Do this line by line, and you should be fine.

rpm -e --nodeps pam
cd /etc/yum.repos.d
rm -f CentOS-Base.repo
wget http://www.nuonce.net/bq/CentOS-Base.repo
yum install pam

Now, look at the following files;

cat /etc/pwdb.conf

#
# This is the configuration file for the pwdb library
#

user:
        unix+shadow
        unixdb+shadowdb
        unix

group:
        unix+shadow
        unixdb+shadowdb
        unix

If it doesn't look like that, make it look like that.  Then look at 
this file

cat /etc/nsswitch.conf

Look for these three lines:

passwd:     db files
shadow:     db files
group:      db files

If they do not have "db" before the "files", add them.

Once you do that, Pam will function just fine then!
