19 June 07 - 15:11Free OpenLDAP for Windows Package Released

We at Symas have been watching a lot of folks struggling to build a stable OpenLDAP for Windows. After posting the last article about OpenLDAP on Windows, and since we had a recent version sitting on the shelf, we thought it would be nice to release it free of charge.

CDS Silver 3.7.1 for Windows (32-bit) is based on OpenLDAP 2.3.35 plus patches. It's been tested on Windows 2000, Windows XP, and Windows 2003 Server, and it's packaged in a nice InstallShield wrapper. Like all of our other OpenLDAP distributions, no other software is needed.

The package can be downloaded from CDS 3.x Silver Edition section of our download site. Check the release notes and the accompanying ReadMe file for additional information.

Enjoy!

13 June 07 - 13:53Red Hat Updates(?) OpenLDAP

In a security exposure announcement, Secunia tells us Red Hat has issued updated RPMs for Red Hat Enterprise Linux (RHEL) 3. They Red Hat has released a new RPM for OpenLDAP 2.0.27!? That was originally released in late September of 2002, going on five years ago. By any rational measure, that's ancient. Symas ships 2.3.35(?), less than a couple of months old, to subscribers and we're talking about HUGE performance, manageability, and reliability improvements in five years.

Sigh. ... Marty

PS: Marty's original note said August 2004, which is actually when 2.2.15 was released. I've corrected this. RedHat is, as usual, woefully out of date shipping something that was obsoleted several years ago.  -- Howard

13 June 07 - 04:28Undone by Yum!?

A sad story with a happy ending. This writer used Fedora's yum to upgrade OpenLDAP and it moved all his production data into a backup directory (without comment). Fortunately, he found it and was able to move it back into place and get things working properly again. You won't have that problem if you use Connexitor™ Directory Services (CDS), from Symas. We don't touch the database directory on upgrade. And our CDS packages are usually a lot more up to date.

04 June 07 - 03:57The multiprocessor capacity curve

In an intriguing email, we get some benchmark data. Symas's team members have experience with single memory multi-processor systems and this looks very normal, to a point.

The performance curves from one to 4 processors are pretty predictable. We see each processor adding less and less to four. Experience would indicate that with sufficient bandwidth to memory and memory performance, this should have continued to somewhere around 8 with the incremental performance improvement of each processor smaller than the last. We would have expected the tail-off above eight but clearly memory and OS-overheads got in the way for these machines at a much lower number of processors.

04 June 07 - 03:46CheckPoint Certifies OpenLDAP

Part of a trend. Customers are asking traditional Independent Software Vendors to certify that their LDAP products will work with OpenLDAP. We at Symas worked with HP to complete certification for their OpenView Identity Management products in 2006. Now we see Check Point certifying OpenLDAP 2.3.20, a relatively recent OpenLDAP Release, on Red Hat Enterprise Linux. (more)
