Title: #3157: NSSDatabase: fix get_trust_chain
Action: opened
PR body:
"""
In the get_trust_chain method, use certutil -O with the option
--simple-self-signed to make sure that self-signed certs properly
get processed.
Note: this option has been introduced in nss 3.38 and our spec file
already requires nss >= 3.41.
Scenario: when IPA CA is switched from self-signed to externally-signed,
then back to self-signed, the same nickname can be used in
/etc/pki/pki-tomcat/alias for the initial cert and the renewed certs. If
the original and renewed certs are present in the NSS db, running
$ certutil -O -n <IPA CA alias>
produces a complex output like the following (this command is used to find
the trust chain):
"CN=Cert Auth,O=ExtAuth" [CN=Cert Auth,O=ExtAuth]
"caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]
"caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]
The renewal code is disturbed by this output.
If, on the contrary, certutil -O --simple-self-signed -n <IPA CA alias> is
used to extract the trust chain, the output is as expected for a self-signed
cert:
"caSigningCert cert-pki-ca" [CN=Certificate Authority,O=DOMAIN.COM]
As a result, the scenario self-signed > externally signed > self-signed
works.
