1) First of all, amend file /etc/yum.conf with "multilib_policy=all "
# This is the default, if you make this bigger yum won't see if the metadata
2) above multilib_policy=all option is going to force yum to install the 32 and 64bit version of any package.
3) Then install the missing Linux package with:
- yum install libpwquality
4) This is going to install library /usr/lib/security/pam_pwquality.so
4) When done, restart the System Agent and repeat the validate step in the WCC configuration tab
