I'm not giving up. :)
I now tried a
net ads join -s /etc/samba/smb3.conf -U samba-admin -d 10
in order to find out what the real problem might be. After a successful
LDAP ping and some other good looking messages, I get the following error:

I understand that ports 445 and 139 are for the CIFS interface which is
disabled in Samba4 as I plan to start Samba in merged-mode and thus the
CIFS interface shall be provided by Samba3. However, a quick test
enabling the CIFS interface in Samba4 resulted in no real difference,
except that a connection on port 445 could be established (though a
connection on port 139 was refused although the port is open according
to a port scan).
Running net ads info successfully delivers information about the server.
However it seems it cannot determine the server's current time.
Running net ads status delivers no information at all. Running it in
debug-mode it says "Could not open connection to LDAP server
guardian.lohrmann.de:389: Transport endpoint is not connected".
Unfortunately I have no more ideas how to identify the problem. Any help
is really appreciated!
Thx
