Can't authorize at svn server

[ay-b]

Behaviour

docker container logs showing it can't authorize at svn server using provided credentials

Steps to reproduce this issue

1. Configure config.json to access SVN server using svn protocol: "svn://server.domain.com"
2. git svn clone to the /data/id/repo folder since without it container showing "not a working copy" error.
3. Launch the docker-compose

NOTICE: I'm using SASL authentication at the SVN server

Expected behaviour

Normal git svn fetch expected

Actual behaviour

docker-compose logs -f showing:
