I am configuring the web client to use SSO in a DMZ environment. There is an STS on the same server as well as a Forms installation. Forms is configured to use SSO and is working as expected, but I am getting an error message in the web client. When I browse to the /Laserfiche address I click on the option to sign in using Directory Server and it takes me to the STS. After entering in a username and password it redirects me back to the Web Client page. In the Web Client-> Server-> Operational log it has the error ID4037: The key needed to verify the signature could not be resolved from the following security key identifier "SecurityKeyIdentifier...'
Has anyone seen that error before or have any ideas of how to fix it? I have verified that the Web Client IIS App Pool has full rights to the certificate in question.
