Setup OpenLDAP on MAC

By Sagar Chaudhari

macOS (Mac OS X or OS X) is the current series of Unix-based graphical operating systems developed and marketed by Apple Inc. designed to run on Apple's Macintosh computers ("Macs"). Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS after Microsoft Windows. Recently, while working on one of my projects, there was a requiremnt to integrate our system with LDAP i.e. Lightweight Directory Access Protocol (LDAP). So, I wanted to try out some samples by installing OpenLDAP on my MAC. Initially, it looked streightforward but later I realized that there are multiple steps involved to get OpenLDAP up and running in my Mac. So, I thought of documenting various steps so that others can refer them.

What do you need to begin?

  • MAC
    • Obviously you need MAC because these steps will work only for MAC (Sorry Windows users)
  • Homebrew
    • This is a package manager for macOS. Click here and follow the instruction to install this on your MAC.
  • OpenLDAP
    • Click here and download the .tgz file. At the time of this blog, the latest available version was 2.4.45
  • JXplorer
    • This is an open source LDAP browser. Click here and download osx.zip file. At the time of this blog, the latest available version was 3.3.1.2

Setup

Lets begin the step now. I am assuming that you already have Homebrew installed. Now, we need to install Berkeley Database which is needed for OpenLDAP. Open "Terminal" and execute following command to install Berkeley DB.

Output after executing the command:

Now, its time to configure OpenLDAP. Extract the contents of OpenLDAP .tgz file. Open "Terminal" and go to the openldap-<version> folder and execute following command.
Note that LDFLAGS and CPPFLAGS values are taken from the output of Berkeley DB install command.

If everything is successful, last line of above command should be: Please "make depend" to build dependencies.Next step? Yes, we will execute this command.
This will take time, but once this is done we will execute following command which will build OpenLDAP and make it ready to install.
Now, following step is optional but it is recommended. This command will execute various unit tests. Executing unit tests will take time, so be patient.
Once all the tests are complete and successful, we are now ready to install OpenLDAP. Following command will install OpenLDAP on your MAC.
Now the installation is complete. After installation two folders are generated. The first one is /usr/local/var/openldap-data where data is stored. Second one is /usr/local/etc/openldap where all the installation files will be present. Here are the steps for configuring slapd.conf file.
The slapd.conf file contains "rootpw". You can choose to keep this value in plaintext format which can be a security issue. If you choose to encrypt the value, then you will have to execute following command which generates encrypted password.
Now execute following command to launch OpenLDAP.
Now, create root-ou.ldif file with following contents.
Finally, execute following command to add root organization unit.
You can now use any LDAP browser to manage LDAP tree. I am using JXplorer.
All the best!

    successfully installed this thing.
    One moment - directory /usr/local/var/openldap-data - didn't appear - so, I had to create it manually.

How to Extract Values from Response Header in JMeter?

By Sagar Chaudhari
JMeter is a powerful tool for API testing. Let's say you are are writing test cases for one of your RESTful service; and you want to extract and validate the value returned as part of response header. It is little bit tricky to extract the value from Response Header in JMeter , but it is possible. For example, your RESTful service returns "ETag" in response header. When you look at the raw response data, the value is displayed something like this: ETag: 2666d92fa9ebf10250acdb235546f045 To exact value of this reaponse header in JMeter: Right click on your HTTP request, then add Post Processor element - Regular Expression Extractor Select Radio button - Main sample only Select Radio burron - Response Headers Type some name in Reference Name section - for example, eTagVariable Type this expression in Reference Expression section - ETag:\s+(.+) IMPORTANT: This expression will select pick the ETag response header parameter and select everything after colon bla

MuleSoft - Static IP Addresses and Multiple Workers

By Sagar Chaudhari
Did you just realize that your Mule Application requires horizontal scalling ? Well, thats easy - just go to CloudHub Runtime Manager, select your application and change the "Workers" count from 1 to either 2, 3 or 4. If numbers are grayed out, then you might have to adjust the "Worker Size", or purchase additional capacity from MuleSoft. So, what is the issue then? At the time of the blog post, based on Mule documentation, if you are using only 1 worker and if you want to apply static IP, then you can simply navigate to "Static IPs" section in Runtime Manager and allocate the static IP address. The issue is when you want to apply Static IP addresses for more than 1 workers for various reasons including IP whitelisting. Based on Mule documentation you cannot apply static IPs if you are using more than 1 worker. From Mule Documentation: "Static IPs are not supported for private IP addresses inside a CloudHub VPC and it is only supported for app

Access GitHub Repositories with SourceTree and 2FA (2 Factor Authentication)

By Sagar Chaudhari
Many developers and organizations use GitHub as code repository. Similarly, many prefer to commit code in GitHub repositories using various commands. I personally think that using any kind of user interface for committing code and performing various GIT operations is much more simpler and productive. SourceTree is one such Atlassian product. SourceTree is a free Git client and provides beautiful GUI that offers a visual representation for various Git repositories. For added security, you can enable 2FA (i.e. 2 Factor Authentication) for your GitHub account. Configuring GitHub with SourceTree is very very simple. Here are the steps on MAC OS (steps on Windows OS are similar): If you have not enabled 2FA: Open SourceTree and go to Preferences Select Accounts Click on Add button to add account On the pop-up window, select Host as "GitHub" Select Auth Type as "Basic" Type your GitHub username (not email) Type your password Select Protocol as HTTPS

MuleSoft LDAP Connector With Example

By Sagar Chaudhari
As we all know, the L ightweight D irectory A ccess Protocol ( LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. A common use of LDAP is to provide a central place to store usernames and passwords. This allows many different applications and services to connect to the LDAP server to validate users. This has a major benefit that allows a central place to update and change user passwords. With MuleSoft’s LDAP Connector , we can access and maintain directory information services over an IP network by connecting to any LDAP server. LDAP Connector is developed by MuleSoft's developer community and it is categorized as Community Connectors. Latest LDAP Connector documentation is available here . Unfortunately, the information and examples of this connector are limited and scattered all over the web. Today, I am trying to cover as many details as p
