Hi @cantrip: There's a few different mapping strategies, [described here](https://github.com/xrootd/xrootd/tree/master/src/XrdSciTokens#scitokens-configuration-file). The three options are: - All users from a given issuer are mapped to a single, fixed user. - The subject is mapped to the Unix username. - A [mapfile](https://github.com/xrootd/xrootd/tree/master/src/XrdSciTokens#mapfile-format) that is an ordered list of mapping rules that take the path, group, and subject as an input and, on match, output a username. This is written in JSON and really intended that it is easy to be machine-generated (as opposed to be human-maintained). -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1851#issuecomment-1341151261 You are receiving this because you are subscribed to this thread.
