Hello Boyan,
for what concern the Membership provider I should be ok (I can authenticate my users)
I've got really big and urgent problems (that needs to be solved asap) with the role provider.......

Here's my file :

using System;

using System.Collections.Generic;

using System.Linq;

using Telerik.Sitefinity.Security.Data;

using Telerik.Sitefinity.Model;

using Telerik.Sitefinity.Security;

using System.Configuration.Provider;

using Telerik.Sitefinity.Localization;

using Telerik.Sitefinity.Security.Model;

namespace SitefinityWebApp

public class IFRoleProvider : RoleDataProvider

private IQueryable<UserLink> ListUserLinks = null;

public IFRoleProvider()

public override Telerik.Sitefinity.Security.Model.Role CreateRole(Guid id, string roleName)

if (id == Guid.Empty)

throw new ArgumentNullException("id");

if (!String.IsNullOrEmpty(roleName))

if (this.RoleExists(roleName))

throw new ProviderException(Res.Get<ErrorMessages>().RoleAlreadyExists.Arrange(roleName));

var role = new Role();

//Telerik.Sitefinity.Security.Model.Role role = new Telerik.Sitefinity.Security.Model.Role();

//role.Id = id;

//role.Name = roleName;

//role.LastModified = DateTime.Now;

//role.ApplicationName = base.ApplicationName;

//RoleManager.GetManager().SaveChanges();

return role;

public override Telerik.Sitefinity.Security.Model.Role CreateRole(string roleName)

throw new NotImplementedException();

public override Telerik.Sitefinity.Security.Model.UserLink CreateUserLink(Guid id)

Telerik.Sitefinity.Security.Model.UserLink link = CreateUserLink();

link.UserId = id;

return link;

public override Telerik.Sitefinity.Security.Model.UserLink CreateUserLink()

Telerik.Sitefinity.Security.Model.UserLink link = new Telerik.Sitefinity.Security.Model.UserLink();

link.Id = new Guid();

link.ApplicationName = base.ApplicationName;

return link;

public override void Delete(Telerik.Sitefinity.Security.Model.UserLink item)

throw new NotImplementedException();

public override void Delete(Telerik.Sitefinity.Security.Model.Role item)

throw new NotImplementedException();

public override Telerik.Sitefinity.Security.Model.Role GetRole(Guid id)

using (IDEAEntities2 entities = new IDEAEntities2())

Telerik.Sitefinity.Security.Model.Role role = new Telerik.Sitefinity.Security.Model.Role();

var profilo = entities.SF_PROFILI.Where(a1 => a1.SFID == id).FirstOrDefault();

if (profilo != null)

role.ApplicationName = base.ApplicationName;

role.Id = profilo.SFID;

role.Name = profilo.DESCR;

// role.LastModified = DateTime.MinValue;

return role;

public override IQueryable<Telerik.Sitefinity.Security.Model.Role> GetRoles()

List<Telerik.Sitefinity.Security.Model.Role> lst = new List<Role>();

using (IDEAEntities2 entities = new IDEAEntities2())

var profili = entities.SF_PROFILI;

foreach (var p in profili)

Telerik.Sitefinity.Security.Model.Role role = new Telerik.Sitefinity.Security.Model.Role();

role.Name = p.DESCR;

Guid g = p.SFID;

role.Id = g;

//role = GetRole(p.SFID);

lst.Add(role);

return lst.AsQueryable();

public override Telerik.Sitefinity.Security.Model.UserLink GetUserLink(Guid id)

Telerik.Sitefinity.Security.Model.UserLink userLink = new Telerik.Sitefinity.Security.Model.UserLink();

using (IDEAEntities2 entities = new IDEAEntities2())

var sf_UserLink = entities.SF_PROFILI_UTENTI.Where(o1 => o1.GUID_LINK == id).FirstOrDefault();

if (sf_UserLink != null)

userLink.Id = sf_UserLink.GUID_LINK;

userLink.UserId = sf_UserLink.GUID_USER;

userLink.ApplicationName = base.ApplicationName;

userLink.Role = GetRoleFromUserLink(id);

//var mi = new ManagerInfo();

//mi.ApplicationName = base.ApplicationName;

//mi.ManagerType = typeof(UserManager).FullName;

//mi.ProviderName = "IFRole";

//userLink.MembershipManagerInfo = mi;

return userLink;

else

return null;

public override IQueryable<Telerik.Sitefinity.Security.Model.UserLink> GetUserLinks()

if (ListUserLinks != null)

//if (false)

return ListUserLinks;

else

List<Telerik.Sitefinity.Security.Model.UserLink> lst = new List<Telerik.Sitefinity.Security.Model.UserLink>();

using (IDEAEntities2 entities = new IDEAEntities2())

var linkProfili = entities.I_UTENTI.Where(o1 => o1.STATO == 0).Select(o1 => o1.SF_PROFILI_UTENTI);

foreach (var i in linkProfili)

Telerik.Sitefinity.Security.Model.UserLink userLink = GetUserLink(i.GUID_LINK);

lst.Add(userLink);

ListUserLinks = lst.AsQueryable();

return ListUserLinks;

private Telerik.Sitefinity.Security.Model.Role GetRoleFromUserLink(Guid userLinkID)

using (IDEAEntities2 entities = new IDEAEntities2())

var userlink = entities.SF_PROFILI_UTENTI.Where(o => o.GUID_LINK == userLinkID).FirstOrDefault();

if (userlink == null)

return null;

Telerik.Sitefinity.Security.Model.Role role = new Telerik.Sitefinity.Security.Model.Role();

role.ApplicationName = base.ApplicationName;

role.Id = userlink.ID_PROFILO.Value;

role.Name = userlink.SF_PROFILI.DESCR;

return role;

I can't have it working properly ... when I go to the role section in the backoffice I got a "Object not set to an instance of an object" while loading the list of users associated with the role....

can you provide me a custom role provider implementation?
Thanks
