Rob, Could you please re-run the scenario with SELinux in permissive mode to gather all possible subsequent denials? # setenforce 0 Reading the description in bz#1870300, I see some tests fail. Do they cover some real scenario? Which RHEL release should the fix target? Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: As part of one of the IPA integration tests (test_epn) certmonger is used to obtain an X.509 certificate for postfix. It is requested with: # ipa-getcert request -f /etc/pki/tls/certs/postfix.pem \ -k /etc/pki/tls/private/postfix.key \ -K smtp/`hostname` \ -D `hostname` \ -O postfix \ -o postfix \ -M 0640 \ -m 0600 \ -w After obtaining the certificate certmonger will change the owner and group to postfix and set the file mode of the certificate and key. This is resulting in the following AVC: type=AVC msg=audit(1597851527.271:2658): avc: denied { fowner } for pid=33471 comm="certmonger" capability=3 scontext=system_u:system_r:certmonger_t:s0 tcontext=system_u:system_r:certmonger_t:s0 tclass=capability permissive=0 The chown is done first with: fchown(fd, uid, gid) followed by the chmod: fchmod(fd, perms) Version-Release number of selected component (if applicable): selinux-policy-3.14.3-52.el8 certmonger-0.79.7-15.el8 Steps to Reproduce: 1. ipa-server-install 2. kinit admin 3. ipa service-add smtp/`hostname 4. the above ipa-getcert command
