Meru Technical Note - Unable to authenticate against Facebook in IDM?

When we add Facebook as an authentication source and try to authenticate against our Facebook account, it doesn't work due to "Security" policy defined in Facebook account.

To check that you can login to your Facebook account and go to "Settings". Then go to "Security" sub-tab. There is an option "Login approvals", uncheck the box for authentication and Save the settings. 

This is has been fixed in 14.2.0.3 (Bug Number#42928).  In earlier versions, we have to make above changes. Please check the screen shot for reference.
