Microsoft – Resources to get more familiar with Active Directory Federation Services (ADFS)

Nowadays more and more work, communication and collaboration involves multiple external parties. This can involve by example employees, customers, partners, suppliers, cloud providers/platforms/applications.

This means it is becoming increasingly important to have proper authentication and authorization methods in place for single sign on (SSO) so users can be more productive. Besides the ease-of-use It can also lead to better security.

Microsoft’s Active Directory Federation Services (ADFS) will make this possible. For more information on ADFS, here are some resources. Keep in mind though that while some information may be outdated, it will give you a broad idea of the concept and the inner workings. The current version of ADFS in Windows Server 2012 is 2.1 , while Windows Server 2008 uses 2.0

PS: Microsoft is moving more and more towards claims based authentication. Examples include Windows Server 2012 Dynamic Access Control and also SharePoint 2013 that has switched to claims based authentication by default now.

If you have some other resources that might be useful, please let me know so I can add them as well.

VMware – The VMware virtualcenter server service terminated with service specific error code 2

A friend of mine who is still a student has been building his own VMware lab environment for some time now. Yesterday he contacted me that he couldn’t get the “VMware VirtualCenter Server service” to start anymore.

The log showed: EventID 7021 “The VMware VirtualCenter Server service terminated with service-specific error 2 (0×2).”

A quick google search however showed that many things could be causing this error. Because it was a lab environment, I wanted to upgrade the virtual center to the latest version. Before doing so, I took a look at the VMware blog post covering the latest update 5.1.0B. In the readme it said:

SSO service dependency on MS SQL
When SSO is installed with local Microsoft SQL Server, the services must start in a specific order.
SSO must start after SQL Server starts. If SSO starts before SQL Server starts, restart the SSO
server after SQL server starts.”

Doing so resolved the issue. To prevent the issue from re-occurring, I made the SSO service dependent on the SQL service.

I don’t understand why this is not part of the automated installation process though 😦
