Hi List,

OS = SL Linux 4.1 x86_64 (with latest updates)

If I want to connect with the ftp (proftpd) server, I get the following
error message.

Nov 10 14:09:49 linuxsrv3 proftpd[3785]: linuxsrv3.feltengmbh.de
(192.168.1.68[192.168.1.68]) - FTP session opened.

(192.168.1.68[192.168.1.68]) - PAM(stefan): Module is unknown.

The solution is here.

I checked the /lib/security/ folder, and those files do exist, and they have
all of the right ownership and permissions.
One of the other things I mentioned was that I was using SL Linux x86_64.
My install has two lib folders. /lib/ and /lib64/ and they each contain a
security folder with all of the PAM modules.
I changed my /etc/pam.d/ftp file to point into the /lib64/security/ folder
and IT WORKED.
I could log in.

I just looked at a bunch of the other pam.d files, and I noticed that many
of them were pathless in their definition of specific PAM modules.
I tried this in the pan.d/ftp file, and it still worked.
There must be some configuration in pam that allows it to find the correct
module.

I suggest that in future releases that the ftp file should not list explicit
paths.

I hope this helps someone else.
