Nagios Authentication and Importing Users with AD and LDAP

This article will guide you on how to integrate #Nagios Log Server with Active Directory or #LDAP to allow user authentication and validation with the Nagios Log Server interface.

2. Enter the proper base for the Active Directory in the "Base DN" attribute.
3. Set the Search Scope.
