As a research student (PhD student) you have two Lucat IDs, one as student and one as employee. If you are not employed by Lund University (e.g. employment at another university or in a company, or if you have a scholarship) you should anyway have two Lucat IDs. Often the student Lucat ID is the same with an -s after, but not always. You can find your Lucat IDs at lucat.lu.se.
