Domino is expected to have enhanced PKCS12 Internet Certificate Management .
Currently as per documented process there is GUI method of importing internet certificates deployed by internal CA outside of Domino to the person documents in the NAB(Domino Directory).
Thus to import the internet certficates to a large number of NAB users uusing GUI is tidiuos as this needs action on each person document individually.(Goal is to put only public keys (*.cer) into the internet certificate field).
Though there are undocumented Lotusscript method of using @Command([PKCS12ImportCertsToNAB] without GUI, but it is expected from Domino to have a better enhanced PKCS12 Internet Certifcate Managament. Where using GUI method this certifcate import can be done to multiple set of users in a go as per requirement.
