Have you ever run into this situation where you are setting up some LDAP like Active Directory to work with Operations Orchestration and at the time you test the configuration you receive the following warning:
"The current LDAP requires privileged user credentials configured. In the current configuration, schedules might fail to run. Verify you supply correct privileged user credentials"

Well, this is for a simple reason, the privileged user you are trying to use in Operations Orchestration to does not have permission to do recursive search of objects, so every time you try to run a schedule made by an LDAP user, the privileged user needs to go through the LDAP structure, in order to find this user (object) and confirm that the said user is mapped to a role that has permission to run execute scheduled flows.
