/***********************************************************************
*
* README for mod_authn_casa
*
***********************************************************************/
INTRODUCTION
mod_authn_casa is an Apache 2.2 Basic Authentication Provider that
can be configured to validate Basic Credentials carrying CASA
Authentication Tokens.
Clients sending CASA Authentication Tokens as part of the Basic Credentials
will format them in the following manner: "username:CasaAuthenticationToken",
where the username is set to "CasaPrincipal" and the CasaAuthenticationToken
is the token string obtained from the CASA Get Authentication Token API..
CONFIGURATION
To use mod_authn_casa as an authentication provider for a specific location
you must first tell Apache that it must load the module, you do this by
placing the module or a link to the module in the Apache server's modules
folder and by placing the following line in the server's httpd.conf file:
LoadModule authn_casa_module modules/mod_authn_casa.so
The following lines show how Apache is configured to use mod_authn_casa
for authenticating requests issued to mod_example:
<Location /example-info>
SetHandler example-handler
AuthType Basic
AuthName "CASA-Authentication"
AuthBasicProvider casa
Require valid-user
</Location>
Note that the name specified in the AuthName directive should match the name
configured under CASA for the authentication realm used by CASA to obtain
identity information for the service.
mod_authn_casa supports the following configuration directives:
UsernameCheck - This is a per-directory or per-location directive which
configures whether or not mod_authn_casa must verify that
the username is set to "CasaPrincipal". Possible values
for this directive are 'on' or 'off'. Default is 'off'.
To enable UsernameChack for a particular location using
CASA Authentication, include the following line inside
the location configuration block:
UsernameCheck on
CLIENT PROGRAMMING NOTES
HTTP Clients sending requests to a location being protected by the CASA
Authentication Provider must obtain an Authentication Token from the CASA
Client for authenticating to the Service identified as the "location" being
accessed in the HTTP Server. In the case of mod_example, the service name
would be "example-info". Once the client obtains an Authentication Token
from the CASA Client it must then include it in the HTTP Basic Authentication
header that it must include in the HTTP Request. The HTTP Basic Authentication
credentials should be in the following form:
Base64("CasaPrincipal":"AuthenticationToken")
SERVER PROGRAMMING NOTES
Apache modules being protected by the CASA Authentication Provider can obtain
the following information about the authenticated identity:
username - This is accessed via the r->user variable or by examining the IdentityId
environment variable associated with the request block. The username is the
user's unique id within the authentication realm. When the authentication realm
is an LDAP database, the username consists of the user's fdn.
Name of the source of identity data (Authentication Realm) - This is accessed by
examining the IdentityDataSourceName environment variable associated with the
request block.
URL to the source of identity data - This is accessed by examining the
IdentityDataSourceUrl environment variable associated with the request block.
Attributes of the authenticated identity - The attributes are set as environment
variables associated with the request block. The environment variable names match
the names of the attributes. The attributes associated with the authenticated
identity and expressed as environment variables are configured at the time that
the service is enabled for CASA Authentication.
Note that environment variables are contained in the r->subprocess_env table.
SECURITY CONSIDERATIONS
CASA Authenticatication Tokens when compromised can be used to either impersonate
a user or to obtain identity information about the user. Because of this it is
important that the tokens be secured by applications making use of them. It is
recommended that the tokens be transmitted using HTTPS.

