I would be interested if someone else has such a problem.
I have a database that only needs a special user configuration for logging in. It must be user@hostname. The user himself in the database is only the part before the @. I would like to say that changing the username to user@hostname is not an option because the user in question is only the part before the @ in the database.
So far I have managed to do this by rewriting the DBI.pm, Handle.pm and rt-setup-database for the connection. Is there a possibility without having to touch the core software?
I tried to play around with the DatabaseExtraDSN but had no luck so far.
