Hello Stefan, I already thought about triggers but then dismissed this approach because I don’t see a way to pass the geoserver user/role (user who starts the WFS transaction) to the database. As I understand it the geoserver uses the jdbc connection that is used to define the datastore and that user then executes the SQL statements. I wouldn’t know how to let the DB know who triggered the XML request to the WFS-T service which would be necessary to map geoserver users to DB roles or set a parameter in the DB.

Geoserver allows setting a session startup sql on the datasource to set a variable. Then the trigger function could use this to prevent the delete action for some users. Beste Grüße Stefan Von meinem Huawei-Mobiltelefon gesendet -------- Originalnachricht -------- Betreff: [Geoserver-users] Restricting WFS-T to certain Transactions Von: michael-haer...@telekom.de<mailto:michael-haer...@telekom.de> An: Geoserver-users@lists.sourceforge.net<mailto:Geoserver-users@lists.sourceforge.net> Cc: Dear List, we currently offer some layers to our users via WFS-T which works quite well but now they requested that only some users are allowed to delete features of a layer and some other may only read and write and others may only read. While I can easily offer solutions for keeping read and write/delete operations separate I have no idea how to separate write and delete if at the same time I need to stick to WFS-T. I consulted the geofence documentation and found write CQL rules and indeed found fine-grained access controls but I didn’t find any solution to restrict access to certain WFS-T operations which are only distinguishable by parsing the contents of the XML body in the WFS-T request. Did I miss something? Can somebody tell me if there is a solution in geofence or does anybody have a different solution based on WFS-T? (I searched the mailing list archive for a solution first but my search for “WFS-T” “write” and “delete” gave me more than 65.000 hits which I could not read all).