/***********************************************************************
*
* README for libcasa_s_authtoken
*
***********************************************************************/
INTRODUCTION
libcasa_s_authtoken provides an API for the validation of CASA Authentication Tokens.
The API provides a means for obtaining identity information about authenticated
entities.
Applications should avoid calling directly into this library's APIs. Instead, applications
should code to the PAM API to validate authentication credentials or allow an external
module to perform the credential validation. To facilitate this, CASA Authentication
provides PAM, Apache, and JAAS modules that can be used to validate credentials containing
CASA Authentication tokens,
CONFIGURING TRUSTED AUTHENTICATION TOKEN SERVICES
tbd. Add info about the installation of public certificates and trusted certificate authorities.
CONFIGURING ADDITIONAL IDENTITY TOKEN PROVIDER MODULES
CASA Authentication Tokens contain Identity Tokens. The Identity Tokens contain the identity
information about the entity being authenticated. Identity Tokens can be of different types,
the type utilized for use with a particular service is configured at the time that the service
is configured for CASA Authentication. The default identity token type is CasaIdentityToken.
libcasa_s_authtoken supports different identity token types through an API that allows for the
configuration of different Identity Token Provider plug-ins. An Identity Token Provider plug-in
is configured by placing a configuration file for the plug-ins in the
/etc/opt/CASA/authtoken.d/modules.d folder. The name of the plug-in configuration file is related
to the identity token type in the following manner: IdentityTokenTypeName.conf.
Identity Token Provider plug-in configuration files must must contain a directive indicating the
path to the library implementing the Identity Token Provider plug-in (See the configuration file
for the CasaIdentityToken plug-in for an example).
SERVER APPLICATION PROGRAMMING NOTES
The Validate CASA Authentication Token API is defined in casa_s_authtoken.h.
The API consists of a call to validate authentication tokens. The caller must supply a service
name which must match the service name provided by the client when requesting the authentication
token. Successful calls to the validate authentication token API will return a handle to a principal
interface object. The principal interface object handle can be used to obtain identity information
about the authenticated entity as well as information about the authentication realm. The principal
interface object must be released after it is no longer needed. The amount and type of identity
information associated with the principal interface is dependent on what is configured at the
time that the service is enabled for CASA Authentication.
For examples of code which uses the Validate CASA Authentication Token API look at the implementations
of the CASA Authentication PAM module and the CASA Authentication Provider Apache module.
IDENTITY TOKEN PROVIDER PROGRAMMING NOTES
The Identity Token Provider API is defined in iden_token_provider.h.
For an example see the implementation of the CASA Identity Token Provider.
SECURITY CONSIDERATIONS
CASA Authentication Tokens when compromised can be used to either impersonate
a user or to obtain identity information about the user. Because of this it is
important that the tokens be secured by applications making use of them. It is
recommended that the tokens be transmitted using SSL.

/***********************************************************************
*
* README for casa_identoken
*
***********************************************************************/
INTRODUCTION
casa_identoken is the Identity Token Provider plug-in for tokens of type
CasaIdentityToken. This are the default identity tokens utilized by CASA
Authentication.
CONFIGURATION
The path to the casa_identoken plug-in is configured by placing the file
CasaIdentityToken.conf in the /etc/opt/CASA/authtoken.d/modules.d folder.
PROGRAMMING NOTES
This module does not provide APIs to components outside of the CASA
Authentication framework.
SECURITY CONSIDERATIONS
CasaIdentityTokens are embedded inside CASA Authentication Tokens. CasaIdentityTokens
contain identity information which may be confidential and no attempts are made to
ensure the confidentiality of the data. Because of this it is important that CASA
Authentication Tokens be secured by applications making use of them. It is recommended
that CASA authentication tokens be transmitted using SSL.

/***********************************************************************
*
* README for pam_casaauthtok
*
***********************************************************************/
INTRODUCTION
pam_casaauthtok is a PAM authentication module which can be configured
to validate credentials consisting of CASA Authentication Tokens.
CONFIGURATION
To use pam_casaauthtok as a PAM authentication module for your service,
add the following line to the service's PAM configuration file:
auth required pam_casaauthtok.so
pam_casaauthtok supports the following input parameters:
U - This parameter tells pam_casaauthtok that it must verify that
the username is set to "CasaPrincipal". If the parameter is not
specified then pam_casaauthtok does not check the username.
CLIENT PROGRAMMING NOTES
Clients must specify the same service name when requesting Authentication
Tokens from the CASA Client as the service name specified by the server
when opening a PAM handle.
SERVER PROGRAMMING NOTES
Server applications validating credentials containing CASA Authentication
tokens can obtain the following information about the authenticated identity:
username - This is obtained by querying PAM using the pam_get_item() call with
the item type set to PAM_USER. This can also be obtained by querying PAM
using the pam_getenv() call with the variable name set to "IdentityId". The
username is the user's unique id within the authentication realm. When the
authentication realm is an LDAP database, the username consists of the user's fdn.
Note that PAM applications using pam_casaauthtok need to set username to
"CasaPrincipal" when opening a PAM handle and then the variable is updated by
pam_casaauthtok during the authentication process with the identity information
of the authenticated entity.
Name of the source of identity data (Authentication Realm) - This is obtained
by querying PAM using the pam_getenv() call with the variable name set to
"IdentityDataSourceName".
URL to the source of identity data - This is obtained
by querying PAM using the pam_getenv() call with the variable name set to
"IdentityDataSourceUrl".
Attributes of the authenticated identity - The attributes are set as environment
variables associated with the PAM handle. The environment variable names match
the names of the attributes. The attributes associated with the authenticated
identity and expressed as environment variables are configured at the time that
the service is enabled for CASA Authentication.
EXAMPLE SERVER APPLICATION
See test/test.c for an example application using PAM to authenticate credentials
consisting of CASA Authentication Tokens.
SECURITY CONSIDERATIONS
CASA Authenticatication Tokens when compromised can be used to either impersonate
a user or to obtain identity information about the user. Because of this it is
important that the tokens be secured by applications making use of them. It is
recommended that the tokens be transmitted using SSL.
