We store all auth perm strings in upper case, but the user might very well pass this in upper case. We could use a standard key comparator / hash here, but since the strings tend to be small, the new sstring will likely be allocated in the stack here and this approach yields significantly less code. Fixes #1791. Signed-off-by: Glauber Costa <glauber@scylladb.com> Message-Id: <51df92451e6e0a6325a005c19c95eaa55270da61.1477594199.git.glauber@scylladb.com>
