Class PreLoginPlugin

A plugin that is executed when the client visits the login page.

Inheritance
System.Object
Plugin
LoginPlugin
PreLoginPlugin
Inherited Members
Namespace: Softadmin.Api.Login
Assembly: Softadmin.Api.dll
Syntax
public abstract class PreLoginPlugin : LoginPlugin
Remarks

Subclass this plugin and override BeforeLogin() to for example control where the user is forwarded to after login or to immediately log in the user.

While a pre-login-plugin is able to set session variables those values are lost unless the user is immediately logged in, either by the plugin itself, single sign-on or a login link. For reliable behavior you should set session variables in a PostLoginPlugin instead unless your pre-login-plugin also assigns a logged in user.

Examples
public override void BeforeLogin()
{
	bool isGuest;
	if (this.QueryString.TryGetBool("guest", out isGuest) && isGuest)
	{
		this.UserState.Username = "GuestUser";
	}
}

Properties

SkipMultiStepVerification

Override this property and return true if this plugin is considered secure enough that no multi-step verification needs to take place after successful login. This property is only relevant when the system has multi-step verification enabled.

Declaration
public virtual bool SkipMultiStepVerification { get; }
Property Value
Type Description
System.Boolean
Remarks

Used for example when the plugin implements third-party OAuth login.

Right now the platform only has support for two-step verification by email but this property will also override any other verification method added in the future.

UserState

Gets or sets an object that controls the logged in user.

Declaration
public IUserState UserState { get; set; }
Property Value
Type Description
IUserState

Methods

BeforeLogin()

Declaration
public abstract void BeforeLogin()
Exceptions
Type Condition
System.Exception

Any exception thrown by this method will be caught and logged but will not prevent the client from logging in.
