Ok, I indeed found that the auth stuff matches the PDB file.

I've updated this in the CIF reader:

"_atom_site_label_atom_id" -> "_atom_site_auth_atom_id"
"_atom_site_label_comp_id" -> "_atom_site_auth_comp_id"
"_atom_site_label_seq_id" -> "_atom_site_auth_seq_id"
"_atom_site_label_asym_id" -> "_atom_site_auth_asym_id"

for reading the atoms, and for reading the structure parts.
