Thanks for helping me. I had gone through the suggested url as well. But not helping much. I am not configuring LDAP over SSL.
SSL certificate is not installed in the machine.
The issue got fixed by using the suggested url.
Thanks a lot.
May I ask how did you managed to solve your issue?
Because currently I am unable to configure tableau server with AD too,
And I passed my json file similar to yours above, and received the same output as you:
Identity store Configuration Error: External identity store was unreachable. The external store is either down or Tableau Server is unable to establish a connection.
Thank you and regards,
