We recently had to apply new certificates to an ADFS infrastructure. There are plenty of articles out there that detail how to do this, however we came an across and issue after the supposed successful replacement\install.
In general we followed this procedure
However what we discovered was that the ADFS proxy server would not update the Certificate. The command to do it
Set-WebApplicationProxySslCertificate
would complete successfully.
When you run the
Get-WebApplicationProxySslCertificate
we were getting back no results. It did not error, just returned nothing.
We tried a number of things to fix this, all to no avail in the end.
Ultimately we had to remove the Web Application Role from the server and then re-add it again, and then step through the configuration wizard.
During the troubleshooting we found an 383 event in the event log, not sure if that is indicative of this problem, but I include here for future reference and comment
