Integrated Windows Authentication stops working with SAS web applications if you apply Hot Fix M3B001 to a system. 

Symptoms

If Hot Fix M3B001 is applied, the message, "The system is experiencing problems, please contact your administrator", occurs on the SASLogon screen when you attempt to access SAS web applications using IWA. In the SASServer1_1 server.log that is located at SAS-configuration-directory/Lev1/Web/WebAppServer/SASServer1_1/logs, an error similar to the following is shown:

Cause

This error is caused by a change in the GenericPrincipal class that occurred between Tomcat versions 9.0.55 and 9.0.75. Because Hot Fix M3B001 upgrades the version of Tomcat from 9.0.55 to 9.0.75 on SAS^® 9.4M7 (TS1M7) systems, this change now causes an issue for IWA which uses these classes. 

Workaround

There is no workaround for this issue.

If IWA is configured and you applied Hot Fix M3B001, you must do one of the following in order to use web applications:

• Restore your system to before M3B001 was applied.
• Undo the configuration for IWA.

If you apply Hot Fix M3B001 to a SAS® 9.4M7 system with IWA configured for the SAS web applications, IWA will not work due to a change in Tomcat 9.0.75 for the GenericPrincipal class. The browser displays this message, "The system is experiencing problems, please contact your administrator."
