Hi, this is a suggestion I was thinking about as I start designing a Moodle Network base Moodle farm.
Having many difficulties to get a role being allowed to see the Network Server block in a course (capability : mnetlogintoremote at CONTEXT_SERVER level ), I downgraded the context to CONTEXT_COURSE in block_mnet_hosts block, with the nice effect to be able to make a course enrolment based selection of users using a cross-site portal (Hey !! I'm master of the keys !! ). Course based cross-platform transfers need also changing the auth/mnet/auth.php start_jump_session() function to downgrade the context either.
It there a problem doing this ?
Thanks for comments.
