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:
SELinux is preventing /usr/libexec/sssd/krb5_child from name_connect access on the tcp_socket
Version-Release number of selected component (if applicable):
selinux-policy-3.7.19-185.el6
How reproducible:
Always
Steps to Reproduce:
1. Setup sssd for krb5_kpasswd failover. Snippet of domain section as follows:
[domain/LDAP-KRB5]
debug_level = 0xFFF0
id_provider = ldap
ldap_uri = ldap://ldapserver.example.com
ldap_search_base = dc=example,dc=com
auth_provider = krb5
krb5_server = kdc1.example.com
krb5_kpasswd = invalidkdc.example.com,kdc1.example.com
2. Try to auth as a user and change password
# ssh -l puser1 localhost
puser1@localhost's password:
Last login: Thu Dec 20 21:06:26 2012 from localhost
-sh-4.1$ passwd
Changing password for user puser1.
Current Password:
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
-sh-4.1$
Actual results:
Password change works. However, an avc appears:
type=AVC msg=audit(1355985410.909:543): avc: denied { name_connect } for pid=15551 comm="krb5_child" dest=464 scontext=unconfined_u:system_r:sssd_t:s0 tcontext=system_u:object_r:kerberos_password_port_t:s0 tclass=tcp_socket
Expected results:
avc shouldn't appear.
