As the alert says, one of the certificates you are using with AD FS will expire soon. This might be either the token signing/decrypting certificates or the communication ones. Review the following article for the procedure of changing them:

http://social.technet.microsoft.com/wiki/contents/articles/2554.ad-fs-2-0-how-to-replace-the-ssl-service-communications-token-signing-and-token-decrypting-certificates.aspx

If you are using self-signed certificates for token signing/decrypting, you might want to enable auto-renewal:

http://social.technet.microsoft.com/wiki/contents/articles/1424.ad-fs-2-0-how-to-enable-and-immediately-use-autocertificaterollover.aspx

Lastly, make sure to update the trust settings once you have replaced the certificates:

It is both the Token Decrypting and the Token Signing. So how do I create new certs? I see how to replace them but I did not build this system so I do not know how to create new ones. Is this performed on a server within my network? They appear to be internal created certs since the Service Communications cert appears to be created by a third party provider.

Ok, so you are using self-signed ones. You can use PowerShell to renew them:

Add-PSSnapin Microsoft.Adfs.Powershell

Update-ADFSCertificate -CertificateType: Token-Signing -Urgent:$true 

Update-ADFSCertificate -CertificateType: Token-decrypting -Urgent:$true

Update-MSOLFederatedDomain –DomainName <your domainname>

Open in new window


This will potentially cause a downtime for all federated users, so make sure to plan it after working hours.


To avoid this from happening in the future, you might want to enable auto-renewal:

And make sure to also check the validity of the communication cert.

Oh, and of course make sure you have installed the WAAD PowerShell Module on the AD FS machine:
