Seems to me like a bug in my script you shared here, perhaps the CA cert creation and signing is missing some undocumented arguments for FIPS mode. It could also be a bug in NSS since verification of such created certificate signatures does not fail in non-FIPS environent. Either above mentioned way, changing the component from "ipa" to "nss". Please attach the involved certificates, so we can have a look, without reproducing your environment. Please find the attachment for certificates created in temp directory by given script.

On first look, I don't see an issue with this certificate. 2048 bit RSA key, signature uses sha256, has basic-constraints extension. I assume you are running on a system that has FIPS enabled system-wide, correct? Please clarify: Is this a regression with new a package version, or, are you trying this for the first time? (If regression, please mention the package versions that are working.)

(If regression, please mention the package > versions that are working.) I am trying this for the first time. Is there any specific flags or options required to create certificate using certutil in FIPS mode ? @kai: We're doing this for the first time, it's a part of a RHEL 7.4 feature: https://bugzilla.redhat.com/show_bug.cgi?id=1125174 If you want to speed up analysis, can you find out the exact failing command, including parameters, that is being executed as part of the script? The failure happens in the following code:
"""
intended_usage = nss.certificateUsageSSLCA
try:
approved_usage = cert.verify_now(certdb, True, intended_usage)
"""
where cert is nss.Certificate representing the CA cert that's signing the sub-CA cert.
This is of course python-nss code but given that that won't probably change FIPS/non-FIPS, it's more probable that the failure will happen in the actual nss library.
You don't login. You must ensure that you provide the database password and that PK11_Authenticate() succeeds. Although I am changing the component back to IPA, you should fix this too since the way you handle errors will open cases against you over and over again and that's just a waste of both sides' time.
