How to work with authentication?

There are two ways to authenticate database users in RavenDB. The first one is Windows Authentication which requires to provide credentials in the form of a login / password / domain triple. The second option you can choose is OAuth with an API Key. Before you will work with a database in authenticated manner, first you need to go to the RavenDB server and configure an access there. Detailed information about necessary server side work to setup the authentication you will find in a server configuration article Authentication and authorization.

Server recognizes the requested authentication type based on headers of a request sent by the client, so the DocumentStore needs to be properly configured in order to be able to perform any actions against a database with enabled authentication.

Windows Authentication

The DocumentStore has the default authentication credentials corresponded with the current security context in which an application is running. These credentials are taken from CredentialCache object:

ICredentials Credentials = CredentialCache.DefaultNetworkCredentials;

In order to force the DocumentStore to use the custom user credentials you need to overwrite the default ones before calling Initialize method:

DocumentStore windowsAuthStore = new DocumentStore
{
	Credentials = new NetworkCredential("user", "password", "domain")
};

OAuth and API Key

The OAuth configuration is also very simple. You just need to set ApiKey property instead of Credentials. The ApiKey is a string in format apiKeyName/apiKeySecret according to the ApiKeyDefinition stored in the system database. For example for the following key definition:

ApiKeyDefinition
{
	Name = "NorthwindAdminAccess",
	Secret = "MySecret",
	Enabled = true,
	Databases = new List<ResourceAccess>
	{
		new ResourceAccess
		{
			TenantId = "Northwind",
			Admin = true
		}
	}
}

you should create the DocumentStore as below to have the admin access to the Northwind database:

DocumentStore oAuthStore = new DocumentStore
{
	ApiKey = "NorthwindAdminAccess/MySecret"
};

Connection string

The Windows credentials or Api Key can be also specified in the connection string. Look here for more details.
