One Identity Safeguard for Privileged Sessions 7.5.1 - Creating Custom Credential Store Plugins

Called when the RemoteApp Launcher requests the application credentials. Can be called multiple times for the same session.

• asset

  Type: string

  Description: The asset /database etc./ password requested for.

• connection_name

  Type: string

  Description: The connection name the RemoteApp session uses. This is required if your SPS is linked to SPP.

• session_id

  Type: string

  Description: The unique identifier of the session.

• cookie

  Type: dictionary

  Description: The cookie returned by the previous hook in the session. If this is the first call for that session, it is initialized as an empty dictionary, otherwise it has the value returned by one of the previous calls in this particular custom Credential Store plugin. You can use the cookie to maintain the state for each particular connection or to transfer information between the different methods of the plugin. For an example that transfers information in the cookie between two methods, see Examples in the Creating Custom Authentication and Authorization Plugins.

• session_cookie

  Type: dictionary

  Description: You can use the session cookie to maintain global state between plugins for each particular connection. If this is the first call for that session, it is initialized as an empty dictionary, otherwise it has the value returned by a previous plugin hook in the session.

• protocol

  Type: string

  Description: The protocol name, in lowercase letters (http, ica, rdp, ssh, telnet, vnc).

• client_hostname

  Type: string

  Description: A string containing the hostname of the client, if DNS lookup has been successful. If not, the value of this parameter is None.

• client_ip

  Type: string

  Description: A string containing the IP address of the client.

• gateway_username

  Type: string

• gateway_password

  Type: string

• gateway_groups

  Type: list

• gateway_domain

  string

• target_username - DEPRECATED

  string

• target_host - DEPRECATED

  string

• target_port - DEPRECATED

  Type: int

• target_domain - DEPRECATED

  Type: string

• server_username

  string

• server_ip

  string

• server_hostname

  string

• server_port

  Type: int

• server_domain

  Type: string

• cookie

  Type: dictionary

  Required: no

  Description: The cookie returned by the previous hook in the session. If this is the first call for that session, it is initialized as an empty dictionary, otherwise it has the value returned by one of the previous calls in this particular custom Credential Store plugin. You can use the cookie to maintain the state for each particular connection or to transfer information between the different methods of the plugin. For an example that transfers information in the cookie between two methods, see Examples in the Creating Custom Authentication and Authorization Plugins.

• session_cookie

  Type: dictionary

  Required: no

  Description: You can use the session cookie to maintain global state between plugins for each particular connection. If this is the first call for that session, it is initialized as an empty dictionary, otherwise it has the value returned by a previous plugin hook in the session.

• passwords

  Type: string list

  Required: no

  Description: If the plugin returns multiple passwords, SPS tries to use them to authenticate on the target server (in the order they are listed).

The following example shows a simple plugin that can return both passwords and private keys based on usernames:

class Plugin(object):
    passdb = {
        "user": ["password"],
    }
    privkeydb = {
        "user1": [('ssh-rsa', """

The following example demonstrates how the predefined hooks can be enhanced with additional logic:

        "jack": ["jackspw", ],

                        target_domain=None, gateway_domain=None, gateway_groups=None):

        # Discard "None" parameters, log all other returned parameters
        args = list(inspect.getargvalues(inspect.currentframe()).args)
        logkws = ["{arg}='{value}'".format(arg=arg, value=locals()[arg])
        for arg in args if arg != 'self' and locals()[arg] is not None]

        if "call_count" in cookie:
            call_count = cookie["call_count"]
        else:
            call_count = 0

        logkws.append("call_count='{0}'".format(call_count))

        print ("Retrieving passwords, non-null parameters follow; " + ', '.join(logkws))

        # Return the password list for the user
        pwlist = []
        if target_username in self.passdb:
            pwlist = self.passdb[target_username]
            print "Retrieved passwords;"
        else:
            print "User not found;"

        return {
            "passwords": pwlist,
            "cookie": {"call_count": call_count + 1}
        }

    def authentication_completed(self, session_id, cookie):
        call_count = cookie["call_count"] if "call_count" in cookie else None
        print ("Received notification about completed authentication; "

        call_count = cookie["call_count"] if "call_count" in cookie else None
        print ("Received notification about session end; "
            "call_count='{call_count}'").format(call_count=call_count)
        return None
