How to change the username format from employeeNumber@domain TO first name-last name in SPLUNK OKTA SAML?

[neeravmathur]

Hi Guys,

We recently setup Splunk to use OKTA SAML as SSO authentication . 
But upon configuring, the username format for users in Splunk was employeeNumber@domain which is incorrect. We need to update the username format as first name-last name.

We got in touch with the OKTA team and they updated the same at their end and sent me new updated metadata file, which I uploaded to Splunk but still username format is same and incorrect.

Can you guys help in figuring out what settings do I need to change in Splunk to make this work? I am not too good with this so try to be a bit detailed in your answers.

Thanks,
