Some time ago I attempted to install the first external PSC on Windows into my existing multi-site 5.5 SSO.  Despite effort i could not get it to complete successfully so gave up, used a PSC appliance, moved the rest of the environment to 6.0 and all has been well since.  I forget what the exact problem was.

Zoom forward to today, all is working.  I have 2x external PSC appliances and 2x VCSA appliances.

I attempted to upgrade to Update 1 but despite successful upgrades of PSCs and VCSAs I could not get the web client to load up after login (legacy client worked fine).  "An internal error has occurred - index 0 out of bounds'.  Web-client log files kept showing errors about not being able to contact this stale\old Windows PSC.  I was under pressure to get access to vCenter back so i rolled back to snapshots i took before starting upgrade and all is well with the world again.

Before attempting to upgrade again I would like to clear up this stale record but am having trouble.  I've been through KB2106736 but i get the following error:

    cmsso-util unregister --node-pnid Old-PSC --username administrator@vsphere.local --passwd sso_pwd

     Could not find a host id which maps to Old-PSC in Component Manager

     Failed!!!

I also try the following but get the below error:

     /usr/lib/vmware-vmdir/bin/vdcleavefed -h Old-PSC -u administrator -u sso_pwd

     fdcleavefd offline for server Old-PSC

     Leave federation cleanup failed. Error[13] - Confidentiality required.

I have run the above commands on both my PSC appliances with the same result.

Any ideas before I open a support case?

Thanks.
