I need to implement the role retrieval method in identity. Currently I do GetRoleAsync (id) and I pull out all user roles.
But when I remove a role from the user, I don't want to delete it, but deactivate it.
So I would like to tell GetRoleAsync (id) to pull out all roles with ENABLED = true
How can I do?
I suggest you can use build-in RemoveFromRoleAsync method to remove role reference with current user:
//get current user
var userId = User.FindFirstValue(ClaimTypes.NameIdentifier);
var user = await _userManager.FindByIdAsync(userId);
//remove role from current user
await _userManager.RemoveFromRoleAsync(user, "TheRoleName");

While developing a multi-tenant app with ASP.NET Core I noticed that it brings 2 new indices: NormalizedUserName & NormalizedEmail.
The main problem is that it gets too difficult to have a unique user per tenant.
What I mean is having multiple users with the same UserName & Email but different TenantID.
In order to achieve this I have to remove those indices
public static void RemoveIndexes(this ModelBuilder modelBuilder)
{
modelBuilder.Entity<ApplicationUser>(entity =>
{
var normalizedUserNameIndex = entity.HasIndex(u => new { u.NormalizedUserName }).Metadata;
entity.Metadata.RemoveIndex(normalizedUserNameIndex.Properties);
var normalizedEmailIndex = entity.HasIndex(u => new { u.NormalizedEmail }).Metadata;
entity.Metadata.RemoveIndex(normalizedEmailIndex.Properties);
});
}
My questions are:
What is the purpose of these 2 new indices?
What would it affect if we just remove them?
Is there anything we need to pay close attention to after removing them? (e.g. overriding default UserManager functionality or something to that effect)
First of all, I wouldn't change anything of the Identity Framework if I can't oversee the effects. If you insist, you can test what happens yourself. But, do you need to remove the fields?
If the relation of user-to-tenant is one-to-many, then tenantId should not be a field of ApplicationUser but rather be stored in a seperate table, like UserClaims.
You can add multiple tenantId's as claim of the same type, like http://tenant.company.com/Id. It will then become a collection of values, like what happens with roles.
If you don't want this then you can use different claimtypes, like http://tenant.company1.com/Id, http://tenant.company2.com/Id or something like that.
You can choose to include only claims that are linked to the tenant, which could be determined from the site binding or the url, for instance.
This design allows the user to login using the same password everywhere. Please note, this is about identity: who is the user? The user doesn't need to have a different password for every tenant.
It also makes it easier to change a password. Because I wonder, how does your scenario look like with multiple user records for each tenant? Will you update all records at once when a password changes? And how will you support 'forgot password' and other features?
I use usermanager.GetUserName(User) to get the username of the current user, but there is no GetUserRole for usermanager.
How can I retrieve the Roles of the user in .NET Core2.1
Any help would be appreciated.
UserManager has GetRolesAsync() method, which gets a list of role names the specified user belongs to.
var role = await _userManager.GetRolesAsync(user);
We are having a portlet on a liferay page. We want to put up up a permission on every action method that is performed. For example on page A we have landed an XYZ portlet. Now we want that whenever there is any action performed form this portlet, we want to check that if the user is having a role to perform this action or not.
It wont be a good approach to put up the code in Action method of the portlet cause we are having approximately 20 such pages and portlets.
Can we have some sort of filter or so, so that each action request is checked if the user is having the access to the content or not.
Thank you...
My idea.
Use a filter to intercept all request
You can add a filter to the Liferay Servlet to check every request.
For that you can use a hook-plugin.
Look at this :
http://www.liferay.com/fr/documentation/liferay-portal/6.1/development/-/ai/other-hooks
http://connect-sam.com/2012/06/creating-servlet-filter-hook-in-liferay-6-1-to-restrict-access-based-on-ip-location/
Issue with filter is that you can't access ThemeDisplay or use PortalUtil.getUser(request).
So you must use work around like that :
private User _getUser(HttpServletRequest request) throws Exception {
HttpSession session = request.getSession();
User user = PortalUtil.getUser(request);
if (user != null) {
return user;
}
String userIdString = (String) session.getAttribute("j_username");
String password = (String) session.getAttribute("j_password");
if ((userIdString != null) && (password != null)) {
long userId = GetterUtil.getLong(userIdString);
user = UserLocalServiceUtil.getUser(userId);
}
return user;
}
Filtering the request
To filter the request you must get :
page id (Layout id in Liferay)
portlet id
portlet lifecycle
One more time using a filter is a pain because you can get the ThemeDisplay. These params are easy to get (with real object instancee) with ThemeDisplay.
So you must get this as parameter in the request.
final String portletId = ParamUtil.get((HttpServletRequest) servletRequest, "p_p_id", "");
final String layoutId = ParamUtil.get((HttpServletRequest) servletRequest, "plid", "");
final String portletLifecycle = ParamUtil.get((HttpServletRequest) servletRequest, "p_p_lifecycle", "");
Lifecycle details :
portletLifecycle is a int and the meaning of value is :
0 : RENDER
1 : ACTION (the one that interests you)
2 : RESOURCE
I think that with this data you can be able to define if user can or cannot make the action.
You can get user roles from the user.
You can get the current page and portlet linked to the request.
And you can know if the request is an action request.
Good luck with Liferay.
You can add freely configurable permissions to Liferay, see the Developer Guide for detailed information. My first guess on this would be that these affect "model resources", e.g. the data that your portlet is dealing with, rather than portlet-resources, e.g. permissions on the individual portlet itself. Think of portlet-permissions as permissions that are defined by Liferay, model-resources as permissions where you can come up with your own vocabulary on the actions, e.g. "UPDATE_ADDRESS" etc.
