after an upgrade from BI 4.2 SP2 to BI 4.2 SP7 the Crystal RAS is shown as stopped and the CrystalReports2016ProcessingServer is failed.
In the log files I can see this error for the RAS:
An uninitialized SSOSessionManager was provided!
and in the CR2016proc log there is this:
ras21-core: Single sign on initialization exception: unexpected error.
ras21-core: Single sign on will be disabled
Looking at the messages they seem to be related, has anyone got any suggestions - can't find any SAP notes or similar from googling the above.
