Well, after twiddling about I began removing "NO_" argument from my
configuration file.
When I had removed:
NO_TOOLCHAIN=YES
NO_ATM=YES
NO_NIS=YES
NO_SHARE=YES
All started working as it should, i.e. I could login to the console
again and the PAM errors had vanished.
I have attached my configuration in the event anyone else wants to
figure out how or why this problem manifested itself.
