Submitting requests on behalf of other users
editSubmitting requests on behalf of other users
editThe Elasticsearch security features support a permission that enables an authenticated user to submit requests on behalf of other users. If your application already authenticates users, you can use the run as mechanism to restrict data access according to Elasticsearch permissions without having to re-authenticate each user through.
To "run as" (impersonate) another user, you must be able to retrieve the user from
the realm you use to authenticate. Both the internal native
and file
realms
support this out of the box. The LDAP realm must be configured to run in
user search mode. The Active Directory realm must be
configured with a bind_dn
and secure_bind_password
to support
run as. The PKI, Kerberos, and SAML realms do not support run as.
To submit requests on behalf of other users, you need to have the run_as
permission. For example, the following role grants permission to submit request
on behalf of jacknich
or redeniro
:
{ "run_as" : [ "jacknich", "rdeniro" ] }
To submit a request as another user, you specify the user in the
es-security-runas-user
request header. For example:
curl -H "es-security-runas-user: jacknich" -u es_admin -XGET 'http://localhost:9200/'
