Running the AdminUI and modifying a Partnership, enabling the signature, results in the failure to save the Partnership.
The AdminUI fails to decode the certificates dates.
Policy Server 12.8SP7 on RedHat 8;
AdminUI 12.8SP7 on RedHat 8;
Upgrade the AdminUI to 12.8SP8CR01 when this one will be available to benefit from fix DE585291, and fix DE588456 to solve this issue.
Note that the Policy Server and Policy Store definitions should be upgraded to 12.8SP8CR01 too.
