How to change User Identification in Splunk UBA HR... - Splunk Community

Splunk User Behavior Analytics

hello everyone
I ran into a problem with Splunk UBA that I need help with. Thank you for guiding me.
I have more than one domain in Splunk UBA and it mistakenly recognizes some users as the same user due to name similarity. 
While these users are not the same person and only have name similarities in the login ids field.

How can I solve this problem and have users with the same login ids but not have false positive anomalies?

Thank you for your guidance.
