Adding basic security to your server, requires altering the security.json file.  For me this file was located



Add a User or Edit a Password

The set-user command allows you to add users and change their passwords. For example, the following defines two users and their passwords:

curl --user solr:SolrRocks http://localhost:8983/api/cluster/security/authentication -H 'Content-type:application/json' -d '{"set-user": {"andrew":"andrewsPass"}}'


Delete a User

The delete-user command allows you to remove a user. The user password does not need to be sent to remove a user. In the following example, we’ve asked that user IDs 'andrew' and 'harry' be removed from the system.

curl --user solr:SolrRocks http://localhost:8983/api/cluster/security/authentication -H 'Content-type:application/json' -d  '{"delete-user": ["andrew"]}'


Set a Property

Set properties for the authentication plugin. The currently supported properties for the Basic Authentication plugin are blockUnknown, realm and forwardCredentials.

curl --user solr:SolrRocks http://localhost:8983/api/cluster/security/authentication -H 'Content-type:application/json' -d  '{"set-property": {"blockUnknown":false}}'


Success response

A successful response will look like


   "responseHeader": {
