Why is Splunk slow when using radius authentication?

Hello

I have installed and setup RADIUS Authentication radius_auth 1.4.1, all autentiction is correct and radius user are comming up with the admin role.

The problem is that when searching a index splunk is taking a long time to fetch the data, when looking through logs I found the logs below in splunkd.log, these lines appear when running a search, alot of them. Only when using radius, not when using a local user. Seems like this is the reason for search being slow, but not sure what is going on. Can anyone help ?. Thnx

Did you set up Radius authentication on the indexers as well as the search heads?  That's not necessary and will lead to slow searches.  Only search heads need to authenticate.

Thanks for reply and sorry for late answer from me !

You reply makes sense to me, I used the radius app from LukeMurphey.net to achieve autentication via radius.

Can I ask, how to I assign the autentication on indexes and search heads with this ?

Thanks in advance

As I mentioned in my earlier reply, do not configure authentication on indexers.  If you need to sign in to an indexer, use a local account.

After installing the Radius app on your search heads, use the setup page to configure it.  The app's splunkbase page has details.
