Error in login Spark with SSO in case of user has local administrator privileges in the machine

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

Hi, I have the same problem.
there is no solution to the problems.
I advise you not to use Spark with administrative accounts.

iirc, this is more of a UAC issue. Windows is protecting the token for administators. options are a little limited. you can run as administrator, tweak uac, or create a uac exception (although I don’t recall how to do this).


Thank you very much for the response.
I have found a page where is explained how to create a uac exception:

I have tried it and works
