I had no further trouble with load generation of mailserver data on the VMs.
However, since then I wanted to set up things on a different OS (this is on bare metal rather than a VM, but I have been told that should not matter). When I run /opt/SPECimap/load_init.sh I see the following errors reported by "service dovecot status -l". As far as I can tell the test users are set up correctly in /etc/passwd and referred to in /etc/dovecot/passwd.dovecot . The UIDs in /etc/passwd are different than the working VM /etc/passwd but I did not expect that would make a difference?
Can anyone explain the authentication failures?
