Does Splunk supports OAuth for REST API ?

[vallabhk]

Could you help us in confirming whether Splunk REST APIs supports OAuth authentication apart from the existing basic authentication(username/password) and authentication tokens(link). ? We see a lot of customers enquiring about it. 

Also, is it mandatory to always use an authentication token mechanism for a service account in Splunk or can we use a username/password as well ?

Splunk REST APIs don't support OAuth authentication.  But maybe this solution with a web server or LDAP will help you: https://community.splunk.com/t5/Security/Does-Splunk-support-oAuth-2-0-single-sign-on/m-p/292745/hig... 

You can use a username/password for a Service Account but you'll need to give the Service Account access to read the information you want Splunk to be able to collect/access. It only needs read rights. 

You can find examples of how to use username/password in requests here: https://docs.splunk.com/Documentation/Splunk/latest/RESTUM/RESTusing

or you can use authentification with Python script and use a session key in your requests: https://docs.splunk.com/Documentation/Splunk/8.2.4/RESTTUT/RESTsearches
