dacsinfocard(1) manage InfoCard accounts


dacsinfocard [m[blue]dacsoptionsm[][1]]


This program is part of the DACS suite.

The dacsinfocard command manages accounts that are used by the m[blue]local_infocard_authenticatem[][2] authentication module. This utility serves a similar purpose for these authentication modules that the m[blue]dacspasswd(1)m[][3] command does for its m[blue]local_passwd_authenticatem[][4] module.

Apart from their use by local_infocard_authenticate, these accounts are completely separate from any other accounts.


The digest algorithm used depends on the m[blue]INFOCARD_DIGESTm[][5] directive in effect.

Plaintext PPIDs are not stored. This makes it more difficult for an attacker that gains access to the InfoCard account file to discover PPIDs.

Only a DACS administrator should be able to successfully run this program from the command line. Because DACS keys and configuration files, including the file used to store accounts, must be restricted to an administrator, this will normally be the case, but a careful administrator will set file permissions to deny access to all other users. An ordinary user is able to change his own InfoCard registration using the m[blue]dacs_infocard(8)m[][6] web service.

This program is also available as a DACS web service, m[blue]dacs_infocard(8)m[][6].


The dacsinfocard command recognizes these command line flags:


To list all of the InfoCard accounts configured for the jurisdiction named INFOCARDS:

% dacsinfocard -uj INFOCARDS -list
DSS::INFOCARDS:bob managed,istatic,enabled,passwd
DSS::INFOCARDS:alice managed,istatic,disabled,passwd

To re-enable the alice account:

% dacsinfocard -uj INFOCARDS -ena alice

To test if alice's account is enabled:

% dacsinfocard -uj INFOCARDS -test ena alice
% echo $status

To test if there are accounts for usernames bob and carol:

% dacsinfocard -uj INFOCARDS -test exists carol
% echo $status
% dacsinfocard -uj INFOCARDS -test exists bob
% echo $status

To get the private data for username bob:

% set x=`dacsinfocard -uj INFOCARDS -pdg bob`
% echo "$x"
On vacation


The program exits 0 if everything was fine, and non-zero otherwise. A "false" outcome from the -test operation is reflected by an exit status of 1. An error condition is indicated by an exit status of 2.


As this is a relatively new and complicated feature, please test carefully.
