While adding an additional vCenter Server to our Multi-Site Single Sign On instance I encountered a problem as I entered the details of the existing SSO.
The error thrown was:
User credentials are incorrect or empty. Provide correct credentials.
After a couple of hours online with VMware support I took a guess at the problem. On the existing Single Sign On Configuration I have added the Active Directory domain DefinIT and in order to enable integrated authentication from the vSphere Client I moved it to the top of the list - this meant that System-Domain is no longer the default authentication domain. The SSO admin account (admin@System-Domain) is a part of that domain and so my guess is that the installer tries to authenticate using [email protected] rather than System-Domain, which of course failed.
Moving System-Domain back to the top of the list allowed me to install correctly, and once finished I could drop it back down to allow integrated authentication again.
I've been learning my vSphere 5 config maximums before my upcoming VCP5 exam, so in a supreme effort of procrastination I thought I'd write a PowerShell quiz script: here it is!
Save the QuizMe.ps1 file into a folder and then place one or more text file in the same folder containing a comma delimited set of questions and answers. Then run QuizMe.ps1!
The process of requesting certificates for vSphere 5.1 is a fairly grim, manual process. It's repetitive and easy to make a mistake on any step of the way. Since I've got to do this for quite a few VirtualCenter Servers, I thought I'd script the certificate generation if nothing else. I am following the excellent documentation provided in Implementing CA signed SSL certificates with vSphere 5.1 and more specifically in Creating certificate requests and certificates for vCenter Server 5.1 components.
The script assumes that:
- You have a working Certificate Authority
- You are in an Active Directory domain environment
- You have the relevant permissions to modify Certificate Templates, Request and Issue certificates.
- You have installed OpenSSL v1.0.1c or later.
You will need to modify the configuration section to suit your environment and the $WorkingDir folder should exist before you run the script.
