ftp,smb and atalk stopped working in FC4

[pi]

 From FC4 ftp seems to be part of the selinux-policy. I have managed the 
httpd part of it, getting different user/public_html to work, so i know 
the syntax to make them ok. When it comes to ftp i cannot find anything 
to read up on and the same goes for smb, wich i need for some pc´s. and 
atalk for macs.

I installed proftpd in favor of vsftpd.

I know i can turn selinux protection off for the specified services, 
but i want it . Can anyone hint me in the right direction here, where i 
can read up on it?

Regards
