I'm having a problem with a complex (to me, at least) authentication
scheme using OpenLDAP and Apache 2.2.3 and I'm hoping for some advice or
suggestions.
I'm trying to set up an intranet server so that all personnel on desktop
computers within our LAN can access the main areas without
authorization. Folks from outside our LAN have to authenticate using
OpenLDAP to access anything on the intranet site. I've pasted in the
whole included file for apache configuration at the end of this note.
The section below restricts the main DocumentRoot for the web site to
either the IP addresses listed or those who can authenticate with LDAP:
<Directory /var/www/centernet/htdocs>
Options Indexes Includes FollowSymLinks MultiViews
AllowOverride None
# Controls who can get stuff from this server.
AuthType Basic
AuthName "JHU/CCP"
AuthBasicProvider ldap
require valid-user
satisfy any
AuthzLDAPAuthoritative Off
AuthLDAPBindDN "cn=xxxx,dc=jhuccp,dc=org"
AuthLDAPBindPassword "xxxx"
AuthLDAPURL
ldap://localhost:389/ou=ccpperson,dc=jhuccp,dc=org?uid?sub?(objectClass=
*)
order deny,allow
allow from 10.253.192.192/26 10.253.200.0/24 10.253.201.0/24
10.253.202.0/24
deny from all
</Directory>
This section seems to be working correctly; I can view pages in the main
areas from outside our LAN after authenticating. I can also view the
pages from inside our LAN without authenticating.
However, in a separate section, I want to further restrict access to
just records in LDAP and exclude users who are originating from inside
our LAN but don't have records in the LDAP. This section is:
#This uses LDAP to secure access to the /staffonly/ directory
<Directory /var/www/centernet/htdocs/staffonly>
AuthType Basic
AuthName "CCP Staff Only"
AuthBasicProvider ldap
AuthzLDAPAuthoritative Off
satisfy all
AuthLDAPBindDN "cn=xxxx,dc=jhuccp,dc=org"
AuthLDAPBindPassword "xxxx"
AuthLDAPURL
ldap://localhost:389/ou=ccpperson,dc=jhuccp,dc=org?uid?sub?(objectClass=
*)
require valid-user
</Directory>
This too seems to be working correctly from inside our LAN. I can access
everything on the intranet site without authenticating, but if I want
anything in /staffonly/, I have to authenticate. When I do so, I can
access a document, such as /staffonly/test.html.
However, when I try to go directly to
http://centernet.jhuccp.org/staffonly/test.html from a host outside of
our LAN, I get a 403 Forbidden error and this entry in the logs:
[Wed Mar 26 13:19:46 2008] [error] [client 98.218.13.184] client denied
by server configuration: /var/www/centernet/htdocs/staffonly/test.html
When I try to access the pages outside of the /staffonly/ directory from
a host outside of our LAN, everything seems to work correctly after I
enter my credentials.
Can anyone give me any suggestions for troubleshooting or fixing this
problem?
Thanks in advance for any help and advice.
