Apache2::AuthenSecurID::Auth - Authentication handler for Apache2::AuthenSecurID

</Location>
=head1 DESCRIPTION
This module allows authentication against a SecurID server. A request
is redirected to this handler if the authentication cookie does not
exist or is no longer valid. The handler will prompt for username and
passcode. It will then construct and encrypt a UDP packet and send it to
the Ace request daemon. This is necessary since libsdiclient.a needs to
persist for NEXT TOKEN MODE and SET PIN MODE. If the authentication is
valid an encrypted Authentication Cookie is set and the request is redirected
to the originating URI. If the user needs to enter NEXT TOKEN or set their
PIN they will be prompted to do so and if valid the request is then redirected
to the originating URI.
=head1 LIST OF TOKENS
=item *
AuthCryptKey
The Blowfish key used to encrypt and decrypt the authentication cookie.
It defaults to F<my secret> if this variable is not set.
=item *
AuthCookie
The name of the of cookie to be set for the authentication token.
It defaults to F<SecurID> if this variable is not set.
=item *
AuthUserCookie
The name of the of cookie that contains the value of the persons username
in plain text. This is checked against the contents of the encrypted cookie
to verify user. The cookie is set of other applications can identify
authorized users. It defaults to F<SecurID_User> if this variable is not set.
=item *
AuthCookiePath
The path of the of cookie to be set for the authentication token.
It defaults to F</> if this variable is not set.
=item *
AuthApacheCookie
The name of the mod_usertrack cookie. The mod_usertrack module must be
compile and enabled in order to track user sessions. This is set by the
CookieName directive in httpd.conf. It defaults to F<Apache> if this variable
is not set.
=item *
ace_initd_server
The name of the server running the ACE request daemon. This daemon is the
actual process that communicates with the ACE Server. If the user is in
NEXT TOKEN MODE due to repeated failures or SET PIN MODE the Authen::ACE
object must persist beyond the initial request. A request packet is
constructed with a random number, type of transaction, username, passcode
and session identifier. The request packet is then encrypted using Blowfish
and sent to the ACE request daemon. The ACE request daemon decrypts and
parses the packet. The request if forwarded to the ACE server and the
response is sent back to the handler. The random number originally sent is
returned to prevent attacks. It defaults to F<localhost> if this variable
is not set.
=item *
ace_initd_port
The port the that the Ace request daemon listens on. It defaults to F<1969>
if this variable is not set.
=head1 CONFIGURATION
The module should be loaded upon startup of the Apache daemon.
Add the following line to your httpd.conf:
PerlModule Apache2::AuthenSecurID::Auth
=head1 PREREQUISITES
For AuthenSecurID::Auth you need to enable the appropriate call-back hook
when making mod_perl:
perl Makefile.PL PERL_AUTHEN=1
AuthenSecurID::Auth requires Crypt::Blowfish and Crypt::CBC.
For AuthenSecurID::Auth to properly track users mod_usertrack must be
compiled and enabled.
