I might as well start easing back into the OpenLDAP Weekly Newsletter by doing some "OpenLDAP Quick Tips". Here's the first one.
"Check that the synchronisation state indicators of any slaves or masters are the same":
[ghenry@suretec ~]$ ldapsearch -x -LLL -H ldap[?]://master:389 -s base -b 'dc=suretecsystems,dc=com' contextCSN[?]
[ghenry@suretec ~]$ ldapsearch -x -LLL -H ldap://slave:389 -s base -b 'dc=suretecsystems,dc=com' contextCSN
If they are the same, then replication has finished, otherwise replication has not finished or has failed.
For more technical detail, please see http://www.openldap.org/doc/admin24/replication.html#LDAP[?]%20Sync%20Replication
The first official release is out,
and you can see lots of new features
. Unfortunately there are still a few Realtime LDAP[?] driver bugs
, but it's getting there.
It's well worth having a play with Asterisk 1.6.0 though.
There's an interesting interview video
with Gerald Carter
and Likewise Software
talking about Likewise Open
Likewise Open is an open source, community project sponsored by Likewise Software to integrate Linux, Unix, and Mac in Microsoft Active Directory and authenticate users with their domain credentials. Likewise Open is licensed under the open source licensing so you can download it for free. Or, if you would like to become involved with the project, join one of the community mailing lists and discuss Likewise Open with other users and developers.
use Likewise Open
for some of its cusomters and it's very good if you need to go down that route....
Just a quick one to say our partners Symas
have written a very nice peice about how to pick your base hardware and operating system for use with OpenLDAP in your Enterprise
Read the full article
The key to this first factor is that OpenLDAP is the most efficient, most stable, and most suitable LDAP[?] Directory Service technology for Enterprise production use. Installing it as a new service or an upgrade to an older technology will be the most cost-effective step assuming the capacity is available. In general, replacing an older Directory Technology will reduce the processor load by two to five times. It will also improve the stability of the server(s) making simplification of configurations tuned to frequent server outages possible. Symas OpenLDAP is available under inexpensive annual support subscriptions with no consideration for the number of CPUs in the server or the number of objects/entries in the Directory, too. So, our preference of platform, in general, is put OpenLDAP (Symas OpenLDAP) on what you’ve got!
W. Michael Petullo
has published a very detailed article for Red Hat Magazine
about using the Asterisk
Driver and Fedora Directory Server
It's well written and a good read, but just so you know, OpenLDAP can easily be used and should have been the first choice as I'm sure our partners in crime Symas
would point out too
But hey, it's a Red Hat
Magazine so you can't blame them really...
Voice over Internet Protocol (VoIP) has emerged as a popular technology for modern voice communications. Many organizations have replaced their analog or proprietary digital telephone systems with VoIP-based solutions. This allows the consolidation of telephone services into an existing IP infrastructure. In addition, using IP to host voice services lets the organization leverage existing expertise–while retaining all of the network’s management advantages. Though not without its disadvantages, VoIP provides a compelling option to those looking for a telephone solution.
This article will present a simple VoIP solution using Asterisk, an open source private branch exchange (PBX) product. It will show you how to install Asterisk, configure it using its LDAP backend, and connect to it using the Ekiga software VoIP client and a Cisco 7900 Series VoIP telephone to make calls.
The first comment about the article is right though:
In general experienced users from the Asterisk community advise against purchasing Cisco phones for business deployment with Asterisk and recommend Polycom, Aastra or Snom instead. Cisco phones are very expensive, difficult to setup, technical documentation is not easily accessible for the end-user, their SIP firmware has some nasty surprises and as far as I know that cheap SmartNet contract is still quite difficult to get.
The LDIF Schema
and normal LDAP schema
are available in non-FDS
format and are contributed to the Asterisk Project by Suretec

Flexi Time Manager "in the pink" after shortlisting for National Business Award
Entrepreneur Louise Wreathall has been shortlisted for the ‘Best Mumpreneur’ award at the National mother@work awards 2008. Louise, creator of Flexi Time Manager, which offers an online flexi time recording service, launched her business last year and has seen it go from strength to strength. She will attend a reception at 11 Downing Street on 18th June, where the winners will be announced.
Louise says, “Being shortlisted for this award means so much to me. Of course I’d be thrilled to win, but reaching the final stage itself shows that my work in getting the business where it is today has paid off.”
As a working mother who returned to work after a career break, Louise knows how important flexi time can be. Working in the HR department of a charitable organisation, she was responsible for administering a time consuming flexi time system for 30 staff, using scraps of paper and mental arithmetic to calculate hours worked. When staff numbers doubled, she knew something had to change, and set about creating an electronic timesheet system. By 2005, Louise had set up the business and set about trialling her own online time management system. With the help of Enterprise North East Trust, and local networks Women Into Business and Aberdeen Entrepreneurs, she learned the fundamentals of business management, finally launching the fully tested web application in November 2007.

I really enjoyed the conference
, my first time speaking
at one, bit nervous, but it can only get better

Quite a few interesting articles and blog posts today.
Whenever I see a few good ones, I'll do one of these roundup posts.
