Unable To Access WAP AD FS Proxy Instance Externally

Posted on by Rhoderick Milne [MSFT]

When deploying AD FS and Web Application Proxy it is common to run into some networking issues.  Normally this is due to firewall rules not being set correctly.

However we need to be aware of the default behaviour of WAP and factor that into our deployment.

Posted on by Rhoderick Milne [MSFT]

As part of troubleshooting a recent Windows Server 2016 AD FS issue, I wanted to take a look at the database using SQL Server Management Studio (SSMS).  In order to successfully connect there are a couple of gotchas to note as the database used was the Windows Internal Database (WID).  This is the default AD FS 2012 R2 and 2016 deployments.  There is no SQL management interface and the correct con… Read the rest “Connect to AD FS 2016 WID Using SQL Server Management Studio”

Posted on by Rhoderick Milne [MSFT]

Since many certificate operations involve knowing the certificate’s thumbprint, it is always useful to to have an easy way to get this information.  In some of the online documentation it mentions you can copy the thumbprint out of the Certificate MMC snap-in and then manually delete the spaces between the data.  No thanks.

Renewing AD FS Certificates – Updated Guidance

Posted on by Rhoderick Milne [MSFT]

TLS certificates come and go.  By their nature they have a set life span and then they must be renewed.  While this is nothing new, I’ve being doing this since the 1990s, the process may become a little more frequent for some customers as the industry is eliminating three year certificates see 3-Year Certificates to Be Eliminated in Industry-Wide Change for example.

How to Enable IdpInitiatedSignon Page In AD FS 2016

Posted on by Rhoderick Milne [MSFT]

One of the deployment validation and testing tools which was also present in earlier AD FS releases is the /IdpInitiatedSignon.htm page.  This page is available by default in the AD FS 2012 R2 and earlier versions.  Though it should be noted this page is disabled by default in AD FS 2016.

PSRemoting for Office 365 AD FS Configuration

Posted on by Rhoderick Milne [MSFT]

When configuring AD FS for Office 365, one of the final steps is to link Azure AD with the on-premises AD FS deployment.  This should occur only after AD FS and WAP servers have been fully deployed, verified and tested.

When linking the AD FS infrastructure with Office 365, we must use the Azure AD PowerShell module.  We need to point the module at the primary AD FS server using the Set-MsolADFSCon… Read the rest “PSRemoting for Office 365 AD FS Configuration”
