Pam_stack.so faulty module or not? Centos 6 Plesk 11.5.30 Update #37

[Shanats]

i am seeing the below error in in /var/log/secure, any insight would be much appreciated

Mar 22 04:14:44 server1234 proftpd: PAM unable to dlopen(/lib64/security/pam_stack.so): /lib64/security/pam_stack.so: cannot open shared object file: No such file or directory
Mar 22 04:14:44 server1234 proftpd: PAM adding faulty module: /lib64/security/pam_stack.so
Mar 22 04:14:44 server1234 proftpd: pam_listfile(proftpd:auth): Couldn't open /etc/ftpusers


[root@server1234 log]# ll /lib64/security/pam_stack.so
ls: cannot access /lib64/security/pam_stack.so: No such file or directory

pam_stack.so really does not exist on the system after tried locating it, neither does /etc/ftpusers

I did some digging, but nothing turn up useful, as any fix apply would basically trigger some other error.

It is CenyOS related issue. Check:

Hi IgorG, Thanks for your reply, i did came across several other suggestion that suggested the same fix, i had noticed that the fix triggered other error, which was what lead me to seeking insight here.

I will make the changes again according to this information and monitor the result.

Thanks again.

Hello Shanats,
Do you mind sharing the results, ie were there any side effects of the instructions you followed?
I ask because someone is facing the same problem and I might be giving him the same URL..

Thanks
