2.4.1.1. Remove Encryption Entirely

To reset Ambari database and LDAP passwords to a completely unencrypted state:

On the Ambari host, open /etc/ambari-server/conf/ambari.properties with a text editor and set this property
```
security.passwords.encryption.enabled=false
```
Delete /var/lib/ambari-server/keys/credentials.jceks
Delete /var/lib/ambari-server/keys/master
You must now reset the database password and, if necessary, the LDAP password. Run ambari-server setup and ambari-server setup-ldap again.
