I would like to pass the userid and password in the itms-services link so that the protected plist can be accessed.
To clarify, in the following link, the plist cannot be accessed directly as the access requires the userid and password to be entered so that plist is accessible.
<a href="itms-services://?action=download-manifest&url=http://example.com/app.plist">
Currently the above link gives an error
cannot connect to example.com
