[CentOS] pam oddity

CentOS 6.4, 64-bit.

Aug 23 08:32:33 <workstation> kdm: :0[11133]: 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
Aug 23 08:32:33 <workstation> kdm: :0[11133]: PAM adding faulty module:
/lib64/security/pam_gnome_keyring.so

So I do yum provides /lib64/security/pam_gnome_keyring.so, and I get
gnome-keyring-pam-2.28.2-8.el6_3.x86_64 : Pam module for unlocking keyrings
Repo        : base
Matched from:
Filename    : /lib64/security/pam_gnome_keyring.so

6.3? Is this missing from 6.4, or has it been dropped, or what?
