Hello,
In my system I have configured auth caching. The problem I have is that
whenever a user changes his password, he/she can't login to dovecot
after a while and the scenarios described at
http://wiki2.dovecot.org/Authentication/Caching are not applied.
I have tried also with "doveadm auth cache flush <login>", but it
didn't work. He also could to login again if he waits for a time or if I
run "doveadm auth cache flush" in the server, flushing all auth
information from cache.
I have attached the log I had when I changed my password (and suffered
the problem). I have attached my doveconf -n too.
