Enterprise Single Sign-On 8.0.6

An internal certificate expiry prevents certain versions of Enterprise Single Sign-On ssoengine.exe executable from properly starting the SSOWatch service, rendering the software non-functioning.

How does this affect Enterprise Single Sign-On?

Windows applications such as Enterprise Single Sign-On utilize digitally signed certificates so that they can interact with Windows Operating Systems in a safe and secure manner. On Feb 23rd 2015 the certificate utilized by Enterprise Single Sign-On expired. This will cause the Windows Operating System to reject execution of the ssoengine.exe executable as part of the User Account Control mechanism enabled within the operating system by default. This prevents the Enterprise Single Sign-ON SSOWatch service from starting.

Customers running all Enterprise Single Sign-On 8.0.6 versions (Applies to 8.0.6 (4832), 8.0.6 SP2 (4927-2), 8.0.6 SP3 (5086), 8.0.6 SP4 (5184.6), 8.0.6 SP5 (5386)) attempting to start the ssoengine.exe service after Feb 23rd 2015 will be presented with an error dialog box stating “ssoengine.exe A referral was returned from the server”. The result is that the service does not start, rendering the Enterprise Single Sign-On unavailable. Customers using all versions of 8.0.5 and below are not impacted by this issue.
