Connecting to Azure
Set Account to the storage account name and set the AccessKey of the storage account to connect. Follow the steps below to obtain these values:
If using Storage as the Backend (default):
- Log into the Azure portal and select Storage Accounts in the services menu on the left.
- If you currently do not have any storage accounts, create one by clicking the Add button.
- Click the link for the storage account you want to use and select Access Keys under Settings. The Access Keys window contains the storage account name and key (you can use either key1 or key2 to connect) that you will need to use in the provider. These properties map to the Account and AccessKey provider connection properties respectively.
If using CosmosDB as the Backend:
- Log into the Azure portal and select Cosmos DB in the services menu on the left.
- Click the link for the Cosmos DB account you want to use and select Connection String under Settings. The Connection String window contains the Cosmos DB account name and primary key that you will need to use in the provider. These properties map to the Account and AccessKey provider connection properties respectively.
Customizing the SSL Configuration
By default, the provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.
Connecting Through a Firewall or Proxy
To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.
In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.
Set the following properties:
- To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
- To tunnel the connection, set FirewallType to TUNNEL.
- To authenticate, specify FirewallUser and FirewallPassword.
- To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.
Troubleshooting the Connection
To show provider activity from query execution to network traffic, use Logfile and Verbosity. The examples of common connection errors below show how to use these properties to get more context. Contact the support team for help tracing the source of an error or circumventing a performance issue.
- Authentication errors: Typically, recording a Logfile at Verbosity 4 is necessary to get full details on an authentication error.
- Queries time out: A server that takes too long to respond will exceed the provider's client-side timeout. Often, setting the Timeout property to a higher value will avoid a connection error. Another option is to disable the timeout by setting the property to 0. Setting Verbosity to 2 will show where the time is being spent.
- The certificate presented by the server cannot be validated: This error indicates that the provider cannot validate the server's certificate through the chain of trust. If you are using a self-signed certificate, there is only one certificate in the chain.
To resolve this error, you must verify yourself that the certificate can be trusted and specify to the provider that you trust the certificate. One way you can specify that you trust a certificate is to add the certificate to the trusted system store; another is to set SSLServerCert.
