I'd avoid hiding input fields if the user does not have needed permissions.

IMHO it's better to display input fields always and disable them if the permissions are not granted. (In this case a tooltip with description why it is disabled would be nice.)

(But this is a minor issue, for 1.3 in the small time frame we have it's OK, just put a FIXME note here so we do not forget to fix it in the future.)
