Hello,

I was receiving the following errors:

In /var/log/proftpd.log
Code:

FTP session opened.
PAM(user_name): Cannot make/remove an entry for the specified session
Preparing to chroot to directory '/var/www/htdocs/whatever
ANON user_name: Login successful.'
FTP session closed.


In the meanwhile /var/log/secure shows:
Code:

proftpd: pam_warn(ftp:session): function=[pam_sm_open_session] service=[ftp] terminal=[/dev/ftpd23815] user=[user_name] ruser=[user_name] rhost=[xxx.xxx.xxx.xxx]
proftpd: PAM prelude-client: Unable to initialize prelude client: could not open '/etc/prelude/profile/PAM/config' for reading: No such file or directory  Profile '
PAM' does not exist. In order to create it, please run: prelude-admin register "PAM" "idmef:w" <manager address> --uid 0 --gid 0.
proftpd: PAM No prelude alert sent


I found HERE as possible cause the following:

Quote:

When configuring proftpd, the configure script will automatically try to determine whether your operating system supports PAM. If it does, the mod_auth_pam module will automatically be compiled into your proftpd. If you explicitly do not want PAM support, you can use the --disable-auth-pam configure option to disable this automatic detection.


And I used this solution:
Quote:

To disable use of PAM entirely, use:
Code:

  <IfModule mod_auth_pam.c>
    AuthPAM off
  </IfModule>



The errors ceased to be logged.

Thanks for the suggestion, proftpd was intentionally build with pam support, but it's good to clean logs from this type of errors...
Although there other apps that have similar errors, unless you switch to PAM of course...

Thanks again

p.s. any update from the samba logs with 4.1.12?
