RegEx for LDAP

I have been working on a POC for injecting bulk entitlements into our Access Management System.  I guess you could think of our system as a big loop.  Entitlements are created in the AMS.  Users request an entitlement, which kicks off a workflow.  Once the entitlement is approved, it flows into AD.  The part I have been noodling around with is reading the permission out of AD.

I’ve been playing with this for years, literally.  I wrote some simple code a few years back.  For this POC, I dusted it off and showed it around.  I still had to migrate the code into the POC solution, so I had a chance to clean it up a bit.  No problem.  My old code uses UserPrincipals to pull the data out of AD.

var ctx = new PrincipalContext(ContextType.Domain);

var userPrincipal = await Task<UserPrincipal>.Factory.StartNew(() => UserPrincipal.FindByIdentity(ctx, request.UserId)) ?? new UserPrincipal(ctx);
response.User = userPrincipal.Convert();

It can be a bit slow.  At least the first query is slow.  It gets faster after the spin up.  Still…  I think I can make it better.

After poking around for a bit, I found the information I needed to access the AD container via LDAP.  Amazingly enough, the security team posted all of the needed info on the internal Wiki.  I’m not going to go into too much detail because I don’t really want to share any details about our network.

Anyway, once I pulled the data, I needed to parse the data into something I could use for my POC.  I looked around online and I could not find a single reference that showed a complete RegEx sample.  I saw some fragments, but nothing complete.  So here is what I came up with…

var regex = new Regex($@”CN=(?<CN>[\w]+)(,OU=(?<OU>\w+( \w+)*))+(,DC=(?<DC>\w+))+);

That’s it.  I only need the “CN” portion of the string but I thought I’d parse everything for future use.

Enjoy.

PS: I’ll fix the broken images when I have a chance.

Migrating from ClearDB to Azure MySQL

ClearDB is no longer included as part of my MSDN subscription.  I could either pay extra or migrate to the new Azure database for MySQL server.  I chose to migrate.   Continue reading Migrating from ClearDB to Azure MySQL

Azure Pass

Finally!!!

I got my Azure Pass approved yesterday.

The corporate firewall is so locked down that I can’t connect to any Azure SQL instance and the proxy setup won’t allow certificates to flow from a SF cluster into my browser.  Argh!

So, I had to find a work around.  Queue the begging.  😉

Updates: Cloud Development

I know it’s been a while.  This afternoon is the first in weeks that I’m had a few moments to reset my brain.

I’m neck deep in an Azure POC for my business unit.  I’m demoing a scalable, globally deployed microservice enabled system.  (I know too many buzzwords).  Think Excel client with a full cloud backend with everything that implies and it’s available worldwide.

There has been a lot to learn for this POC.  But it’s all coming together.   Along the way we did a full DevOps pipeline on VisualStudio.com.  I learned some of the ins and out for release a service fabric app to secured cluster; added more PowerShell skills to my toolbox; extended my understanding of Docker and Azure Function; etc, etc, etc.

It’s been an interesting quarter.

But why?

Updates

I’ve been developing a path to get us out of our tendency of developing separate apps to solve each business problem into a service-based solution where we get true reuse our of our components.

I was part of the problem that created our status quo.  I spent years writing custom apps for so-called one-off solutions.  I have finally learned that is the wrong way to develop apps in an enterprise environment.

So…

Complexity and The Cynefin Framework

I’ve been spending a lot of time thinking about Complexity (Theory).

Currently, I’ve got Simplexity: Why Simple Things Become Complex (and How Complex Things Can Be Made Simple) by Jeffery Kluger on my nightstand.  Complexity: A Guided Tour by Melanie Mitchell is next in the queue.  I’ve read it before, but I think I need a refresher.

I’ve got a meeting on this topic scheduled for later today.  In an effort to make things more “management friendly” I wanted to find a couple images to go along with the discussion.  In the process I stumbled across Dave Snowden’s Cynefin Framework.  He has a short video on YouTube too.   From there you can get more info.

Looks like I have more studying to do…
