Silently fails when management username has underscore

[Infeligo]

When I tried to start the image with environment variable MGMT_USER=admin_user (i.e. containing an underscore), docker-entrypoint.sh silently exited with code 1, providing no additional information. I could not find any info on name restrictions in the user guide also. After removing the underscore the container started smoothly.

Thx @Infeligo for the report. We're moving away from env variable dependant user/password set ups. In Infinispan 10 there will be small yaml file that you can plug in with user/password details. We have some initial prototypes, but we're discussing handling of special characters here.
