Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Applicability

Splunk Cloud

Description

OAuth 2.1 functionality is available by default in Splunk Cloud versions 10.5.2506.3 and later. Prior to the release of this version, it was possible to manually request that OAuth 2.1 be enabled on a stack, but now it is no longer allowed. Stacks running earlier versions need to be upgraded to 10.5.2506.3+ in order to access this feature.


Investigation

Verify the current version of the Splunk Cloud instance by navigating to Settings > About. Ensure the version is 10.5.2506.3 or higher.


Resolution

1. Verify the current Splunk Cloud version.
2. If the version is below 10.5.2506.3, request an upgrade through the standard support process to reach at least version 10.5.2506.3.
3. Once the instance is running 10.5.2506.3 or higher, navigate to Settings > Authentication Methods.
4. Configure the required OAuth settings under the available menu options.
