Trying to configure faillog, and understanding authconfig

How do we configure faillog to login on a "stand-alone" workstation, and how to configure that through authconfig?

I have the https://access.redhat.com/solutions/62949 doc; and have setup the pam files as instructed

this resulted in the gdm bug, but i added the line below:
session optional pam-systemd.so (on the web page i found there was a dash, i.e. -session optional pam-systemd.so) but have tried it with or without the dash.

I end up with either a black screen or when i can login, i get bounced out of the login gui (i.e. desktop shows for a second, and them i am out, so it looks like there is a pam module issue, but Im not sure where the error is, and whether there are additional entries needed in the pam files for Maipo, 7.2.

Thanks
