Examples
The following example shows an event handler that passes the UserName and Password values to a custom membership provider to validate the user credentials. The event handler sets Authenticated to the return value of the ValidateUser method and sets AuthenticationIsComplete to true
so that the AuthenticationService class does not validate the credentials.
void AuthenticationService_Authenticating(object sender, System.Web.ApplicationServices.AuthenticatingEventArgs e)
{
if (e.UserName.IndexOf("@contoso.com") >= 0)
{
e.Authenticated = Membership.Providers["ContosoSqlProvider"].ValidateUser(e.UserName, e.Password);
}
else if (e.UserName.IndexOf("@fabrikam.com") >= 0)
{
e.Authenticated = Membership.Providers["FabrikamSqlProvider"].ValidateUser(e.UserName, e.Password);
}
else
{
e.Authenticated = Membership.Provider.ValidateUser(e.UserName, e.Password);
}
e.AuthenticationIsComplete = true;
}
Sub AuthenticationService_Authenticating _
(ByVal sender As Object, _
ByVal e As System.Web.ApplicationServices.AuthenticatingEventArgs)
If (e.Username.IndexOf("@contoso.com") >= 0) Then
e.Authenticated = Membership.Providers("ContosoSqlProvider").ValidateUser(e.Username, e.Password)
ElseIf (e.Username.IndexOf("@fabrikam.com") >= 0) Then
e.Authenticated = Membership.Providers("FabrikamSqlProvider").ValidateUser(e.Username, e.Password)
Else
e.Authenticated = Membership.Provider.ValidateUser(e.Username, e.Password)
End If
e.AuthenticationIsComplete = True
End Sub
Remarks
You create a handler for the Authenticating event when you want to customize how the user's credentials are authenticated at run time. The AuthenticatingEventArgs class supplies values to any Authenticating event handler. By using the properties available in this class, you can retrieve the user credentials to customize authentication.
The AuthenticationService class raises the Authenticating event before validating the user credentials. The AuthenticationService class constructs an instance of the AuthenticatingEventArgs object and passes it to any Authenticating event handler.
You can use the UserName, Password and CustomCredential properties to retrieve the user credentials. The CustomCredential property can contain additional values that are required for authentication, such as an identification number.
The Authenticated property indicates whether the user credentials are valid. You set the Authenticated property to the result of your customized authentication. In addition, you set the AuthenticationIsComplete property to true
if you have checked the user credentials and do not want the AuthenticationService class to check user credentials through the default membership provider.
