SYNOPSIS

    my $verifier = Wallet::ACL::NetDB::Root->new;
    my $status = $verifier->check ($principal, $node);
    if (not defined $status) {
        die "Something failed: ", $verifier->error, "\n";
    } elsif ($status) {
        print "Access granted\n";
    } else {
        print "Access denied\n";
    }

DESCRIPTION

Wallet::ACL::NetDB::Root works identically to Wallet::ACL::NetDB except that it requires the principal to be a root instance (in other words, to be in the form <principal>/root@<realm>) and strips the /root portion from the principal before checking against NetDB roles. As with the base NetDB ACL verifier, the value of a netdb-root ACL is a node, and the ACL grants access to a given principal if and only if the that principal (with /root stripped) has one of the roles user, admin, or team for that node.

To use this object, the same configuration parameters must be set as for Wallet::ACL::NetDB. See Wallet::Config(3) for details on those configuration parameters and information about how to set wallet configuration.

METHODS

check(PRINCIPAL, ACL)

Returns true if PRINCIPAL is granted access according to ACL, false if not, and undef on an error (see DIAGNOSTICS below). ACL is a node, and PRINCIPAL will be granted access if it has an instance of root and if (with /root stripped off and the realm stripped off if configured) has the user, admin, or team role for that node.

DIAGNOSTICS

Same as for Wallet::ACL::NetDB.

CAVEATS

The instance to strip is not currently configurable.

The list of possible NetDB roles that should be considered sufficient to grant access is not currently configurable.
