I see this allowed in selinux-policy-3.10.0-150.fc17 selinux-policy-3.10.0-153.fc17 has been submitted as an update for Fedora 17. https://admin.fedoraproject.org/updates/selinux-policy-3.10.0-153.fc17 Package selinux-policy-3.10.0-153.fc17: * should fix your issue, * was pushed to the Fedora 17 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.10.0-153.fc17' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2012-15652/selinux-policy-3.10.0-153.fc17 then log in and leave karma (feedback). I have the same exact problem, and the update to selinux-policy-3.10.0-153.fc17.noarch did not fix it: Here is relevant aureport: 1707. 10/18/2012 15:26:21 nslcd system_u:system_r:nslcd_t:s0 42 tcp_socket name_connect system_u:object_r:ldap_port_t:s0 denied 11939 I restarted nslcd daemon in case it matters, but did not reboot (shouldn't have to). Fixed.

Allow nslcd to connect to ldap port without boolean
Not fixed for me: rpm -q selinux-policy selinux-policy-3.10.0-156.fc17.noarch Had to do policy tweak as per selinux-troubleshooter instructions to get this to work. Woops. If anyone could remove the hostname from comment 8 that would be splendid. I can make it private, not sure I can modify it. Rob please show us the latest AVC messages. Last AVC in the log before I tweaked policy:

(In reply to comment #11) > I can make it private, not sure I can modify it. If you could make #8 private that would be great; but I can live otherwise.
