FWIW pam is used extensively on Red Hat systems. I'm not aware of any 
glaring problems deserving the recommendation not to use it.

That said I'm no lover of pam, it's not designed well and if it ever got 
replaced I don't think there would be many tears shed. Be that as it may 
it's still central to most system authentication.
