Bug 565462

Summary:

SELinux is preventing /usr/sbin/winbindd from connecting to port 135.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux has denied winbindd from connecting to a network port 135 which does not
have an SELinux type associated with it. If winbindd should be allowed to
connect on 135, use the semanage command to assign 135 to a port type that
winbind_t can connect to (smbd_port_t, ldap_port_t, dns_port_t, kerberos_port_t,
ocsp_port_t).
If winbindd is not supposed to connect to 135, this could signal a intrusion
attempt.

Allowing Access:

If you want to allow winbindd to connect to 135, you can execute
semanage port -a -t PORT_TYPE -p tcp 135
where PORT_TYPE is one of the following: smbd_port_t, ldap_port_t, dns_port_t,
kerberos_port_t, ocsp_port_t.
