We have a properly working SP2013 with ADFS environment on Amazon(EC2). We are using PING Fedrate as our SAML Token Provider. Everything was working fine till yesterday. Every user started getting following error, enter image description here

The event logs on the ADFS server shows, Event ID 364 with following details,

Encountered error during federation passive request.

Exception details: Microsoft.IdentityServer.Web.UnsupportedSamlResponseException: MSIS7029: The SAML response has content that is not supported. at Microsoft.IdentityServer.Web.FederationPassiveAuthentication.BuildSignInResponseForProtocolResponse(FederationPassiveContext federationPassiveContext) at Microsoft.IdentityServer.Web.FederationPassiveAuthentication.BuildSignInResponse(SecurityToken securityToken)

No patching was done on servers. No new known installations were done. Nothing known seems to change.

Any help would be greatly appreciated.

1 Answer 1


So, on our domain controller, the time was 10 min. ahead of the actual time. When it was corrected the users were able to enter normally.

We are assuming that the time difference was interfering with the encryption/decryption of the SAML token and hence the error says The SAML response has content that is not supported.
