Create a Configuration profile

Then 'custom settings'

Preference Domain : com.apple.MCX

This is what you want in the plist : {cachedaccounts.askForSecureTokenAuthBypass=true}

done!

There is a very good write-up on this here.

But the answer is above???

am i being silly or have i forgotten something ...... ? its still not stopping the prompts ?

Change your Preference domain to com.apple.MCX

SecureTokenBypass is not a preference domain :)

@VitorCostaUK The preference domain is com.apple.MCX.
