public static Agent CreateDbUser(string username)

Warning: This method should be used if there is confidence that in circumstances where an application is deployed, configure the Active Directory will properly execute the code below (if you are not sure, better to use an overload with two parameters)

using (var context = new PrincipalContext(ContextType.Domain))
{
	using (UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(context, username))
	{
		if (userPrincipal != null)
		{
			return CreateDbUser(username, userPrincipal.DisplayName);
		}
	}
}

Features use AuthenticationAdapter

1. The method CreateDbUser in the database are added the following objects:

• The user bound to the domain and to roles, the default (if the corresponding roles are found in the database of the authority).
• User domain, if it is previously absent in the system of authority.

1. The job role is the default config of the application:

<configuration>
	<appSettings>
		<add key="DefaultRoles" value="Администраторы2, AnonimousUser"/>
		<!--...-->
	</appSettings>
	<!--...-->
</configuration>

Example of using AuthenticationAdapter

Use AuthenticationAdapter you can, for example, in the Page_Load event in the Site.Master:

protected void Page_Load(object sender, EventArgs e)
{
	//... 
	ApplyTreeViewCookie();
	//... 
	if (AuthenticationAdapter.GetDbUser(Context.User.Identity.Name) == null)
		AuthenticationAdapter.CreateDbUser(Context.User.Identity.Name);
	//... 
	fio.Text = Context.User.Identity.Name;
	//... 
}

create a user with a filled-in password

If you create a user need to have his password was not equal to NULL, then you need to take the source code of the method 6 and edit it, adding the set value of the password. Then use this method to create users. For example:

public static Agent CreateDbUser(string username, string friendlyUserName, bool addDefaultRoles, IDataService dataService)
{
    string login;
    string domain = DomainHelper.GetDomainFromFullName(username, out login);
 
    var agent = new Agent
    {
        Login = login,
        Pwd = "5D70C3D101EFD9CC0A69F4DF2DDF33B21E641F6A",
        IsUser = true,
        Name = friendlyUserName
    };
 
    var meth = typeof(AuthenticationAdapter).GetMethod(
        "CreateDbAgentWithLinks",
        BindingFlags.Static | BindingFlags.NonPublic);
    meth.Invoke(null, new object[] { agent, domain, addDefaultRoles, dataService });
 
    return agent;
}
