| Android browsers not supported | The igOlapXmlaDataSource component is not supported on browsers for the Android™ operating system. |
|
| Authenticated cross-domain data access not working with the Mozilla Firefox browser | When using the igOlapXmlaDataSource component with authenticated cross-domain access in the Mozilla® Firefox® browser, additional configuration of the Internet Information Service (IIS) is necessary. |
|
| Authenticated data access not working with Internet Explorer 8 and 9 for non-trusted domains | The igOlapXmlaDataSource component cannot retrieve multi-dimensional (OLAP) data on non-trusted domains with the Internet Explorer® browser, versions 8 and 9. |
|
| Authentication popup not displayed in the Chrome browser for cross-domain requests | In the Chrome™ browser, versions 13 or higher, the authentication popup dialog is not displayed by default for cross-domain requests. | |
When using the igOlapXmlaDataSource component with authenticated cross-domain access in the Mozilla Firefox browser, the authentication process does not work due to a bug in the browser (the pre-flight request is registered as un-authenticated). A workaround exists, involving some additional configuration of IIS.
Workaround: Register a custom-managed module in IIS to capture the Firefox’s
OPTIONSverb and complete the response with an authorization header. For details, refer to the Configuring Authenticated Access for the Mozilla Firefox Browser (igOlapXmlaDataSource) topic.
The igOlapXmlaDataSource component cannot retrieve multi-dimensional (OLAP) data on non-trusted domains with the Internet Explorer browser, versions 8 and 9. If the domain, on which the msmdpump.dll HTTP data provider for your SQL Server Analysis Services server is hosted, is not in the trusted domains list of the browser, the browser will not be able to access the server data.
Workaround :The solution can be either of the following:
- Users having these versions of the browser must have the data provider domain added to the trusted sites list of their browsers.
- Host the data provider on a domain trusted by the user’s browser.
In the Chrome browser, versions 13 or higher, the authentication popup dialog is not displayed by default for cross-domain requests. This behavior is prescribed by the browser’s default security policy. (Displaying a credentials popup dialog under such conditions is considered as security risk by the browser’s manufacturer.)
Workaround: The solution can be either of the following:
- Host both your website and the HTTP OLAP data provider (msmdpump.dll) on the same domain
- Start the Chrome browser by setting the -
-allow-cross-origin-auth-promptflag. (If the Chrome browser is started with the--allow-cross-origin-auth-promptflag, the popup is displayed for cross-domain requests, too.)
