83It appears as though you are not an administrator of locker <$targetuser>.
84In order to be able to su to <$targetuser>, you must have full AFS access
85to the root directory of locker <$targetuser>.  Try running the command
86fs sa /mit/$targetuser $curuser all
87on Athena in order to explicitly grant yourself full AFS access.
88Contact scripts\@mit.edu if you are unable to solve the problem.
