I am working on an MVC4 application that has authentication completed by ADFS before the application is launched and will only be launched by successfully authenticated users. Within the application itself I have a list of users held within the following class:
public class MyAppUser : IPrincipal
{
[Key]
public int UserID { get; set; }
[StringLength(128)]
public string Username { get; set; }
public int ParticipationPoints { get; set; }
public DateTime JoinDate { get; set; }
public DateTime LastLogin { get; set; }
//1-to-1 Mappings
public int? CompanyID { get; set; }
public virtual Company Company { get; set; }
public int? ProfileID { get; set; }
public virtual Profile Profile { get; set; }
public int? SocialID { get; set; }
public virtual SocialMedia Social { get; set; }
public int? RoleID { get; set; }
public virtual Role Role { get; set; }
//1-to-many Mappings
public virtual ICollection<Block> Blocks { get; set; }
public virtual ICollection<Enrollment> Enrollments { get; set; }
public virtual ICollection<CategoryMap> CategoryMaps { get; set; }
public virtual ICollection<Feedback> Feedbacks { get; set; }
public virtual ICollection<Survey> Surveys { get; set; }
public virtual ICollection<Friend> Friends { get; set; }
public virtual ICollection<Participation> Participations { get; set; }
public virtual ICollection<Post> Posts { get; set; }
public virtual ICollection<Target> Targets { get; set; }
public virtual ICollection<CourseStatus> CourseStatuses { get; set; }
public virtual ICollection<Objective> Objectives { get; set; }
public virtual ICollection<UserCourseInfo> UserCourseInfos { get; set; }
public IIdentity Identity { get; set; }
public bool IsInRole(string role)
{
if (this.Role.Name == role)
{
return true;
}
return false;
}
}
I have created a custom role provider that is tied to my dbcontext as follows:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Configuration.Provider;
using MyApp.Data;
using MyApp.ViewModels;
namespace MyApp.Providers
{
public class MyAppProvider : System.Web.Security.SqlRoleProvider
{
private MyAppContext dbcontext = new MyAppContext(System.Configuration.ConfigurationManager.ConnectionStrings["MyAppContext"].ConnectionString);
private Repository<MyAppUser> userRepository;
private Repository<Role> roleRepository;
public MyAppProvider()
{
this.userRepository = new Repository<MyAppUser>(dbcontext);
this.roleRepository = new Repository<Role>(dbcontext);
}
public override string[] GetAllRoles()
{
IEnumerable<Role> dbRoles = roleRepository.GetAll();
int dbRolesCount = roleRepository.GetAll().Count();
string[] roles = new string[dbRolesCount];
int i = 0;
foreach(var role in dbRoles)
{
roles[i] = role.Name;
i++;
}
return roles;
}
public string[] GetAllUsers()
{
IEnumerable<MyAppUser> dbUsers = userRepository.GetAll();
int dbUsersCount = userRepository.GetAll().Count();
string[] users = new string[dbUsersCount];
int i = 0;
foreach (var user in dbUsers)
{
users[i] = user.Username;
i++;
}
return users;
}
public override bool RoleExists(string roleName)
{
string[] roles = { "Admin", "User", "BobsBusiness" };
if(roles.Contains(roleName))
return true;
else
return false;
}
public override void CreateRole(string roleName)
{
Role newRole = new Role();
newRole.Name = roleName;
roleRepository.Add(newRole);
roleRepository.SaveChanges();
}
public override void AddUsersToRoles(string[] usernames, string[] roleNames)
{
foreach (var username in usernames)
{
MyAppUser user = userRepository.Get(u => u.Username == username).FirstOrDefault();
foreach (var rolename in roleNames)
{
Role role = roleRepository.Get(r => r.Name == rolename).FirstOrDefault();
user.RoleID = role.RoleID;
userRepository.Add(user);
userRepository.SaveChanges();
}
}
}
public override string[] GetRolesForUser(string username)
{
MyAppUser user = userRepository.Get(u => u.Username == username).FirstOrDefault();
if (user == null)
{
string[] roles = new string[1];
roles[0] = "Fail";
return roles;
}
else
{
Role role = roleRepository.Get(r => r.RoleID == user.RoleID).FirstOrDefault();
if (role == null)
{
string[] roles = new string[1];
roles[0] = "Fail";
return roles;
}
else
{
string[] roles = new string[1];
roles[0] = role.Name;
return roles;
}
}
}
public override bool IsUserInRole(string userName, string roleName)
{
MyAppUser user = userRepository.Get(u => u.Username == userName).FirstOrDefault();
if (user == null)
throw new ProviderException("Username cannot be empty or null.");
Role role = roleRepository.Get(r => r.Name == roleName).FirstOrDefault();
if (role == null)
