One thing to verify that time between the CUCM and IdP (Microsoft ADFS server) is in sync. You can download the logs from CUCM using RTMT and analyse if there is any issues in the time.  In order to do that, you can set the SSO trace to debug on your CUCM Publisher. To do this, following the below steps:

Reproducing the Error 

  1.  Launch Internet Explorer and enter CUCM FQDN and login via SSO
  2. Notice the time when you encounter the error

Setting up SAML Trace to Debug

  1.  Login to CUCM Publisher
  2. Enter the command “set samltrace level debug”

Collecting logs from RTMT

  1.  Launch RTMT and enter the Call Manager IP Address and credentials.
  2. Navigate to Trace & Log Central.
  3. Click on Collect Files.
  4. Click on Next (Do not select any option).uccollabing.com
  5. Checkbox “Cisco SSO” on your Call Manager Publisher.
  6. Click on Nextuccollabing.com

  6.  As we see that there was delay as per the logs, now let’s try to fix the issue by making some changes in AD FS server.

Modifying the SKEW value in AD FS Server

  1. Login to AD FS Server and open power shell.
  2. Enter the following command.
    Get-AdfsRelyingPartyTrust -Identifier CUCM-Pub-FQDN | select *identifier*, *skew*

    NOTE: Modify CUCM-PUB-FQDN with the FQDN of your Call Manager

    uccollabing.com

  3. If you notice that  “NotBeforeSkew” is set to 0 minute. Let’s modify this value to 1 minute.
  4. Enter the following command
    Set-AdfsRelyingPartyTrust -TargetIdentifier "CUCM-Pub-FQDN" -NotBeforeSkew 1

    uccollabing.com

  5.  If you notice that  “NotBeforeSkew” is set to 1 minute
  6. Now try accessing the CUCM Publisher via SSO and your issue should be resolved.
