Issue with PAM


I have a lot of lines like this in the "secure" log file:
Quote:
... auth: PAM adding faulty module: /lib64/security/pam_gnome_keyring.so
... auth: PAM unable to dlopen(/lib64/security/pam_gnome_keyring.so): /lib64/security/pam_gnome_keyring.so: cannot open shared object file: No such file or directory
... sshd[...]: PAM unable to dlopen(/lib64/security/pam_gnome_keyring.so): /lib64/security/pam_gnome_keyring.so: cannot open shared object file: No such file or directory
... sshd[...]: PAM adding faulty module: /lib64/security/pam_gnome_keyring.so
... su[...]: PAM unable to dlopen(/lib64/security/pam_gnome_keyring.so): /lib64/security/pam_gnome_keyring.so: cannot open shared object file: No such file or directory
... su[...]: PAM adding faulty module: /lib64/security/pam_gnome_keyring.so
The system is a Slackware64-current server without a graphical interface and does not use ssh keys.
Code:
cd /etc/pam.d/
grep -i -n pam\_gnome\_keyring.so *
Quote:
system-auth:15:auth optional pam_gnome_keyring.so
system-auth:70:session optional pam_gnome_keyring.so auto_start

My guess is that you didn't install gnome-keyring package.
To avoid having those messages in /var/log/secure, you can add a - character at the beginning of the two lines mentioning pam_gnome_keyring.so in file /etc/pam.d/system-auth.
Code:
$ cat /etc/pam.d/system-auth | grep pam_gnome_keyring.so
-auth        optional      pam_gnome_keyring.so
-session     optional      pam_gnome_keyring.so auto_start
The reason is given here

Quote:
...
If the type value from the list above is prepended with a - character the PAM library will not log to the system log if it is not possible to load the module because it is missing in the system. This can be useful especially for modules which are not always installed on the system and are not required for correct authentication and authorization of the login session.

The solution offered by @gegechris99 is better than just commenting on the two lines.

Commenting the lines with "#" will disable Gnome Keyring if the libs are still available (installed).
Using "-" won't disable it if the libs are still available (installed)

I did not install gnome-keyring or libgnome-keyring and I do not intend if there will be no mandatory packages.
I have no problem with dependencies.
