Description of problem:
KDM needs this access to show the faces in the GUI.
SELinux is preventing /usr/libexec/kde4/kdm_greet from 'read' accesses on the lnk_file .default.face.icon.

*****  Plugin catchall_boolean (89.3 confidence) suggests  *******************

If you want to support NFS home directories
Then you must tell SELinux about this by enabling the 'use_nfs_home_dirs' boolean.
You can read 'None' man page for more details.
Do
setsebool -P use_nfs_home_dirs 1

*****  Plugin catchall (11.6 confidence) suggests  ***************************

If you believe that kdm_greet should be allowed read access on the .default.face.icon lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep kdm_greet /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
