There can be multiple reasons why authentications to the SAML applications fail.
Time Synchronization: SocialAccess depends on timestamps to function correctly. Synchronize time between the VMware host, the appliance, and the workstations. Download the authentication logs. In the catalina.out file, search for the error clock skew.
SAML Authentications: Firefox contains a SAML debug add-on that you can use to view the SAML authentication between SocialAccess and the SAML applications. Download the add-on SAML tracer to view the SAML request.
