> This user configured using the gateway.ldap.bind.user configuration is used
> to bind against the LDAP Proxy. The gateway server currently creates a user
> in the local LDAP using this configuration and the aliased password. The
> downside of this approach is that there is currently no tracking for this
> user and no way to automatically remove this user if the config changes nor
> rotate the password. This user is also returned in search queries against the
> LDAP Proxy.
> I propose creating a new authentication interceptor to manage this user
> in-memory. This way the user won't be persisted and will automatically be
> unable to authenticate if the configuration changes.
