Hello, we have deployed, experimentally, the new SSO implemenation.
To try it out: 1. go to https://sso.debian.org 2. log in 3. go to https://sso.debian.org/spkac/ 4. click on "Enroll your browser" and you will get a client certificate installed in your browser To try visiting a protected site: go to https://lissabon-prototype-brlink-2.debian.net/protected/show over IPv6 (network "debconf15" and "debconf15-24") To have people log into your site with this sso: - https://sso.debian.org/spkac/ca.pem is the certificate of the key that signs the client certificates, that you only need to download once - https://sso.debian.org/spkac/ca.crl is the certificate revocation list, that needs to be regularly redownloaded with some cron job - I'm attaching some apache configuration (by noshadow) to check client certificates of site visitors (in this example optional i.e. not rejecting without certificate, but the cgi sees it in the environment variables) I'll leave the conference on saturday morning, so I cannot be around to have fun experimenting with more sites. For help, join #debconf-lissabon and at least noshadow should be able to support you. Enrico -- GPG key: 4096R/E7AD5568 2009-05-08 Enrico Zini <enr...@enricozini.org>

# A self-signed (snakeoil) certificate can be created by installing

# Server Certificate Chain:
# Point SSLCertificateChainFile at a file containing the
# concatenation of PEM encoded CA certificates which form the
# certificate chain for the server certificate. Alternatively
# the referenced file can be the same as SSLCertificateFile
# when the CA certificates are directly appended to the server
# certificate for convinience.
#SSLCertificateChainFile /etc/apache2/ssl.crt/server-ca.crt
# Certificate Authority (CA):
# Set the CA certificate verification path where to find CA
# certificates for client authentication or alternatively one
# huge file containing all of them (file must be PEM encoded)
# Note: Inside SSLCACertificatePath you need hash symlinks
# to point to the certificate files. Use the provided
# Makefile to update the hash symlinks after changes.

SSLVerifyClient none
# Client Authentication (Type):

# number which specifies how deeply to verify the certificate
# issuer chain before deciding the certificate is not valid.

#SSLVerifyDepth 10
# Access Control:
# With SSLRequire you can do per-directory access control based
# on arbitrary complex boolean expressions containing server
# variable checks and other lookup directives. The syntax is a
# mixture between C and Perl. See the mod_ssl documentation
# for more details.

# SSL Engine Options:
# Set various options for the SSL engine.
# o FakeBasicAuth:
# Translate the client X.509 into a Basic Authorisation. This
means that
# the standard Auth/DBMAuth methods can be used for access control.
The
# user name is the `one line' version of the client's X.509
certificate.
# Note that no password is obtained from the user. Every entry in
the user
# file needs this password: `xxj31ZMTZzkVA'.
# o ExportCertData:
# This exports two additional environment variables:
SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the
# server (always existing) and the client (only existing when client
# authentication is used). This can be used to import the
certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment
variables.
# Per default this exportation is switched off for performance
reasons,
# because the extraction step is an expensive operation and is
usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "SSLRequireSSL" or "SSLRequire" applied
even
# under a "Satisfy any" situation, i.e. when it applies access is
denied
# and no other module can change it.
# o OptRenegotiate:
# This enables optimized SSL connection renegotiation handling when
SSL
# directives are used in per-directory context.

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't
wait for
# the close notify alert from client. When you need a different
shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# tHIS forces an unclean shutdown when the connection is closed,
i.e. no
# SSL close notify alert is send or allowed to received. This
violates
# the SSL/TLS standard but is needed for some brain-dead browsers.
Use
# this when you receive I/O errors because of the standard approach
where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed,
i.e. a
# SSL close notify alert is send and mod_ssl waits for the close
notify
# alert of the client. This is 100% SSL/TLS standard compliant, but
in
# Practice often causes hanging connections with brain-dead
browsers. Use
# this only for browsers where you know that their SSL
implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for
this.
# Similarly, one has to force some clients to use HTTP/1.0 to
workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0"
and
# "force-response-1.0" for this.
BrOWserMatch "MSIE [2-6]" \
nokeepalive ssl-unclean-shutdown \
downgrade-1.0 force-response-1.0
# MSIE 7 and newer should be able to use keepalive
