But why do the logfiles say this directory is missing? As far as i
understood the Login-Process, every imap-login and pop3-login process
is chrooted inside the login folder until the user is authentificated.
In this case it would be necessary to have this folder. When i create
it by hand it is missing the authentification socket. Is this the 
socket "default", normally located inside the login folder? If so,
why is this also not created?

Sorry, i misspresented this. I am not using this configuration when i try
to
set up the single auth-process. Just recognized that it is also possible to
run dovecot in that way. But that's not what i want. The configuration i
posted the very first time is that what i use (now with chroot and
login_dir
set to default).
If i absolutely do not get it running with single auth, i would use
an auth-server for every dovecot instance.
