NetScaler, version 10.1 build 120.1316.e and above, includes a wizard that prompts you for basic information about your StorageZones Controller environment and then generates a configuration that:
The diagram shows these NetScaler components created by the configuration:
Although authentication to NetScaler is optional, it is a recommended best practice.
To support restricted zones or web access to Connectors, you must perform additional NetScaler configuration after you complete the wizard. The configuration ensures that ShareFile clients send credentials only when logged on to a trusted ShareFile domain. To support web access to Connectors, you also add a path (/ProxyService) to the content switching policy used for traffic to /cifs and /sp.
Quick links to topic sections:
The Set up NetScaler for ShareFile wizard does not handle the configuration required to use XenMobile as a SAML identity provider for ShareFile. For more information, see Configure ShareFile Single Sign-On with XenMobile 10.
The following steps describe how to use the NetScaler for ShareFile wizard.
You can also access the wizard as follows: Under Mobility, click Configure XenMobile, ShareFile, and NetScaler Gateway.
|Name||A display name for the content switching virtual server.|
|IP Address||The external (public or DMZ) IP address to be used for the content switching virtual server. If you use a DMZ IP address, you must define a Network Address Translation (NAT) mapping from your external firewall address to this DMZ IP address.|
|ShareFile Data||This option is enabled, indicating that you will use the NetScaler connection for StorageZones for ShareFile Data.|
|StorageZone Connectors for Network File Shares/SharePoint||If you use Connectors and you want to perform user authentication at the NetScaler, select the check box.|
|Certificate||Choose a certificate or install one for the content switching virtual server. If you choose to install a certificate, you are prompted to upload the certificate and private key. For standard zones or for restricted zones with an external hostname, certificates must be publicly trusted and not self-signed.|
|StorageZones Controller IP Address||The internal IP addresses for one or more StorageZones Controller servers. These IP addresses define the StorageZones Controller servers as entities inside of NetScaler. If you already added the servers to NetScaler, click Add From Existing and select the servers. |
To use NetScaler for load balancing, enter an internal IP address for each StorageZones Controller server. To use NetScaler only for SSL and authentication, enter just one IP address.
|Port and Protocol||The port and protocol used for communication from the NetScaler to StorageZones Controllers.|
|AAA VServer IP Address||An unused internal IP address for the Authentication, Authorization, and Auditing (AAA) virtual server. NetScaler creates this virtual server for its own use. The server does not require outside access.|
|LDAP Server IP Address and Port||The IP address and port of your Active Directory server. If you already added an LDAP server to NetScaler, click the Choose LDAP tab and choose the server.|
|Time out||The maximum number of seconds that the NetScaler waits for a response from the LDAP server. Defaults to 3 seconds. The minimum value is 1 second.|
|Single Sign-on Domain||The Active Directory domain name.|
|Base DN (location of users)||The LDAP Base Distinguished Name (DN) where users are stored. Specify the DN using the general form: CN=Users,dc=domain, dc=Net|
|Administrator Bind DN and Password||An administrator account that has permissions to communicate with Active Directory.|
|Logon Name||An LDAP attribute, used by NetScaler to determine whether users log on with their user name or email address. Defaults to sAMAccountName, which enables users to log on with their user names. To require users to enter their email address to log on, change this field to userPrincipalName.|
To support restricted zones or web access to StorageZone Connectors, you must perform additional NetScaler configuration after you complete the NetScaler for ShareFile wizard.
StorageZones Controller uses the Cross-Origin Resource Sharing (CORS) standard to provide the necessary security for requests to restricted zones and from the ShareFile web interface to StorageZone Connectors. CORS uses HTTP headers to allow the client and server to know enough about each other to determine if a request or response should succeed.
As described in the following steps, you will configure the additional virtual server to allow anonymous access from clients for the HTTP OPTIONS verb. The OPTIONS request passes through to StorageZones Controller without being authenticated and without HTTPS callouts to validate the signature. The CORS preflight check validates domain trust before sending credentials.
An understanding of CORS is not needed to perform the configuration. However, for more information about CORS, see http://enable-cors.org/.
Use of Internet Explorer for web access to connectors in restricted zones requires Internet Explorer configuration. For details, see Client requirements for restricted StorageZones.
The additional configuration provides the NetScaler components shown in the following diagram.
Perform the following steps in NetScaler after you complete the NetScaler for ShareFile wizard.
|Name||A policy name, such as SF_ZONE_OPTIONS|
|IP Address Type||Non Addressable|
|Name||A name for the content switching action, such as OPTIONS|
|Target LB Virtual Server||The virtual server added in Step 1|
Click Expression Editor and then build this expression:
Select EQ(String) and type OPTIONS.
The expression should read as follows:
The policy with the lowest value has the highest priority and so is handled first.
The full policy expression should be as follows:
HTTP.REQ.URL.CONTAINS("/cifs/") || HTTP.REQ.URL.CONTAINS("/sp/") || HTTP.REQ.URL.CONTAINS("/ProxyService/")
The full policy expression should be as follows:
HTTP.REQ.URL.CONTAINS("/cifs/").NOT && HTTP.REQ.URL.CONTAINS("/sp/“).NOT && HTTP.REQ.URL.CONTAINS("/ProxyService/").NOT
By default, NetScaler pings the StorageZones Controller server to determine if it is online. However, even if the controller is online, it might not be able to send heartbeat messages to the ShareFile web site. In that case, NetScaler will send traffic to StorageZones Controller although it is not communicating with ShareFile.
To verify StorageZones Controller outbound connectivity to ShareFile, you can create a monitor that checks heartbeat.aspx and bind it to the NetScaler service for each StorageZones Controller.
add lb monitor SZC_Heartbeat HTTP-ECV -send "GET /heartbeat.aspx" -recv "***ONLINE***” -secure YES bind service StorageZone_Svc -monitorName SZC_Heartbeat
StorageZone_Svc is the NetScaler service that corresponds to a StorageZones Controller. That service name is automatically created by the NetScaler for ShareFile wizard. The service name includes the IP address of the controller, such as _SF_SVC_ip-address.
-secure YES is required if the service is listening on port 443.
After you complete the wizard, go to Traffic Management > Load Balancing > Virtual Servers to view the status of the load balancing virtual servers created by the wizard.
