Siteminder any release
To find if specific groups are used in user policies within Siteminder, easy way is to use the XPSExport tool with the -xb switch for full dump export where you can look into the generated xml export file and search specifically for the group names such as examplegroup1 and examplegroup2 and see if it is referenced in any of the user policies or any other objects.
Another way is to enable full policy server trace and grep on the group names to see if it being printed in the trace log files.
