Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Setup server with attachment 1262017 [details] server/key.pem and server/cert.pem
2. Create nssdb with ca/cert.pem certificate marked as trusted
3. tstclnt -d sql:./nssdb/ -h -p 4433

Hubert, I see the upstream bug was fixed for NSS 3.34

Can this bug be marked fixed?

Comment 3 Hubert Kario 2018-03-09 16:46:13 UTC
it's not fixed in nss-3.34.0-4.el7.x86_64

importing a RSA-PSS key to nssdb does not allow the server to use it

Comment 8 Simo Sorce 2019-02-11 15:41:43 UTC
This issue was not selected to be included either in Red Hat Enterprise Linux 7.7 because it is seen either as low or moderate impact to a small amount of use-cases. The next release will be in Maintenance Support 1 Phase, which means that qualified Critical and Important Security errata advisories (RHSAs) and Urgent Priority Bug Fix errata advisories (RHBAs) may be released as they become available. We will now close this issue, but if you believe that it qualifies for the Maintenance Support 1 Phase, please re-open; otherwise we recommend moving the request to Red Hat Enterprise Linux 8 if applicable.
