Hello,

today I run the command "doveadm auth cache flush" for the first time.

# doveadm auth cache flush doveadm(root): Error: userdb lookup:
connect(/var/run/dovecotauth-master) failed: No such file or directory 0 cache entries flushed #

base_dir was the only item contain 'run' and it did not end with a / So I tried to set base_dir to /var/run/dovecot/ and could now rerun "doveadm auth cache flush" without problems.

I compile dovecot from source and found --with-rundir=/var/run/dovecot
as an option to configure. I changed to /var/run/dovecot/, recompile and removed the base_dir
setting in dovecot.conf again.

Now "doveadm auth cache flush" work out of the box. doveconf -d
base_dir is var/run/dovecot/.

Finaly I compiled dovecot with --localstatedir=/var and removed
--with-rundir from configure. The resulting package had again base_dir = /var/run/dovecot so
"doveadm auth cache flush" don't work.

looks like somewhere the missing / should be added in case base_dir
has no trailing / without special configuration.
