NAME

       dacs_infocard - Information Card administration

SYNOPSIS

       dacs_infocard [dacsoptions[1]]

DESCRIPTION

       This program is part of the DACS suite.

       The dacs_infocard web service is used:

       ·   to perform a variety of administrative InfoCard functions;

       ·   as a Relying Party to register a self-issued InfoCard, creating an account that can be
           used for authentication. InfoCard-based authentication is performed by
           local_infocard_authenticate[2], a DACS authentication module. These accounts are used
           only by local_infocard_authenticate and are completely separate from any other
           accounts.

       ·   to act on behalf of a Relying Party to validate and extract claim values from a secure
           token created from either a self-issued or managed InfoCard.

           Notes
           ·   Many Identity Selectors can create a self-issued InfoCard, but you must use
               dacs_managed_infocard(8)[3] to create a managed InfoCard.

           ·   If a Relying Party checks that the security token that it receives satisfies the
               validity window condition expressed by the token, as it typically will, then the
               system clocks at the IP/STS (e.g., dacs_sts(8)[4]) and Relying Party must be
               adequately synchronized; see INFOCARD_TOKEN_DRIFT_SECS[5].

           ·   Owing to the InfoCard system architecture, a Relying Party need not have network
               connectivity to a user's IP/STS (e.g., dacs_sts(8)[4]), although the user's
               browser must. This means, for example, that if a user (or his organization)
               operates his own IP/STS, it can be located on the same side of a firewall as the
               user's browser, which may improve the level of security of the IP/STS and any
               sensitive information it may store and access.

           ·   Much of the functionality of this program is also available as a DACS utility,
               dacsinfocard(1)[6], which operates on the same account files.

       Accounts are accessed through DACS's virtual filestore using item type infocards.

           Note
           The official nomenclature for claims can be confusing. In an attempt at consistency
           and simplification, the DACS documentation tries to adhere to the following
           definitions (with the stated compile-time limits):

           Claim
               A pair comprising an attribute name (the Claim type) and an attribute value (the
               Claim value). The attribute value is optional. The number of claims is limited to
               10 static claims and 20 dynamic claims.

           Claim type
               A unique URI[7] that consists of a Claim URI prefix followed by a Claim name. This
               can be thought of as an attribute name.  DACS does not allow the URI to include a
               query or fragment component. A claim type is never dereferenced, it is merely a
               label. Only characters that are valid in a URI are allowed; therefore any invalid
               characters must be properly encoded. Claim types are case sensitive, despite the
               fact that they are URIs. There is a compile-time length limit: 128 characters for
               the URI prefix and 32 characters for the claim name.

           Claim URI prefix
               This URI identifies a namespace in which the Claim name lives (it may not include
               a query or fragment component). Two claim types[8] with different URI prefixes but
               the same claim name are distinct. The InfoCard specification uses the namespace
               http://schemas.xmlsoap.org/ws/2005/05/identity/claims for self-issued claims.
               DACS uses the namespace http://dacs.dss.ca/claims for its claims. These namespaces
               should be treated as "reserved". User-defined claims should live in other
               namespaces, preferably ones over which the user has some authority.

           Claim URI prefix abbreviation
               To avoid the tedious and error-prone task of having to repeatedly enter long Claim
               URI prefix strings, in designated contexts DACS recognizes (but never requires) an
               abbreviation. Two case-sensitive abbreviations are defined: "standard" (equivalent
               to http://schemas.xmlsoap.org/ws/2005/05/identity/claims) and "dacs" (equivalent
               to http://dacs.dss.ca/claims).

           Claim name
               This is a URI path component. When appended to a Claim URI prefix (or paired with
               a Claim URI prefix abbreviation), it forms a Claim type. Only characters that are
               valid in a URI path component are allowed. It is limited to 32 characters.

           Claim value
               This can be thought of as an attribute value. Technically, this is defined as an
               xs:string[9], which is a sequence of XML characters[10]. Claim values are limited
               to 64 characters.

OPTIONS

   Web Service Arguments
       In addition to the standard CGI arguments[11], dacs_infocard understands the following CGI
       arguments:

       OPERATION
           The following operations are supported:

           ·   DELETE

               Delete the account associated with USERNAME. This effectively revokes the
               InfoCard; a self-issued InfoCard may be re-registered, but a managed InfoCard
               becomes unusable.

                   Note
                   The quickest way to delete all accounts is to delete the contents of the
                   infocards item type; e.g., if infocards points to a file, remove the file or
                   copy /dev/null to it.

