"Free Splunk" is NOT the same as the "60-day-trial-Splunk Enterprise".
The former allows you to use Splunk in your environment, ingesting 500MB/day but leaving out many (if not all) of the features you for sure want in an enterprise environment, e.g. authentication or clustering. But still you have the main professional functionality like indexing, searching, reports, dashboards etc. with all their benefits.
The latter is the complete Splunk Enterprise solution with no reduction in functionality - but for a 60-day-trial period. In my opinion it would be unreasonable from a Splunk Inc.'s perspective to "give it away for free" 😉
Have a look to see the differences between the Splunk versions.
You can still change your trial-installation to the free version:
Just go to "Settings - LIcensing - Change License Group" and select "Free Splunk". But be aware that there's no authentication any longer. So if your Splunk installation is directly connected to the internet, everyone could analyse your data...
@chudak seems like your trial license has expired. Free License several features like Access Management is not available. Refer to Splunk Documentation: https://docs.splunk.com/Documentation/Splunk/latest/Admin/TypesofSplunklicenses
If this is for personal use you can always keep a backup of your sample/learning apps and reinstall latest version of Splunk which will give you another 60 days of trial Enterprise license.
Upgrading does not extend the trail period.
There's no "reactivation" of the trial license. Instead, as niketnilay pointed out, you could throw away your current installation (delete the whole "splunk"-directory and re-install Splunk to get another 60-day-trial. Be aware that all your collected data is thrown away also (of course 😉 )!
What do you mean with "it feels unreasonable"?
Hello. It sounds like the role your admin assigned you does not have the schedule_search capability.
I have seen Admins do that on very busy Splunk instances when resources are low.
