat's version of OpenLDAP which is basically unstable and runs a deprecated db4 version. Believe me you are not the first person to experience this and you will not be the last. Moreover, however many backports Red Hat / CentOS will do of it in the future it can, by definition, never get any better.

 I'm a RHEL5 sysadmin and this is not a new matter for Red Hat sysadmins.

Install the packages at http://staff.telkomsa.net/packages/rhel5/openldap/ and you'll be set to go.
