Erro ao executar spring Security

Estou tendo o seguinte erro:
Field authenticationManager in com.ronaldo.money.api.config.AuthorizationServerConfig required a bean of type ‘org.springframework.security.authentication.AuthenticationManager’ that could not be found.

Action:

Consider defining a bean of type
’org.springframework.security.authentication.AuthenticationManager’ in your configuration

Classe:

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.security.authentication.AuthenticationManager;

import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;

import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;

import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;

import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;

import org.springframework.security.oauth2.provider.token.TokenStore;

import org.springframework.security.oauth2.provider.token.store.InMemoryTokenStore;

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

	@Autowired
	private AuthenticationManager authenticationManager;
	
	@Override
	public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
		clients.inMemory()
			.withClient("teste")
			.secret("teste")
			.scopes("read", "write")
			.authorizedGrantTypes("password")
			.accessTokenValiditySeconds(1800);
	}
	
	@Override
	public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
		endpoints
			.tokenStore(tokenStore())
			.authenticationManager(authenticationManager);
	}
	
	@Bean
	public TokenStore tokenStore() {
		return new InMemoryTokenStore();
	}
