NAME

       dacs_current_credentials - display DACS credentials

SYNOPSIS

       dacs_current_credentials [dacsoptions[1]]

DESCRIPTION

       This program is part of the DACS suite.

       The dacs_current_credentials web service provides information about the credentials that accompany the
       request and the identities described by those credentials. It can be used to determine whether
       credentials are valid, confirm who they belong to, find out which roles are associated with the
       credentials, and so on.

       If user activity[2] data is available, dacs_current_credentials can also return information for the
       identity associated with each valid set of credentials, including the time of the last sign on and a
       description of any sign-on that is still "active" (i.e., has not expired and was not signed off). This
       information can be useful for detecting unauthorized account access, regardless of the authentication
       method used, and other potentially problematic activity.

       The FORMAT argument[3] determines the type of output, with the default being HTML, using the style sheet
       dacs_current_credentials.css[4]. If XML output is selected, a document conforming to
       dacs_current_credentials.dtd[5] is returned, which supplies additional information. The JSON format (RFC
       7159[6]) is also recognized. The previous_auth and active_auth elements appear only when user activity
       tracking data is accessible. The previous_auth element is empty if there are not two or more records of
       authentication activity for the associated identity. For a given identity, an active_auth element is
       present for each authentication event for which there is no corresponding sign off event, other than the
       most recent one, and for which the issued credentials have not expired - these are "active sessions".
       Reauthentication as the same identity does not create a sign off event, however, and signing off (e.g.,
       via dacs_signout(8)[7]) does not necessarily mean that a user agent has destroyed credentials (though
       that is normally the case). Also, a user can unilaterally destroy credentials (e.g., by terminating a
       browser session or removing cookies manually), so not all active sessions necessarily exist.

OPTIONS

   Web Service Arguments
       dacs_current_credentials accepts the following arguments in addition to the standard CGI arguments[8].

       DETAIL
           If "yes", this optional argument requests additional information. It is recognized only in
           conjunction with XML format output. By default, this argument can only be used by a DACS
           administrator (see dacs_admin()[9]). The activity tracking information is returned only if detail is
           requested.

EXAMPLE

       After authenticating[10] as DSS::INFOCARDS:bob, invoke dacs_current_credentials (HTML)[11] to view the
       identity (or identities) stored as a cookie in your browser. Information about the credentials can also
       be returned as XML[12].

FILES