           ·   DISABLE

               Disable the account associated with USERNAME. InfoCard-based authentication on
               this account will fail; this revokes the InfoCard, but in a reversible way. The
               request is successful if the account is already disabled.

           ·   ENABLE

               Enable the existing account associated with USERNAME. InfoCard-based
               authentication on this account will be possible. The request is successful if the
               account is already enabled.

           ·   LIST

               List all accounts.

           ·   REGISTER

               Register or re-register the submitted InfoCard. Exactly one set of credentials
               must accompany the request, and if registration is successful, the submitted
               InfoCard becomes associated with that identity.

           ·   TOKEN_ATTRVALS

               If the submitted token is valid, display each claim (attribute) value associated
               with the ATTRLIST argument, which consists of zero or more claim names separated
               by a space. If ATTRLIST is absent or the empty string, all claims in the token are
               displayed (note that this is not necessarily all of the claims associated with the
               InfoCard). If any requested claim is not found, the request is ignored (i.e., it
               is not an error). The privatepersonalidentifier claim is displayed in the friendly
               identifier syntax rather than as a base-64 encoded string. The InfoCard
               (self-issued or managed) does not need to be registered at the jurisdiction.

               Three syntaxes are recognized for a claim name. Some claims are "predefined" in
               that they are available in any valid token: issuer, confirm_method, ppid (or
               privatepersonalidentifier), exponent (self-issued only), and modulus (self-issued
               only). The second syntax is the full claim URI (e.g.,
               http://schemas.xmlsoap.org/ws/2005/05/identity/claims/webpage). The third syntax
               uses the DACS shorthand: the word "standard" or "dacs", a colon, and the claim
               name (e.g., standard:webpage). The token is searched for each claim in the
               ATTRLIST, other than the predefined ones.

                   Note
                   Only the full URI syntax can be used to identify claims in an HTML OBJECT's
                   requiredClaims and optionalClaims param tag.

           ·   TOKEN_VALIDATE

               Parse the submitted token and test whether it is valid.

       xmlToken
       AUXILIARY
           This is the submitted InfoCard. It is required for the TOKEN_VALIDATE, TOKEN_ATTRVALS,
           and REGISTER operations. The AUXILIARY parameter name may only be used for this
           purpose if the xmlToken parameter name is not also used.

       FORMAT
           By default, output is emitted in HTML. Several varieties of XML output can be
           selected, however, using the FORMAT argument (please refer to dacs(1)[12] and
           dacs_passwd.dtd[13]). A FORMAT of plain may be useful for programs that need to
           extract claim values; claims are listed one per line with the claim type, followed by
           an "=", followed by the claim value.

       USERNAME
           For some operations, the name of the account to act on.

       For the DELETE, DISABLE, and ENABLE operations, the request must be submitted by the
       account's owner or the DACS administrator.

       Here is an example of a form that might be used to register a self-issued InfoCard:

           <form name="reg_form" id="reg_form" method="post" action="/cgi-bin/dacs/dacs_infocard">
           <table>
           <tr>
           <td>
            <img src="/infocards/ic_image.jpg" onClick="reg_form.submit()"/>
           <object type="application/x-informationCard" name="xmlToken">
            <param name="tokenType" value="urn:oasis:names:tc:SAML:1.0:assertion">
            <param name="issuer" value="http://schemas.xmlsoap.org/ws/2005/05/identity/issuer/self">
            <param name="requiredClaims"
             value="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/privatepersonalidentifier">
            <param name="privacyUrl" value="https://example.com/infocards/privacy_statement.txt">
            <param Name="privacyVersion" value="3">
           </object>
           </td>
           </tr>
           <tr>
           <td align="center">
            <input type="submit" name="infocard_register" value="Register" id="infocard_register" />
           </td>
           <td>
           </td>
           </table>
           <input type="hidden" name="OPERATION" value="REGISTER">
           </form>

DIAGNOSTICS

       The program exits 0 if everything was fine, 1 if an error occurred.

BUGS

       The compile-time limits are fairly arbitrary and only exist to thwart abuse. It should
       probably be possible to specify them at run-time instead.

       XML output is not available yet.

       Registration of a self-issued InfoCard uses the card's PPID (Private Personal Identifier),
       which differs for a given InfoCard for different Relying Parties. The specification does
       not precisely define how two Relying Party endpoints are compared for equality, but if an
       identity selector decides that a jurisdiction's endpoint has changed (e.g., its domain
       name has been reconfigured), all self-issued InfoCards previously registered at the
       jurisdiction will become unusable until they are re-registered.

       This functionality should be integrated with dacs_admin(8)[15].
