APOP: This is a POP3-specific authentication. Similar to CRAM-MD5, but 
requires storing password in plaintext.

But PAM does not offer access to plain/text, IMHO.

PAM war mir immer schon suspekt.

Ich habe den Bereich auskommentiert und erhalte nun:

Depends on what you which "standard" you mean but I'll just assume
you're using PAM, as suggested by your config.

Looks like you did a kitchen sink configuration in hopes something will work,
but it's probably interfering.  Just "plain" and "login"
is fine.

I don't use PAM, but it looks like you may be a few parameters
short.  Did you install pam/dovecot config?

this is driving me mad. I still can't login.

I started with a fresh doveconfig directory and implemented the 
suf?gestions in the above Document.

Now doveconfig -n gives me:

managesieve_notify_capability = mailto
managesieve_sieve_capability = fileinto reject envelope 
encoded-character vacation subaddress comparator-i;ascii-numeric 
relational regex imap4flags copy include variables body enotify 
environment mailbox date index ihave duplicate mime foreverypart 
extracttext
namespace inbox {
   inbox = yes
   location    prefix }
passdb {
   driver = pam
}
plugin {
   sieve = file:~/sieve;active=~/.dovecot.sieve
}
ssl_cipher_list = 
ALL:!aNULL:!eNULL:!EXPORT:!DES:!3DES:!MD5:!PSK:!RC4:!ADH:!LOW at STRENGTH
ssl_options = no_compression
ssl_prefer_server_ciphers = yes
userdb {
   driver = passwd
}

dovecot status says:
