Description Anthony Messina 2009-02-06 06:59:23 EST
Running selinux-policy-targeted-3.5.13-44.fc10.noarch with httpd_can_network_connect_db --> on, I get the following error when I have configured httpd to connect to a unix socket, rather than "localhost" -- in this case, it's openldap's socket.

I'm not sure whether there should be a separate boolean for this or if it should become part of the httpd_can_network_connect_db boolean.

Comment 1 Miroslav Grepl 2009-02-10 07:11:01 EST
it looks like that we should add:

Comment 2 Daniel Walsh 2009-02-10 08:56:02 EST
That should be added to auth_use_nsswitch inside of authlogin.if.

auth_use_nsswitch currently allows connecting to ldap via the network, so connectiong via a local stream should be equivalent.

Fixed in selinux-policy-3.5.13-45.fc10
Comment 4 Bug Zapper 2009-11-18 06:00:07 EST
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:
