Configuring WSO2 API Manager to set permissions based on SAML2 attributes - wso2

I'm trying to set user privilege levels (publish, create, subscribe, etc.) in the WSO2 API Manager at logon based on custom attributes contained in the SAML2 token. Not based on a list of active users and their mapped roles. Is it possible to customize the user privileges with a dynamic set of custom attributes?
The SAML token is coming from a third party source, however integration with WSO2 Identity Server is possible if required.

API Manager runs Identity Server application management under the hood to look up user roles and permissions. In org.wso2.carbon.identity.application.mgt.ApplicationMgtUtil you can see the isUserAuthorized method that is presumably fired whenever the application needs to check the user's permissions.
/**
* #param applicationName
* #param username
* #return
* #throws IdentityApplicationManagementException
*/
public static boolean isUserAuthorized(String applicationName, String username)
throws IdentityApplicationManagementException {
String applicationRoleName = getAppRoleName(applicationName);
try {
if (log.isDebugEnabled()) {
log.debug("Checking whether user has role : " + applicationRoleName + " by retrieving role list of " +
"user : " + username);
}
String[] userRoles = CarbonContext.getThreadLocalCarbonContext().getUserRealm()
.getUserStoreManager().getRoleListOfUser(username);
for (String userRole : userRoles) {
if (applicationRoleName.equals(userRole)) {
return true;
}
}
} catch (UserStoreException e) {
throw new IdentityApplicationManagementException("Error while checking authorization for user: " +
username + " for application: " + applicationName, e);
}
return false;
}
You should be able to replace
String[] userRoles = CarbonContext.getThreadLocalCarbonContext().getUserRealm()
.getUserStoreManager().getRoleListOfUser(username);
with code that will retrieve roles based on the attributes present in the SAML2 token, though obviously you'd have to build and support a structure capable of storing such a mapping.

WSO2 Identity Server 5.7.0 - Password Policy Request for Minimum Password Age

I have researched at length all of the password policy options that have been added to the latest WSO2 Identity Server (5.7.0). While a big improvement over versions just a year old, my customer still is not satisfied over one issue. Using a password policy authenticator, looks like we can force a user to change their password every so many days, and using the now default policy options can enforce a password history requirement of any number to our liking. However, the history option could be overcome by a determined user simply changing his password the number of times required to age his password quickly in a single setting--unless there were a required "minimum password age" that would preclude them from doing so. All available options in History, Patterns, and Password Authenticator do not address this. This reference from Windows 10 security threat protection addresses the validity of this very issue: https://learn.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/minimum-password-age.
Is there a way I can set a minimum age in WSO2 IS now also? If not, should this not be included as a password policy in the history options?
This feature is not currently available in the WSO2 IS product, But we can fulfil this requirement easily using the extensions available in the core user management system.
The available password history feature has the history of the changed password dateTime, we can use those data to enforce this requirement.
Create a new Identity Connector to configure the minimum password age and Abstract Event Handler to enforce the validation during password change event.
public class PasswordMinAgeValidationHandler extends AbstractEventHandler implements IdentityConnectorConfig {
private static final Log log = LogFactory.getLog(PasswordMinAgeValidationHandler.class);
#Override
public void handleEvent(Event event) throws IdentityEventException {
// Validate the password age with min age configured
}
#Override
public String getName() {
return "passwordMinAge";
}
#Override
public String getFriendlyName() {
return "Password Minimum Age";
}
#Override
public String getCategory() {
return "Password Policies";
}
#Override
public Map<String, String> getPropertyNameMapping() {
Map<String, String> nameMapping = new HashMap<>();
nameMapping.put(PasswordMinAgeConstants.PM_MIN_AGE_ENABLE, "Enable Password Minimum Age Feature");
nameMapping.put(PasswordMinAgeConstants.PW_MIN_AGE_COUNT, "Password Minimum Age (Days)");
return nameMapping;
}
#Override
public void init(InitConfig configuration) throws IdentityRuntimeException {
super.init(configuration);
IdentityPasswordMinAgeServiceDataHolder.getInstance().getBundleContext().registerService
(IdentityConnectorConfig.class.getName(), this, null);
}
public Properties getDefaultPropertyValues(String tenantDomain) throws IdentityGovernanceException {
Map<String, String> defaultProperties = new HashMap<>();
defaultProperties.put(PasswordMinAgeConstants.PM_MIN_AGE_ENABLE, configs.getModuleProperties()
.getProperty(PasswordMinAgeConstants.PM_MIN_AGE_ENABLE));
defaultProperties.put(PasswordMinAgeConstants.PW_MIN_AGE_COUNT, configs.getModuleProperties()
.getProperty(PasswordMinAgeConstants.PM_MIN_AGE_ENABLE));
Properties properties = new Properties();
properties.putAll(defaultProperties);
return properties;
}
}
Make this class an OSGi bundle and register the PasswordMinAgeValidationHandler as AbstractEventHandler
protected void activate(ComponentContext context) {
try {
BundleContext bundleContext = context.getBundleContext();
IdentityPasswordMinAgeServiceDataHolder.getInstance().setBundleContext(bundleContext);
PasswordMinAgeValidationHandler handler = new PasswordMinAgeValidationHandler();
context.getBundleContext().registerService(AbstractEventHandler.class.getName(), handler, null);
} catch (Exception e) {
log.error("Error while activating identity governance password min age component.", e);
}
}
Deploy the jar in IS_HOME/repository/components/dropins
Add the following configurations in the IS_HOME/repository/conf/identity/identity-event.properties
module.name.13=passwordMinAge
passwordMinAge.subscription.1=PRE_UPDATE_CREDENTIAL
passwordMinAge.subscription.2=PRE_UPDATE_CREDENTIAL_BY_ADMIN
passwordMinAge.enable=false
passwordMinAge.count=5
Restart the IS server
In the Resident Identity Provider configuration -> Password Policies, enable both Password History and Password Minimum Age features.