throw new ProviderException("Role name cannot be empty or null.");
if (user.RoleID == role.RoleID)
return true;
else
return false;
}
}
}
Now I have tried to create a CustomMembershipProvider but I am unsure how to tie this to the dbcontext and the MyAppUser that I have created. Due to the authentication type we do not have an AccountController and so simpleMembership is not an option. I have created the abstract class for the custom membership provider as follows:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MyApp.Data;
namespace MyApp.Providers
{
public class MyAppMembershipProvider : System.Web.Security.MembershipProvider
{
private MyAppContext dbcontext = new MyAppContext(System.Configuration.ConfigurationManager.ConnectionStrings["MyAppContext"].ConnectionString);
private Repository<MyAppUser> userRepository;
public MyAppUser User { get; private set; }
public MyAppMembershipProvider()
{
this.userRepository = new Repository<MyAppUser>(dbcontext);
User = userRepository.Get(u => u.Username == "jpmcfeely").FirstOrDefault();
}
public override string ApplicationName
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public override bool ChangePassword(string username, string oldPassword, string newPassword)
{
throw new NotImplementedException();
}
public override bool ChangePasswordQuestionAndAnswer(string username, string password, string newPasswordQuestion, string newPasswordAnswer)
{
throw new NotImplementedException();
}
public override System.Web.Security.MembershipUser CreateUser(string username, string password, string email, string passwordQuestion, string passwordAnswer, bool isApproved, object providerUserKey, out System.Web.Security.MembershipCreateStatus status)
{
throw new NotImplementedException();
}
public override bool DeleteUser(string username, bool deleteAllRelatedData)
{
throw new NotImplementedException();
}
public override bool EnablePasswordReset
{
get { throw new NotImplementedException(); }
}
public override bool EnablePasswordRetrieval
{
get { throw new NotImplementedException(); }
}
public override System.Web.Security.MembershipUserCollection FindUsersByEmail(string emailToMatch, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}
public override System.Web.Security.MembershipUserCollection FindUsersByName(string usernameToMatch, int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}
public override System.Web.Security.MembershipUserCollection GetAllUsers(int pageIndex, int pageSize, out int totalRecords)
{
throw new NotImplementedException();
}
public override int GetNumberOfUsersOnline()
{
throw new NotImplementedException();
}
public override string GetPassword(string username, string answer)
{
throw new NotImplementedException();
}
public override System.Web.Security.MembershipUser GetUser(string username, bool userIsOnline)
{
//throw new NotImplementedException();
MyAppUser user = userRepository.Get(u => u.Username == username).FirstOrDefault();
return GetUser(username, true);
}
public override System.Web.Security.MembershipUser GetUser(object providerUserKey, bool userIsOnline)
{
throw new NotImplementedException();
}
public override string GetUserNameByEmail(string email)
{
throw new NotImplementedException();
}
public override int MaxInvalidPasswordAttempts
{
get { throw new NotImplementedException(); }
}
public override int MinRequiredNonAlphanumericCharacters
{
get { throw new NotImplementedException(); }
}
public override int MinRequiredPasswordLength
{
get { throw new NotImplementedException(); }
}
public override int PasswordAttemptWindow
{
get { throw new NotImplementedException(); }
}
public override System.Web.Security.MembershipPasswordFormat PasswordFormat
{
get { throw new NotImplementedException(); }
}
public override string PasswordStrengthRegularExpression
{
get { throw new NotImplementedException(); }
}
public override bool RequiresQuestionAndAnswer
{
get { throw new NotImplementedException(); }
}
public override bool RequiresUniqueEmail
{
get { throw new NotImplementedException(); }
}
public override string ResetPassword(string username, string answer)
{
throw new NotImplementedException();
}
public override bool UnlockUser(string userName)
{
throw new NotImplementedException();
}
public override void UpdateUser(System.Web.Security.MembershipUser user)
{
throw new NotImplementedException();
}
public override bool ValidateUser(string username, string password)
{
throw new NotImplementedException();
}
}
}
I would be very grateful for any tips anyone has in connecting the MyAppUser to the custom membership provider.
