Hi @lisha7 - Welcome to our community forums!
There are some invalid settings in your configuration. For example, `type` is not a valid setting. You may want to check an example of LDAP configuration in our [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/ldap-realm.html#ldap-%20realm-configuration).
I hope that helps.

Thanks Romain.
I have given valid setting as per the documentation,
xpack.security.http.ssl.verification\_mode: certificate
xpack.security.authc.token.enabled: true
xpack.security.authc.realms:
ldap.ldap1:
order: 2
url: "ldaps://SERVER\_IP:636"
user\_search:
base\_dn: "dc=example,dc=com"
attribute: cn
group\_search:
base\_dn: "ou=groups,dc=example,dc=com"
ssl:
verification\_mode: certificate
truststore:
path: "/app/config/truststore/keystore.ks"
password: "PASSWORD"
files:
role\_mapping: "/app/config/mappings/role-mappings.yml"
unmapped\_groups\_as\_roles: false
I see below error,
java.lang.IllegalStateException: failed to load plugin class [org.elasticsearch.xpack.security.Security]
Likely root cause: java.lang.IllegalArgumentException: Incorrect realm settings found. Realm settings have been changed to include the type as part of the setting key.
For example 'xpack.security.authc.realms.file.my\_file.order'
