How do I find my SSO Server 5.5 Site name?

During an SSO (Single-Sign On) Server 5.5 installation, you may have noticed a new input parameter called Site Name that you must now specify. This new Site name is meant to help users identify a specific SSO Server when more than one exists in an environment and used mainly for groupings today.

Note: Something to be aware of is that the Site Name can not be changed after installation which is a bit unfortunate, so choose carefully.

When adding an additional Windows-based SSO Server to an existing environment, a drop down list will automatically be populated with all the Site names. This is great if the Site name you selected makes sense (ideally it would) but in case you did not choose a specific name or forgot the relationship between the Site name and the SSO Server, then this can potentially post a challenge.

In my lab I have been recently doing some "SSO" testing and I needed to figure out the Site name for one a vCenter Server running on Windows as well as for a VCSA (vCenter Server Appliance). With a bit of digging and testing, here is how you can find the Site name for a given SSO Server.

Note: Since the VCSA is a pre-built Virtual Appliance, the Site name has already been configured to to always be "local".

Method 1 - You can leverage an SSO CLI utility found both in a Windows vCenter Server as well as the VCSA to query for this information.

Windows vCenter Server Utility: C:\Program Files\VMware\Infrastructure\VMware\CIS\vmware-sso\ssolscli.cmd

VCSA Utility: /usr/lib/vmware-sso/bin/vi_regtool

Both commands function exactly the same but do have different paths/name. The operation that we will be using is the "listServices" and we will also need to specify the Lookup Service URL which will be in the form of https://[SSO-SERVER]:7444/lookupservice/sdk

Here is an example of using the ssolscli.cmd in vCenter Server for Windows:

In the output you should see a list of services registered and you will also be able to find the Site name in either the serviceId property which includes the Site name in the pre-fix. In the screenshot above, the Site name is "Santa Barbara". You can also find the Site name by looking at viSite property for each service and based on the URL, you will see the IP Address/Hostname in which the Site name is associated with.

Method 2 - You can also find the Site name for a given SSO Server by logging into the vSphere Web Client and under the advanced vCenter Server settings, you can filter on config.vpxd.sso string and look for the serviceId property which will include the Site name. You can also find this same information by looking at the vCenter Server configuration file (vpxd.conf) but if you have access to the vSphere Web Client, it is a much quicker way as seen in the screenshot below.
