VMware vCenter 5.1 - Preappend domain name

After upgrading from vCenter 5.0 to 5.1 (and installing the new Single-sign On service), you may have noticed that you now have to use the DOMAIN\Username format when logging into your vCenter instance. Personally, I find this very agrevating; luckily, there is an easy way to have vCenter just figure out what domain you are on.

In order to get this job done, this guide assumes you have the vCenter Web Client installed (I don't believe this can be done from the vSphere Client for Windows -- if there is a way, please leave a comment below with the instructions, so I can add them here).

  1. Navigate to your vCenter Web Client
  2. Login using your admin@System-Domain account
  3. On the left side, click on Administration
  4. Underneath Sign-On and Discovery, click on Configuration
  5. Click on the Add Identity button underneath the identity sources tab (it looks like a green + sign).
  6. Enter in your domain info if it isn't already there, test the connection, and click OK.
  7. Select your domain from the Identity Sources list and click on the Add to default domains button (Looks like a globe with an arrow on it)
  8. Click the Save button in the Default Domains list below the Identity Sources list.

That should do it.  Try logging in without the domain appended and it should be good to go 🙂
