I realize that this has been spoken about and that there was a solution on posted (and it did work for me on 5.4 - Now on Civi 5.6.1 any user that does not have "CiviCase: access all cases and activities" checked i get a "ERR_TOO_MANY_REDIRECTS" error when trying to access the Civicase Dashboard or Manage Cases.
I checked if the fixes were applied from the pull - And Yes they are, but I cannot have users seeing other peoples Cases - It works for the Administrator - I can access all the Cases and don't get the redirect error.
