    Thanks, but to change this file I get another problem:

    proftpd: PAM unable to dlopen(/lib64/security/pam_fprintd.so): /lib64/security/pam_fprintd.so: cannot open shared object file: No such file or directory
    proftpd: PAM adding faulty module: /lib64/security/pam_fprintd.so

    I appreciate any help. Thank you.

      Maybe you don’t have /lib64 – Only 64bit operating systems have that directory. Check with uname -a

    Thank you for your post…this saved me after 4 hours of hell trying to figure this out on a virtualmin server that accidentally updated to an unsupported version of proftpd.

    This was a solution to an annoying Login Incorrect issue, had to look in /var/log/secure then searched for the pam errors and lead to this blog.

    THANK YOU for posting.
