========
This is an implementation of the GSS EAP mechanism, as described in
-draft-howlett-eap-gss-xx.txt.
+draft-ietf-abfab-gss-eap-01.txt.
Building
========
Heimdal), Shibboleth, and EAP libraries are required, along with
all of their dependencies.
+Note: not all SPIs are supported by the Heimdal mechanism glue,
+so not all features will be available.
+
Installing
==========
+GSS mechglue
+------------
+
When installing, be sure to edit $prefix/etc/gss/mech to register
the EAP mechanisms. A sample configuration file is in this directory.
+You may need to specify an absolute path.
+
+RADIUS client library
+---------------------
Make sure your RADIUS library is configured to talk to the server of
-your choice: see the example radsec.conf in this directory.
+your choice: see the example radsec.conf in this directory. If you
+want to use TCP or TLS, you'll need to run radsecproxy in front of
+your RADIUS server.
+
+RADIUS server
+-------------
+
+These instructions apply to FreeRADIUS only, which is downloadable
+from http://freeradius.org/. After configure, make, install, do the
+following:
+
+On the RADIUS server side, you need to install dictionary.ukerna to
+$prefix/etc/raddb and include it from the main dictionary file, by
+adding:
+
+ $INCLUDE dictionary.ukerna
+
+to $prefix/etc/raddb/dictionary. Make sure these files are world-
+readable; they weren't in my installation.
+
+Edit $prefix/etc/raddb/users to add your test user and password:
+
+ bob@PROJECT-MOONSHOT.ORG Cleartext-Password := secret
+
+Add an entry for your acceptor to $prefix/etc/raddb/clients.conf:
+
+ client somehost {
+ ipaddr = 127.0.0.1
+ secret = testing123
+ require_message_authenticator = yes
+ }
+
+Edit $prefix/etc/raddb/eap.conf and set:
+
+ eap {
+...
+ default_eap_type = ttls
+...
+ tls {
+ certdir = ...
+ cadir = ...
+ private_key_file = ...
+ certificate_file = ...
+ }
+ ttls {
+ default_eap_type = mschapv2
+ copy_request_to_tunnel = no
+ use_tunneled_reply = no
+ virtual_server = "inner-tunnel"
+ }
+...
+ }
+
+to enable EAP-TTLS.
+
+If you want the acceptor be able to identify the user, the RADIUS
+server needs to echo back the EAP username from the inner tunnel;
+for privacy, mech_eap only sends the realm in the EAP Identity
+response. To configure this with FreeRADIUS, add:
+
+ update outer.reply {
+ User-Name = "%{request:User-Name}"
+ }
+
+If you want to add a SAML assertion, do this with "update reply"
+in $prefix/etc/raddb/sites-available/default:
+
+ update reply {
+ SAML-AAA-Assertion = '<saml:Assertion ...'
+ SAML-AAA-Assertion += '...'
+ }
+
+You'll need to split it into multiple lines because of the RADIUS
+attribute size limit.
Testing
=======
appropriately (<host> is the name of the host running the server,
not the RADIUS server).
-% gss-client -port 5555 -spnego -mech "{1 3 6 1 4 1 5322 21 1 18}" \
+% gss-client -port 5555 -spnego -mech "{1 3 6 1 4 1 5322 22 1 18}" \
-user <user> -pass <pass> <host> host@<host> "Testing GSS EAP"
% gss-server -port 5555 -export host@<host>
% client -C -p 5556 -s host -m EAP-AES128 <host>
% server -c -p 5556 -s host -h <host>
+To test fast reauthentication support, add the following to
+/etc/krb5.conf:
+
+[appdefaults]
+ eap_gss = {
+ reauth_use_ccache = TRUE
+ }
+
+This will store a Kerberos ticket for a GSS-EAP authenticated user
+in a credentials cache, which can then be used for re-authentication
+to the same acceptor. You must have a valid keytab configured.
