I am building a web application with the Play Framework. To authenticate the users of my application I use LDAP. I am new to the play framework and async programming. I wanted the LDAP authentication to be async and do not block my app. So I created a Promise and put the LDAP authentication code in it. My code is working but I am not sure if it is Async or not. How can I verify that it is really Async. Here is my code
public class ActiveDirectoryServices {
public static final String ldapURL = Play.application().configuration().getString("ActiveDirectory.url");
public static final String domainName = Play.application().configuration().getString("ActoveDirectory.DomainName");
public static final int timeout = Play.application().configuration().getInt("ActoveDirectory.timeout");
private static final String account = "account";
private static final String pass = "password";
public static Promise<Boolean> authenticate(String username, String password) throws AuthenticationException, CommunicationException, NamingException{
Hashtable<String, String> env = new Hashtable<String,String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put("com.sun.jndi.ldap.connect.timeout", ""+(timeout*1000));
env.put(Context.PROVIDER_URL, ldapURL);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username+domainName);
env.put(Context.SECURITY_CREDENTIALS, password);
DirContext authContext = null;
authContext = new InitialDirContext(env);
return Promise.pure(Boolean.TRUE);
}
}
Then in a controller I use the above code as following:
try {
Promise<Boolean> promiseActiveDirectoryCheck = ActiveDirectoryServices.authenticate(userName, password);
return promiseActiveDirectoryCheck.flatMap(response -> {
if(response){
return Promise.pure(ok("access granted"));
}
});
}catch (AuthenticationException exp) {
return Promise.pure(ok("access denied"));
}catch (CommunicationException exp) {
return Promise.pure(ok("The active directory server is not reachable"));
}catch (NamingException exp) {
return Promise.pure(ok("active directory domain name does not exist"));
}