Access API using client id and secret key in laravel/lumen

I have created an API for my web application. Now I want to give access to the world but before giving access I want mechanism something like Facebook API, Twitter API, Google API who provides client ID and Secret Key. Currently, I am using JWT AuthController, user login with his credentials and return a token, I don't want the users to be login.
I want the user can access my API using client ID and secret key? Another thing is that and How I will create client ID's and secret keys for the users?
Is this can be achieved using JWT Auth?
Any help?
I have read the article and quite promising it is, but after few post it recommends to use oauth2, here you go:
https://laracasts.com/discuss/channels/lumen/api-authorization-via-public-and-secret-keys
quotes:
Just add in the class to your API config.
namespace App\Providers\Guard;
use Dingo\Api\Auth\Provider\Authorization; use
Dingo\Api\Routing\Route; use Illuminate\Http\Request; use
Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException;
class GuardProvider extends Authorization {
/**
* Get the providers authorization method.
*
* #return string
*/
public function getAuthorizationMethod()
{
return 'X-Authorization';
}
/**
* Authenticate the request and return the authenticated user instance.

public function authenticate(Request $request, Route $route)
{
$key = $request->header(env('API_AUTH_HEADER', 'X-Authorization'));
if (empty($key)) $key = $request->input(env('API_AUTH_HEADER', 'X-Authorization'));
if (empty($key)) throw new UnauthorizedHttpException('Guard', 'The supplied API KEY is missing or an invalid authorization header was sent');
$user = app('db')->select("SELECT * FROM users WHERE users.key = ?", [$key]);
if (!$user) throw new UnauthorizedHttpException('Guard', 'The supplied API KEY is not valid');