These permissions will typically be tied to roles, which are granted to users/usergroups/etc.
Based on this variability, it depends on the nature of your permissions if you can write a filter to generically check permissions, or if it depends on more than the individual action call.
If you determine that there is a generic solution, look up PortletFilters, they behave just like ServletFilters. These can easily provide a home for permission checks.
It's quite hard to cover this topic in such a short answer, I hope to have given enough resources for you to continue your quest.
You can abuse some existing portlet permission like "Add to Page" and set it to roles that should call the action.
And by the rendering and action phases validate "has the user necessary permission".
Or you can create new permission and configure it by portlet-configuration. This way is cleaner, but difficulty.
My Users table (the one that I created) has the following columns:
UserId,UserName,FirstName,LastName,DOB
After I ran this command
WebSecurity.InitializeDatabaseConnection("DefaultConnection", "Users", "UserId", "UserName", autoCreateTables: true);
it created the required simple membership tables for me.
How would I go about "UnConfirming" an user or setting the "IsConfirmed" flag to false in the webpages_Membership using the new SimpleMembership API?
(Earlier, before going to simplemembership using the "Membership" class I could update an user using the api call : Membership.UpdateUser( user );)
I can't answer your question directly since I couldn't figure out a way to 'unconfirm' an account either. What I ended up doing, however, may help whoever finds this question.
I basically use Roles as a gatekeeper. Whenever I create a new account I add that user to a "User" role:
Roles.AddUserToRole(newUser.Username, "User");
I use the Authorize attribute to restrict access to my controllers (and use [AllowAnonymous] for actions that I want to be public -- like RegisterUser, for example). Then, inside each action I add a method to restrict access to only users that are in the "User" role.
if (!Roles.IsUserInRole(role))
{
throw new HttpResponseException(
new HttpResponseMessage(HttpStatusCode.Unauthorized));
}
NOTE: I'm using Web API, but if you're using MVC you should have a much easier time. Instead of manually checking if a user is in a role in each action you can just use the authorize attribute:
[Authorize(Roles = "User")]
When I want to "UnConfirm" a user I just remove them from the "User" role.
Roles.RemoveUserFromRole(user.Username, "User");
This way if a user comes crawling back I can just reactivate their account by adding them back as a User.
What I ended up doing was updating that table directly via a SQL query. Not sure if thats the recommended way of doing it, but that seemed to work for me.
(Thanks for your suggestion too).
Look at this blog post on adding email confirmation to SimpleMembership registration process, which covers how the confirmation process works. The cliff notes are that when you create a new user you set the flag that you want to use confirmation like this.
string confirmationToken =
WebSecurity.CreateUserAndAccount(model.UserName, model.Password, new { Email = model.Email }, true);
When you do this the CreateUserAndAccount method returns a unique token that you can put in an email with a link so the user can confirm that they gave you a valid email address. When they click on the link it passes the token in the URL and the controller action can then confirm the token like this.
[AllowAnonymous]
public ActionResult RegisterConfirmation(string Id)
{
if (WebSecurity.ConfirmAccount(Id))
{
return RedirectToAction("ConfirmationSuccess");
}
return RedirectToAction("ConfirmationFailure");
}
The ConfirmAccount method checks if there is an uncomfirmed token that matches in the database and if there is it sets the isConfirmed flag to true. The user will not be able to logon until this is set to true.
set requireConfirmationToken to be true: (The 4th value shown below)
WebSecurity.CreateUserAndAccount(viewModel.UserName, viewModel.Password, null, true);

I am new to LINQ to SQL and the repository pattern and was attempting to do a simple example to get an understanding of how exactly my application should be structured. On my User model object I have a method called create(). When a user is created I want to insert into my User table and insert into my user_role table to assign the user the lowest possible role. I have a method on User model called create which does all this work. Shown below. Am I on the right path with how the repository pattern with LINQ to SQL should work.
public Boolean Create()
{
UserDbDataContext context = new UserDbDataContext();
// Create user.
IUserRepository userRepo = new UserRepository(context);
userRepo.Create(this);
// Get role that user should be added to.
IRoleRepository roleRepo = new RoleRepository(context);
var role = roleRepo.GetByRoleName("rookie");
// Insert user into role.
IUserRoleRepository userRoleRepo = new UserRoleRepository(context);
User_Role userRole = new User_Role();
userRole.RoleId = role.Id;
userRole.UserId = this.Id;
userRoleRepo.Create(userRole);
context.Dispose();
return true;
}
This is my controller method.
public ActionResult Register(string username, string password, string email)
{
User user = new User();
user.Username = username;
user.Password = password;
user.Email = email;
user.DateCreated = DateTime.Now;
user.Create();
return RedirectToAction("Test");
}
Is there a better approach I could take to improve the process? Any help would be vastly appreciated.
One of the main problems in your current approach is that the repositories individually have the responsibility to create/update the entities they hold on the database - This means that if you have changes in one repository and update another repository (i.e. your Create() call) both will be committed to the DB.
The usual way to structure this is having a unit of work (i.e. see here) that sits on top of all repositories that is responsible to commit changes to the DB, this structure also allows for transactions spanning multiple repositories.
I would say you should probably keep the responsibility of the repository to be saving and retrieving data for the entity. The "role" is a bit more on the "business logic" side and I would put that one layer up in a Service so you don't do any business logic responsibilities in the repository. For example you could call it CreateNewUserService and it would take the new users from the repository and then add the role. You would call that directly from the controller passing those arguments that you are applying directly now.
That way if your business logic changes so that you want to intialize the user as something else or not at all, you don't have to rip up the repository as it can keep it's responsibility of providing the user. This keeps the separation of concerns to be more clear as well and helps with maintenance and testability of both the repository and the service.
