Mailserver pam_unix authentication failure with dovecot
« on: January 27, 2017, 11:39:28 AM »
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?

We typically use text authentication instead of the pam authentication. Is your VM and bare metal OS the same?

Please follow the ExampleVM scripts and documentation. Please ensure firewall and selinux are disabled.
