Pureftpd daemon - PureDB doesn't work

[Tornado]

Hi at all!
I've got the following problem:
I installed pureftpd on my lenny machine and configured it according to manuals, tutorials and so on and so on (basicly, i followed a tutorial on debianhelp)

Now, if I start pureftpd like this:

pure-ftpd onestart -l PureDB:/etc/pure-ftpd/pureftpd.pdb

everything works fine.

BUT: If I try to start pure-ftpd-wrapper (manually or inetd tries to start it), it seems, that all config is lost. I can ONLY login with my system users, but not with my virtual ones. I wanted to have it the other way round, no login with sys accounts, only virtual users.

some perhaps helpful information:

Any idea?
Searched google and forums for this but couldn't find any answer

greetings and thanks
