![]() ![]() To generate a new certificate, execute the following command at a PowerShell command prompt: PS C:\Update-ADFSCertificate –CertificateType token-signing. If you only see one certificate, and the NotAfter date is within 5 days, you need to generate a new certificate. If AD FS has generated a new certificate, you should see two certificates in the output: one for which the IsPrimary value is True and the NotAfter date is within 5 days, and one for which IsPrimary is False and NotAfter is about a year in the future. Look at the command output at any certificates listed. If you are using AD FS 2.0, you should run Add-Pssnapin first. PS C:>Get-ADFSCertificate –CertificateType token-signing Verify that you are logged on to the primary AD FS server.Ĭheck the current signing certificates in AD FS by opening a PowerShell command window, and running the following command: Confirm you have new token signing certificates by taking the following steps: On the other hand, if AutoCertificateRollover is set to True, but your federation metadata is not publicly accessible, first make sure that new token signing certificates have been generated by AD FS. For more information about how to renew the AD FS token signing certificates, see Certificate requirements for federated servers.įederation metadata is not publicly available If you are using a non-default configuration of AD FS (where AutoCertificateRollover is set to False), you are probably using custom certificates (not self-signed). Step 1: Ensure that AD FS has new token signing certificates In these scenarios, every time you update the token signing certificates, you must also update your Microsoft 365 domain by using the PowerShell command, Update-MsolFederatedDomain. Network security does not allow the federation metadata to be publicly available.The most common reason for this is that your organization manages AD FS certificates enrolled from an organizational certificate authority. Token signing certificates are not self-signed certificates.For example, the following scenarios might work better for manual renewal: ![]() ![]() You may choose to renew the token signing certificates manually. If you are able to verify both of these settings successfully, you do not have to do anything else.Įxample: Renew the token signing certificate manually where (your_FS_name) is replaced with the federation service host name your organization uses, such as fs. Check that your federation metadata is publicly accessible by navigating to the following URL from a computer on the public internet (off of the corporate network): The AD FS federation metadata is publicly accessible. This indicates that AD FS will automatically generate new token signing and token decryption certificates, before the old ones expire.Ģ. The AD FS property AutoCertificateRollover must be set to True.
