Problems Injecting Custom Authentication Manager - spring

Question

I'm attempting to use a custom authentication manager but the standard Provider manager is being called to .authenticate. I suspect it has something to do with either the AuthSever or Web Config. Any help is greatly appreciated.
AuthServer configuration:
#Configuration
#EnableAuthorizationServer
public class AuthServerConfig extends AuthorizationServerConfigurerAdapter {
#Autowired
private final DataSource dataSource;
#Autowired
public AuthServerConfig(DataSource dataSource){
this.dataSource = dataSource;
}
#Autowired
MicrosJwtConfig microsJwtConfig;
#Autowired
#Qualifier("microsProviderManager")
AuthenticationManager authenticationManager;
public BCryptPasswordEncoder encoder(){
return new BCryptPasswordEncoder(10);
}
#Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
clients.jdbc(dataSource);
}
#Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
endpoints
.tokenServices(microsJwtConfig.microsTokenServices())
.authenticationManager(authenticationManager);
}
#Override
public void configure(AuthorizationServerSecurityConfigurer security) {
security.allowFormAuthenticationForClients();
security.passwordEncoder(encoder());
security.tokenKeyAccess("permitAll()");
}
}
WebSecurity config:
#EnableWebSecurity
#Configuration
public class WebSecConfig extends WebSecurityConfigurerAdapter {
#Autowired
private ClientDetailsService clientDetailsService;
#Autowired
private MECAuthenticationProvider mecAuthenticationProvider;
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return new MicrosProviderManager(clientDetailsService, mecAuthenticationProvider );
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests().antMatchers("actuator/health").permitAll().and()
.authorizeRequests().antMatchers("oauth/token").permitAll().and()
.authorizeRequests().antMatchers("actuator/info").permitAll();
}
}
