OSP was turned off by default in Sakai 10 and removed entirely in Sakai 11.
Permissions for CIG Participant are empty for 2.5 upgrade
: if you are upgrading from a pre-2.5.0 version of Sakai, then you need to force conversion of the OSP permissions by setting
osp.upgrade25=true in your
sakai.properties file. (See also discussion.)
