Dears,

We plan to connect the ELK cluster with LDAP / Active Directory for user authentication.

What about built-in/internal accounts like logstash user? Will these accounts continue to work after establishing the connection between the ELK cluster and AD??

That's all apply to GOLD licence and ELK in version 7.7.0, three nodes cluster.

Best Regards,  
Dan
