The following members return ISecurityUserLoginInfo objects:

• ISecurityUserWithLoginInfo.CreateUserLoginInfo(String, String)

Remarks

XAF has a built-in PermissionPolicyUser type for XPO and EF Core-based applications. Use it when an application employs only standard authentication or Windows Active Directory authentication.

When a user has multiple ways to log in, you need to store information for all authentication types and associate this information with the user. To do this, use the ISecurityUserWithLoginInfo (a descendant of ISecurityUser and IOAuthSecurityUser) and ISecurityUserLoginInfo interfaces.

The Project Wizard generates classes that implement these interfaces automatically for projects created with v21.1 and later.

The following example shows how to use the ISecurityUserLoginInfo interface to store a user’s authentication methods:

C# (EF Core)

using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using DevExpress.ExpressApp.ConditionalAppearance;
using DevExpress.ExpressApp.Security;
using DevExpress.Persistent.BaseImpl.EF;

[Table("PermissionPolicyUserLoginInfo")]
public class ApplicationUserLoginInfo : BaseObject, ISecurityUserLoginInfo {

    [Appearance("PasswordProvider", Enabled = false, Criteria = "!(IsNewObject(this)) and LoginProviderName == '" + SecurityDefaults.PasswordAuthentication + "'", Context = "DetailView")]
    public virtual string LoginProviderName { get; set; }

    [Appearance("PasswordProviderUserKey", Enabled = false, Criteria = "!(IsNewObject(this)) and LoginProviderName == '" + SecurityDefaults.PasswordAuthentication + "'", Context = "DetailView")]
    public virtual string ProviderUserKey { get; set; }

    [Browsable(false)]
    public virtual Guid UserForeignKey { get; set; }

    [Required]
    [ForeignKey(nameof(UserForeignKey))]
    public virtual ApplicationUser User { get; set; }

    object ISecurityUserLoginInfo.User => User;
}
