Hello Jon,


thank you for your help. responded to main thread, and just sending you the actual output for certutil.


[root@ds01 log]#  certutil -d /etc/pki/nssdb -L

Certificate Nickname                                         Trust Attributes  SSL,S/MIME,JAR/XPI

ARTERIS.COM IPA CA                                           CT,C,C
ARTERIS.COM IPA CA                                           CT,C,C
ARTERIS.COM IPA CA                                           CT,C,C

These nicknames do not look unique to me, I'm assuming you're still editing them for inclusion in this email.

But irregardless here is where I'm going with this. Your goal is to identify the correct cert to use and which to discard. The only way you can do that is to examine each individual cert. To examine an individual cert you must have it's *unique* nickname to pass to "certutil -L -a -n xxx" where xxx is the unique nickname.

Only you can identify the correct cert once you list them. At the absolute minimum they should each have a unique (issuer,serial_number) pair. The one you want to use will probably select based on the issuer and validity dates.

Hello,


I'm having various problem on our FreeIPA setup, like can not establish
new replica server or add a client anymore. Initially we had certificate
issue, then we upgraded the Master FreeIPA server (CentOS 7.0.146) to
FreeIPA v4.4.0) few months back.


On master server it shows up 4 entries for IPA CA certificate. Is this
normal?


[root@ds01 ~]# certutil -d /etc/pki/nssdb -L

Certificate Nickname                                         Trust

        SSL,S/MIME,JAR/XPI

EXAMPLE.COM IPA CA                                           CT,C,C

The question is: are these all different certificates (and why)? I assume someone ran ipa-cacert-manage renew a bunch of times.

Multiple entries in itself shouldn't be a problem.

I assume this is related to your client install issues. You may be able to get away with having just the latest CA cert stored in LDAP to avoid this.

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.
