Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
The krb5_child process attempts to read ~/.k5login but is denied by SELinux.
Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.7.19-137.el6.noarch
sssd-1.8.0-4.el6.beta3.x86_64
How reproducible:
log into a RHEL6.3 system with SSSD
Steps to Reproduce:
1. log into a RHEL6.3 system with SSSD
Actual results:
AVC denial
Expected results:
no AVC denial
Additional info:
It seems that sssd_t is allowed to read home_root_t but not user_home_t:
# sesearch -s sssd_t -t home_root_t -c dir -p search --allow
Found 1 semantic av rules:
allow sssd_t home_root_t : dir { getattr search open } ;
# sesearch -s sssd_t -t user_home_t -c dir -p search --allow
# (blank)
SELinux contexts:
# ls -ldZ /home/ /home/remote/ /home/remote/jhrozek/
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 /home/
drwxr-xr-x. root root unconfined_u:object_r:user_home_dir_t:s0 /home/remote/
drwxr-xr-x. jhrozek jhrozek unconfined_u:object_r:user_home_t:s0 /home/remote/jhrozek/

Was caused by:
Missing type enforcement (TE) allow rule.
You can use audit2allow to generate a loadable module to allow this access.

The problem is the /home/remote/jhrozek/ directory has bad label and then .k5login is also mislabeled.
$ semanage fcontext -a -e /home /home/remote
$ restorecon -R -v /home/remote
is needed.
