Hi ....

I had installed ProFTP on my Linux-Mandrake (SNF) ...
Now I wanted to test it with
ftp localhost ...

Then I get something like that ...

220 ProFTPD 1.2.5rc1 Server (...) [...
500 AUTH not understood.
500 AUTH not understood.
KERBEROS_V4 rejected as an authentication type
Name (....): anonymous
331 Anonymous login ok, send email ...
Password: test@test.de
530 login incorrect.
Login failes.

Could anybody tell me why .. and what I can do ?
Please help ...

Well ignore the error 500 Auth not understood. That's just mandrake's ftp client that tries to use kerberos for authentication. Your ftp server doesn't support it so it just complains and then goes on with trying to connect normally.
The anonymous account seems to be only partially working though. There could be several things which are going wrong. You have to make sure the user and group you use in the Anonymous bit is a real user, usually would be:
user ftp
group ftp

Also make sure that if that user doesn't have a valid shell that you set:
RequireValidShell off

I think there was more information in the online docs about having problems with logging in through an anonymous account. Try reading the docs at http://proftpd.org

No idea if anybody answer this somewhere else, but I had a similar problem and created the following in my Anonymous block:

User ftp
Group nogroup
UserAlias anonymous ftp
MaxClients 5
RequireValidShell off

please check the INSTALL file, you will find:
If users can not login and your system uses PAM authentication, you may
need to configure PAM to work for FTP. For further details, consult your
system PAM documentation. If you have installed from a package, hopefully
this was done automatically. On Linux systems, the following may work:

#cp -p contrib/dist/rpm/ftp.pamd /etc/pam.d/ftp
