I installed Redhat 7.2. So it by default installed wu-ftpd ftp server. but its not allowing to connect thru ftp with any existing users in the system. It simple says " Must perform authentication before identifying USER" but anonymous ftp is working....does anyone have solution for this !!!


So, I uninstalled the wu-ftp and installed the proftpd but still no result....still the same error "Must perform authentication before identifying USER" when trying FTP....does anyone have solution for this....I checked the /etc/pam.d/ftp it has

###########
p#%PAM-1.0
auth required /lib/security/pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed

auth required /lib/security/pam_shells.so
account required /lib/security/pam_stack.so service=system-auth
session required /lib/security/pam_stack.so service=system-auth

I think this file is ok...and i also tried various options but no luck !!!

What's the content of /etc/pam.d/system-auth?

I don't know, it looks fine to me. But try configuring your authentication method from authconfig and disable any external authentication method.
