Thank you Ron and Jon.

Jon, yes they are unique,  I just replaced first word on each line.

I will have to find out how to find these certificates in LDAP and keep all but 
latest as Rob suggested.

I saw this last night and my first thought was this shouldn't happen
because certutil enforces nickname uniqueness.

We would like to verify what each cert is, specifically it's issuer and
serial number. But we can't ask certutil to show us the details of a
cert because you must pass the -n nickname flag to certutil so it can
find the cert to display. But since the nicknames are not unique you
can't do that. This is why certutil (and any low level NSS API that adds
a cert to the db) demands name uniqueness.

Are the names listed with -L truly unique? It looks like you edited them.
