As stated earlier, if you intend to connect to Solr, it is always recommended to use password authentication. This section will guide you with the steps to use password authentication so as to add a security layer between your application and Solr for both single user environment and multiuser environment.
When the JMX agent for remote monitoring is enabled, it uses password authentication. Depending on whether you are a single user, or multiuser, determines the way you set it up.
Tip
It is not advisable to use your regular username and password for monitoring as passwords are stored in clear text in the password file. Instead, use the usernames specified in the password file such as monitorRole and controlRole. For futher reading, refer:
