Force ADFS Database Sync
This’ll be a quick one – I ran into an issue last night where my secondary ADFS servers were not updating their database settings from the primary, and hadn’t updated in over 10 days. This was causing problems, as I had made some changes to ADFS to configure Yammer SSO, and the correct claims rules weren’t being applied if users hit the wrong server.
I checked the Poll Duration in PowerShell, and found that it was set to the standard 300 seconds (5 minutes), and not some insanely long interval:
I tried changing to a shorter poll interval by using the following command:
Set-AdfsSyncProperties -PollDuration 10
This drops the poll duration down to 10 seconds, so you’d think that it would update pretty quickly. Sadly, if a server is already not syncing at 5 minute intervals, setting a shorter sync still doesn’t change anything.
After looking around the web, I couldn’t find any options to force a database sync either through PowerShell, or through the GUI. Thankfully, the resolution to the problem is actually quite simple – just restart the ADFS services, and this will force the database to resync immediately.
Since I was already in PowerShell, I restarted the service using the following command:
You can, of course, just restart the service through services.msc – but I like using PowerShell whenever I can, so there you go!
