As noted above, the IPRA will make a reasonable effort to ensure that PCA DNs are accurate. The procedures employed to ensure the accuracy of a CA distinguished name, i.e., the confidence attached to the DN/public component binding implied by a certificate, will vary according to PCA policy. However, it is expected that every PCA will make a good faith effort to ensure the legitimacy of each CA DN certified by the PCA. Part of this effort should include a check that the purported CA DN is consistent with any applicable national standards for DN assignment, e.g., NADF recommendations within North America [5,9].
