SecureAuth IdP Version Affected: All
Description: When navigating the authentication process, certain embedded browsers will generate an error when trying to navigate the pages. For example, in the Palo Alto Global Protect agent, when you try to go "back" in the process, you get an error like below:
When you search for the exact error, like "__doPostBack is undefined", you find that it is because the browser is unsupported.
Resolution: Follow the steps below to manually identify the embedded browser within the realm. Below we use Palo Alto Global Protect as an example, so you will need to determine the browser name that is embedded, and replace the name below:
1. create D:\SecureAuth\SecureAuthXX\App_Browsers
2. in the folder, create a file called GlobalProtect.browser with the following content:
<browser id="GlobalProtect" parentID="Default">
<userAgent match="GlobalProtect" />
<capability name="ecmascriptversion" value="3.0" />
This tells asp.net that the Global Protect embedded browser supports EcmaScript v.3. There may be other <capabilities> that are needed/desired, so additional testing may be required.