Websphere Role Based WS-Security with UsernameToken

Through the Websphere Console I've setup a Policy Set and a Policy Set Binding in order to support UsernameToken authentication on a webservice. As expected, it is rejecting web service calls without correct usernames and passwords. However, it is now accepting every user in the connected LDAP.
I would like to be able to only allow access to users in a specific LDAP group. I have the feeling that I need to create a custom JAAS Login in the Caller settings, but I'm not completely sure.
Does anybody have a solution for this, or a direction where I should be looking?
Edit: I'm doing this to expose an IBM BPM web service.
Create your web service based on EJB not a POJO, and then use #RolesAllowed annotation to specify roles which are allowed to invoke particular method from your service. Use adminconsole, scirpt or binding file to map defined role to user or groups from the LDAP server.
This is probably much easier than fighting with Login module and more flexible.
You can create a custom JAAS login module to use when consuming the username token. You can use a JAAS config that first calls the built-in token consumer, then your custom consumer. Doing it this way means that you can use the built-in consumer to parse the token and do timestamp and nonce processing and you only have to do the username/password validation in your own login module.
The instructions can be found here: http://www14.software.ibm.com/webapp/wsbroker/redirect?version=phil&product=was-nd-dist&topic=twbs_replace_authmethod_usernametoken
(Please forgive the formatting. I'm doing the best I can with what I have available here.)
Replacing the authentication method of the UsernameToken consumer using a stacked JAAS login module
By default, the Web services security UsernameToken consumer, UNTConsumeLoginModule, always validates the username and password that are contained within the token against the WebSphere registry. You can use the SPIs that GenericSecurityTokenFactory provides to bypass this authentication method.
About this task
If you want to replace the authentication method that UNTConsumeLoginModule uses, you must provide your own custom JAAS login module to do the authentication. The custom login module is stacked under UNTConsumeLoginModule in a custom JAAS configuration. The UNTConsumeLoginModule consumes and validates the token XML. The validation of the values provided for username and password is deferred to the custom stacked login module.
Because the use of UNTConsumeLoginModule carries with it the assumption that the username and password will be authenticated, more requirements are put on a stacked login module that intends to perform this function than are put on login modules that are only intended to provide dynamic token functionality.
To indicate to UNTConsumeLoginModule that it should not authenticate the username and password, you must set the following property on the configured callback handler:
com.ibm.wsspi.wssecurity.token.UsernameToken.authDeferred=true
Like most WS-Security login modles, UNTConsumeLoginModule always puts the consumed token in the shared state map to which all login modules in the stack have access. When authDeferred=true is specified, in the commit phase, UNTConsumeLoginModule ensures that the same UsernameToken object that had originally been put on the shared state has been put in another location in the shared state. If this UsernameToken object cannot be found, a LoginException occurs. Therefore, you cannot just set authDeferred=true on the callback handler without having an accompanying login module return the token to the shared state.
Procedure
Develop a JAAS login module to do the authentication and make it available to your application code. This new login module stacks under the com.ibm.ws.wssecurity.wssapi.token.impl.UNTConsumeLoginModule.
This login module must:
Use the following method to get the UsernameToken that UNTConsumeLoginModule consumes.
UsernameToken unt = UsernameToken)factory.getConsumerTokenFromSharedState(sharedState,UsernameToken.ValueType);
In this code example, factory is an instance of com.ibm.websphere.wssecurity.wssapi.token.GenericSecurityTokenFactory.
Check the username and password in the manner that you choose.
You can call unt.getUsername() and unt.getPassword() to get the username and password.
Your login module should throw a LoginException if there is an authentication error.
Put the UsernameToken, that was obtained in the previous substep, back on the shared state.
Use the following method to put the UsernameToken back on the shared state.
factory.putAuthenticatedTokenToSharedState(sharedState, unt);
Following is an example login module:
package test.tokens;
import com.ibm.websphere.wssecurity.wssapi.token.GenericSecurityTokenFactory;
import com.ibm.websphere.wssecurity.wssapi.WSSUtilFactory;
import java.util.HashMap;

//String pw = yourCodeToLookUpPasswordForUsername(username);
//boolean match = utilFactory.verifyDigestedPassword(unt, pw.toCharArray());
//if (!match) throw new LoginException("Digested passwords do not match");
//Example:
try {
simpleUserGroupCheck(username, password, "cn=group1,o=ibm,c=us");
} catch (Exception e) {
LoginException le = new LoginException(e.getMessage());
le.initCause(e);
throw le;
}
//Put the authenticated token to the shared state
factory.putAuthenticatedTokenToSharedState(this._sharedState, unt);
return true;
}
private boolean simpleUserGroupCheck(String username, char [] password, String group) throws Exception {
String allowedGroup = null;
//get the default user registry
UserRegistry user_reg = RegistryHelper.getUserRegistry(null);
//authenticate the user against the user registry
user_reg.checkPassword(username, new String(password));
//get the list of groups that the user belongs to
java.util.List<String> groupList = user_reg.getGroupsForUser(username);
//you can either use a hard-coded group
allowedGroup = group;
//or get the value from your own custom property on the callback handler
//WSSUtilFactory util = WSSUtilFactory.getInstance();
//Map map = util.getCallbackHandlerProperties(this._handler);
//allowedGroup = (String) map.get("MY_ALLOWED_GROUP_1");
//check if the user belongs to an allowed group
if (!groupList.contains(allowedGroup)) {
throw new LoginException("user ["+username+"] is not in allowed group ["+allowedGroup+"]");
}
return true;

//implement the rest of the methods required by the

How to create Gmail Delegation with Service Account?

