Reproducing the Issue

  1. Navigate to Onboarding 1.0
  2. The following error message is displayed: Your Seamless login has failed. Please contact your system administrator.


  • User Sync Failure.
  • Wrong configuration of Authorized SP Assertion Consumer Service Settings.
  • SF_UserDefinedFields.xml may be corrupted
  • User has defined two the same locales in SuperAdmin



  • Check if the Feature "Foundation Import" is activated and configured with the correct credentials, which needs to match with the one in the jobs User and Permission Sync.

  • Check whether user sync has been properly happened and users are synced to onboarding.

  • BizX Side: In Provisioning, under "Authorized SP Assertion Consumer Service Settings", for "Assertion Consumer Service" and "Audience URL" fields, the KMS environment URL appended with the Path and the extension "/SSO/SAML20/AssertionConsumerService.aspx" should be given.

    KMS side: The same URL specified in BizX should be given in KMS Administration site, under Account Options, for the key Security.SAML20.audience.3. SF_UserDefinedFields.xml may be corrupted - this is caused by a script error.  When the file gets corrupted, a temp file is created and this file needs to be replaced with the corrupted file.

  • Delete the extra locale and the issue should be resolved.
