Description Kaushik Banerjee 2012-12-20 15:45:21 UTC
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):

How reproducible:

Steps to Reproduce:
1. Setup sssd for krb5_kpasswd failover. Snippet of domain section as follows:
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.

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.