We use to create email delegates through Google Email Settings API, but after the deprecation of OAuth 1.0 we were no longer able to authenticate properly. After doing some research I think we should create a service account, delegate domain-wide access for that service account, then authenticate using it. However I can't seem to get it to work, all I receive from Google is 401 unauthorized. Does someone know what I am doing wrong? Here is most of the code, I'm using .Net/c# and I'm using Google Apps for business.
ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer("serviceAccountEmail")
{
Scopes = new[] { "https://apps-apis.google.com/a/feeds/emailsettings/2.0/ " },
User = "admin email string"
}.FromCertificate({X509 certificate from service account p12 file}));
credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Wait(-1);
GoogleMailSettingsService service = new GoogleMailSettingsService("domain name", "appname");
service.SetAuthenticationToken(credential.Token.AccessToken);
service.CreateDelegate("delegator", "delegate");
For those who may need this answer in the future, I was able to provide a solution through the following. For reference I am running a web app using MVC framework, but the solution could be tweaked for a console or GUI standalone app as well.
Basically, I was able to authenticate the GoogleMailSettingsService.Service.RequestFactory with a GOAuth2RequestFactory object.
For instance:
GoogleMailSettingsService service = new GoogleMailSettingsService("domain", "applicationName");
service.RequestFactory = new GOAuth2RequestFactory("service", "AppName", new OAuth2Parameters() { AccessToken = AuthorizationCodeWebApp.AuthResult.Credential.Token.AccessToken });
Now for the AuthorizationCodeWebApp.AuthResult I implemented the following:
public async Task<ActionResult> DelegationMenu(CancellationToken cancellationToken)
{
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetadata()).AuthorizeAsync(cancellationToken);
if (result.Credential == null)
return new RedirectResult(result.RedirectUri); //Will redirect to login page for Google Admin to authenticate.
Session["AuthResult"] = result;
return View();
}
public class AppFlowMetadata : FlowMetadata
{
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "ClientId",
ClientSecret = "ClientSecret"
},
Scopes = new[] { "https://apps-apis.google.com/a/feeds/emailsettings/2.0/" },
DataStore = new FileDataStore("C:\\OAuth2.0Tokens")
});
public override string GetUserId(Controller controller)
{
var user = controller.Session["user"];
if (user == null)
{
user = Guid.NewGuid();
controller.Session["user"] = user;
}
return user.ToString();
}
public override IAuthorizationCodeFlow Flow
{
get { return flow; }
}
}
A service account isn't required for this action. The Email Settings API, within the Admin SDK, allows a Super Admin to set a delegation for an account within the domain without the need to impersonate the user via a service account.
Check out this section of the Developers site for more information on this API. You can also test this on the OAuth Playground and add delegates right from there.

Unable to authenticate in accessing Dynamic CRM Online Web Service

I need to utilize Dynamic CRM Data Service Endpoint exposed to get data from one of the methods.
Service(microsoft) account has access to this service.
I've tried authenticating to Discovery Service and Organization Service using sample code provided here [https://msdn.microsoft.com/en-us/library/hh675404.aspx] and succeed. However am not able to use same authentication to access data Service as I could find anyway to relate Data Service with the other two. Doing basic authentication using Network Credentials does not work.
I have downloaded the CSDL exposed and added that as service reference to my project, which created an class of web service which extends from DataServiceContext. Am trying to retrieve data of one of the methods using LinQ queries. It returs following error:
"The response payload is a not a valid response payload. Please make sure that the top level element is a valid Atom or JSON element or belongs to 'http://schemas.microsoft.com/ado/2007/08/dataservices' namespace." On capturing using fiddle I realized that on hitting data service URL it is redirected to sign in page 'login.microsoftonline.com/'
Can anybody suggest a way to authenticate the user to access Data Serivce?
Adding code:
//<snippetAuthenticateWithNoHelp1>
IServiceManagement<IDiscoveryService> serviceManagement =

{
// Obtain organization information from the Discovery service.
if (discoveryProxy != null)
{
// Obtain information about the organizations that the system user belongs to.
