Is there any audit trail, log file, or database table that tracks which users are connecting to SOI?
SOI 4.*
Guidance
SOI user authentication is done via EEM.
EEM maintains a audit log that is Typically located in C:\Program Files\CA\SC\EmbeddedEntitlementsManager
Log file names:
audit.log
audit.log.1
Note: if you don't know where EEM is installed check in "C:\Program Files (x86)\CA\SOI\SamUI\webapps\sam" and review the "eem-config-xml" to identify the EEM server
