[Geoserver-users] use REMOTE_USER from environment to set data in WFS-T?

Hi,

I am implementing a simple WFS-T client which access the WFS-T via
digest/basic authentication.

And had the idea to add an 'editor' column, to show who was the last
editor of a point, coming from the 'REMOTE_USER'-environment variable.
Which I think Geoserver will also receive if the service is enabled with
authentication

Question: I know it is possible to use vars from the environment in the
SLD's. But can I also retrieve the value of 'REMOTE_USER' and squeeze
that into the wfs-t request to fill my 'editor' column?

Or other options/ideas to have insight in wfs-t editors?

No, it is not available. We lack the machinery to make the environment cars available, that would be simple enough to add though, but I’m wondering if the wfs protocol allows to use expressions to start with in insert and update… I have no suitable access to the schemas right now (writing from my phone) but I have serious doubts.

Maybe you could try the connection life cycle scripts here:
http://docs.geoserver.org/stable/en/user/data/database/sqlsession.html
They can get the current geoserver user and run some SQL with it, maybe put it in a variable and then use it from a trigger?

Cheers
