8.6.1. User Notification Handler Module

The user notification handler module is used to send emails token owners or administrators in case of any event.

8.6.1.1. Possible Actions

8.6.1.1.1. sendmail

The sendmail action sends an email to the specified email address each time the event handler is triggered.

emailconfig

  • required Option

The email is sent via this SMTP server configuration.

To

  • required Option

This specifies to which type of user the notification should be sent. Possible recipient types are:

  • token owner,

  • logged in user,

  • admin realm,

  • internal admin,

  • email address.

Depending on the recipient type you can enter additional information. The recipient type email takes a comma separated list of email addresses.

reply_to

Adds the specified Reply-To header to the email.

subject

The subject can take the same tags as the body, except for the {googleurl_img}.

mimetype

Possible mime types are:

  • plain (default)

  • html

You can choose if the email should be sent as plain text or HTML. If the email is sent as HTML, you can do the following:

<a href={googleurl_value}>Your new token</a>

Which will create a clickable link. Clicked on the smartphone, the token will be imported to the smartphone app.

You can also do this:

<img src={googleurl_img}>

This will add the QR Code as an inline data image into the HTML email.

Warning

The KEY URI and the QR Code contain the secret OTP key in plain text. Everyone who receives this data has a detailed copy of this token. Thus we very much recommend to never send these data in an unencrypted email!

attach_qrcode

Instead of sending the QR-Code as an inline data image (which is not supported by some email clients (i.e. Outlook) or GMail 1), enabling this option sends the email as a multipart message with the QR-Code image as an attachment. The attached image can be referenced in a HTML body via CID URL 2 with the Content-ID token_image:

<img src="cid:token_image" alt="Token Image" style="..."/>

8.6.1.1.2. sendsms

The sendsms action sends an SMS to the specified number each time the event handler is triggered.

To

  • required Option

Possible recipients are:

  • tokenowner

smsconfig

  • required Option

The SMS Gateway configuration for sending the notification.

8.6.1.1.3. savefile

The savefile action saves a file to a spool directory. Each time the event handler is triggered a new file is saved.

In the pi.cfg file you can use the setting PI_NOTIFICATION_HANDLER_SPOOLDIRECTORY to configure a spool directory, where the notification files will be written. The default file location is /var/lib/privacyidea/notifications/. The directory needs to be writable for the user privacyidea.

filename

  • required option

  • The filename of the saved file. It can contain the tag {random} which will create a 16 characters long alpha numeric string. Thus you could have a filename like notification-{random}.csv.

In addition you can use all tags that can be used in the body also in the filename (some of them might not make a lot of sense!).

Note

Existing files are overwritten.

8.6.1.2. Body for all actions

All actions take the common option body:

body

Here the administrator can specify the body of the notification, that is sent or saved. The body may contain the following tags

  • {admin} name of the logged in user.

  • {realm} realm of the logged in user.

  • {action} the action that the logged in user performed.

  • {serial} the serial number of the token.

  • {url} the URL of the privacyIDEA system.

  • {user} the given name of the token owner.

  • {givenname} the given name of the token owner.

  • {surname} the surname of the token owner.

  • {username} the loginname of the token owner.

  • {userrealm} the realm of the token owner.

  • {tokentype} the type of the token.

  • {registrationcode} the registration code in the detail response.

  • {recipient_givenname} the given name of the recipient.

  • {recipient_surname} the surname of the recipient.

  • {googleurl_value} is the KEY URI for a google authenticator.

  • {googleurl_img} is the data image source of the google authenticator QR code.

  • {time} the current server time in the format HH:MM:SS.

  • {date} the current server date in the format YYYY-MM-DD

  • {client_ip} the client IP of the client, which issued the original request.

  • {ua_browser} the user agent of the client, which issued the original request.

  • {ua_string} the complete user agent string (including version number), which issued the original request.

  • {pin} the PIN of the token when set with /token/setrandompin. You can remove the PIN from the response using the response mangler.

8.6.1.3. Code

This is the event handler module for user notifications. It can be bound to each event and can perform the action:

  • sendmail: Send an email to the user/token owner

  • sendsms: We can also notify the user with an SMS.

  • savefile: Create a file which can be processed later

The module is tested in tests/test_lib_eventhandler_usernotification.py

class privacyidea.lib.eventhandler.usernotification.NOTIFY_TYPE[source]

Allowed token owner

ADMIN_REALM = 'admin realm'
EMAIL = 'email'
INTERNAL_ADMIN = 'internal admin'
LOGGED_IN_USER = 'logged_in_user'
TOKENOWNER = 'tokenowner'
class privacyidea.lib.eventhandler.usernotification.UserNotificationEventHandler[source]

An Eventhandler needs to return a list of actions, which it can handle.

It also returns a list of allowed action and conditions

It returns an identifier, which can be used in the eventhandlig definitions

property actions

This method returns a dictionary of allowed actions and possible options in this handler module.

Returns

dict with actions

property allowed_positions

This returns the allowed positions of the event handler definition. :return: list of allowed positions

description = 'This eventhandler notifies the user about actions on his tokens'
do(action, options=None)[source]

This method executes the defined action in the given event.

Parameters
  • action

  • options (dict) – Contains the flask parameters g, request, response and the handler_def configuration
