you tried to auth as user erickom at metropolitan.org.za via PAM, but your 
/etc/passwd would know erickom only. Hence, try to auth without domain.

Now you try with another passwd driver and access /etc/passwd without PAM, 
but you have a shadowed passwd system. Revert to passdb pam and try the 
username without domain.
