RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Marc Sauton 2021-02-11 00:25:36 UTC 
Description of problem:

the sssd.conf option crl_file=/PATH/TO/CRL/FILE provides support for one CRL PEM file ( ./src/p11_child/p11_child_common_utils.c )

there was a need for a configuration like this:

certificate_verification = no_ocsp,crl_file=/etc/sssd/pki/crl/combinedCRL4.pem,crl_file=/etc/sssd/pki/crl/combinedCRL3.pem,crl_file=/etc/sssd/pki/crl/combinedCRL2.pem

but only 1 CRL can be used:
certificate_verification = no_ocsp,crl_file=/etc/sssd/pki/crl/combinedCRL4.pem


Version-Release number of selected component (if applicable):
RHEL-8.3
sssd-2.3.0-9.el8.x86_64

At this stage this RFE should target RHEL9. Once/if implemented, backport to RHEL8 might be considered.

verified with

[root@ci-vm-10-0-139-177 test_ca]# rpm -qa sssd
sssd-2.7.1-2.el9.x86_64

verification steps:
1. Create localuser1 and also create the key and cert for localuser1
2. Setup virtual card and write key/cert to virtual smart card for localuser1
3. cp /opt/test_ca/crl/root.crl /etc/sssd/root1.crl
4. # revoke the cert previously used
openssl ca -config ca.cnf \
    -revoke /opt/test_ca/localuser1.crt -keyfile rootCA.key -cert rootCA.crt

openssl ca -config ca.cnf \
    -gencrl -out crl/root.crl

# backup crl file for use with sssd
cp /opt/test_ca/crl/root.crl /etc/sssd/root2.crl
5. Write new valid cert for user
6. write cert/key to virtual smartcard
sh -x init_virt_cacard.sh localuser1

# create updated crl
openssl ca -config ca.cnf \
    -gencrl -out crl/root.crl

cp /opt/test_ca/crl/root.crl /etc/sssd/root3.crl

7. Update the sssd.conf
certificate_verification = no_ocsp,crl_file=/etc/sssd/root1.crl,crl_file=/etc/sssd/root2.crl,crl_file=/etc/sssd/root3.crl

cat /etc/sssd/sssd.conf

[root@ci-vm-10-0-139-177 test_ca]# cat /etc/sssd/sssd.conf 
[sssd]
debug_level = 9
services = nss, pam
domains = shadowutils
certificate_verification = no_ocsp,crl_file=/etc/sssd/root1.crl,crl_file=/etc/sssd/root2.crl,crl_file=/etc/sssd/root3.crl

[nss]
debug_level = 9

[pam]
debug_level = 9
pam_cert_auth = True

[domain/shadowutils]
debug_level = 9
id_provider = files

[certmap/shadowutils/localuser1]
debug_level = 9
matchrule = <SUBJECT>.*CN=localuser1*

8. Check authentication of localuser1
[root@ci-vm-10-0-139-177 test_ca]# su - localuser1 -c 'su - localuser1 -c whoami'
PIN for localuser1: 
localuser1

Authentication is successful, thus from the above marking, this bug is verified.
