Cannot load key: Invalid dovecot key version

16 Sep 2020


      I am trying to use a newly added Local Validation functionality in dovecot version 2.3.11.  I am running dovecot inside a Docker container With base  image " debian:buster-slim". When I try to login through below command , a crash is seen. Algorithm Used is RS256 and certificate is self-signed.
