It’s a very strange mistake.
We have a Spark 2.8.3 client and an Openfire 4.4.1 server in connection with Kerberos.
Our Spark customers log in with SSO for “normal users” without problems, but in case the user has local administrator privileges in the machine, Spark startup fails.
The solution is to mark Spark.exe as “Run this program as administrator…” if you want a successful startup.
Any idea why this might happen? Thank you
