2319010 - Reports using STS such as Analysis Workspaces or Webi fail after upgrading to BI 4.1 SP08 or newer or just about anything on 4.2

Symptom

  • Receive error like "Failed to open connection to cube [session] Initialization of destination custom_session-hostname: SSO failed: Connect to SAP gateway failed Connection parameters: TYPE=A DEST=custom_session-hostname::EN: SSO ASHOST=BWhostname SYSNR=00 SNC_MODE=1 SNC_QOP=1 SNC_MYNAME="p:SNC DN" SNC_PARTNERNAME="p:SNC partnerDN" PCS=1
  • Receive error failed to get connection [BWsystem] Connect to SAP gateway failed MSHOST=BWSERVERname:48xxport WSAETIMEDOUT: Connection times out
  • The issue may not affect all users
  • The issue may or may not also affect Web Intelligence (BICS) but the errors could be dofferent
  • The issue may or may not appear in the Information Design Tool when testing the Connection
  • The issue could also affect predefined users' secondary credentials, and SSO connections (making it difficult to determine if it's authentication-related, i.e. KBA 1767629 has been updated to remove SNC encryption if that is the case)
  • To resolve the analysis going into the CMC > Authentication > SAP > SNC configuration and disabling SNC should temporarily resolve (but this could break any legacy reporting using SNC for SSO while testing)

APS logs may show something like:
