Error: Can't load SSL certificate

[Horst Simon]

The others are on openSUSE 15.4 and macOS, all are binary installs

Entware build options
Build options: ioloop=epoll openssl io_block_size=8192
SQL drivers: mysql
Passdb: checkpassword ldap passwd passwd-file shadow sql
Userdb: checkpassword ldap passwd prefetch passwd-file sql

macOS build options
Build options: ioloop=kqueue notify=kqueue openssl io_block_size=8192
SQL drivers: mysql
Passdb: checkpassword pam passwd passwd-file sql
Userdb: checkpassword passwd prefetch passwd-file sql

openSUSE build options
Build options: ioloop=epoll notify=inotify openssl io_block_size=8192
SQL driver plugins: mysql postgresql sqlite
Passdb: checkpassword ldap pam passwd passwd-file shadow sql
Userdb: checkpassword ldap(plugin) passwd prefetch passwd-file sql

The libz.so are for OpenSUSE and the QNap in the same directories withe the same permissions 
The macOS does not have a libz.so, this dovecot was build by macports.

All servers are running dovecot with the same user accounts.

At the moment I will look into this issue later and will try to authenticate without using
SSL.

On the MACs and openSUSE I authenticate using pam, the QNAP does not use pam
so I want to authenticate using a local password file, but I have problems to set it up correctly

I have changed it 10-auth.conf to use auth-passwdfile.conf.ext and created a password file called userdb.
I don’t know what else to change and what exactly should be in the userdb file.

The log only shows
Mar 20 23:52:45 auth: Debug: auth client connected (pid=6966)
Mar 20 23:52:45 imap-login: Info: Disconnected: Aborted login by logging out (no auth attempts in 0 secs): user=<>, rip=192.168.117.5, lip=192.168.117.2, session=<AhJNZ1T3GcDAqHUF>

I need to fix this first before I can enable SSL again.

Maybe I should open a new threat
