Dozuki Single Sign On
Single Sign On is not available in your current plan.
Dozuki SSO allows the users of your site to be automatically signed in when they visit your Dozuki site. To make this as simple as possible, we provide a canonical implementation which you can copy and alter and may be all you need.
- Your Site
- The website whose user signin state will be shared with your Dozuki site.
- Your Dozuki Site
- The dozuki.com website that users will be automatically signed in to.
- Remote Authentication URL
- The URL on your site of the page you create from below.
What You Need To Do
Pick a URL on your site for remote authentication
It can be whatever you want, but it must be accessible by all users, even those that are not signed in.
Create a page that responds to that URL
The page should follow the below logic:
- If the register URL parameter is set to "1", send the user to your register/signup page, and then back to your Remote Authentication URL.
- If the logout URL parameter is set to "1", the user has just logged out of Dozuki. You should show them a 'logged out' page or send them someplace that won't immediately send them back to Dozuki.
- If the user is not signed in, send them to your signin page, and then back to this same URL.
- Build a URL encoded HTTP query string of the required parameters (exclude the question mark)
query = "firstname.lastname@example.org&name=George&t=1357604345"
- Compute the hex representation of the SHA1 hash of your SSO secret appended to the end of the query string. Note: the secret should NOT be sent in the query string.
hash = hex(sha1(query + secret))
&hash=abcd01234...to the end of your query string
query = query + "&hash=" + hash
- Redirect the user to the URL:
http://fablab-wuerzburg.dozuki.com/Guide/User/remote_loginwith your query string from above appended to the end.
url = "http://fablab-wuerzburg.dozuki.com/Guide/User/remote_login?" + query
Required URL Parameters
The order is only important for the
hash parameter, which MUST be the last parameter.
|userid||A string that uniquely identifies the signed in user. This can be anything that doesn't change: (id, email, username).|
|The user's email address. It must be valid and unique among your users.|
|name||The display name for the user.|
|t||Unix timestamp. The integer number of seconds since Unix EPOCH expressed in GMT.|
|hash||Hex representation of the SHA1 hash from above.|
Optional URL Parameters
|role||Specify role to set or replace the user's permission level. Roles include:
The easiest way to test your implementation is to use the test form in the SSO section of the Manage page for your site.
You can also test your implementation from above by appending
/test to the Dozuki URL to make it
http://fablab-wuerzburg.dozuki.com/Guide/User/remote_login/test Then visit the remote authentication URL on your site. You should be redirected to your Dozuki site and see a Success message, or an explanation of failure.
After using Test mode to verify that your implementation is correct, enable SSO using the management interface and enter your Remote Authentication URL.
If a user is redirected to your remote authentication URL and they are not signed in, you will need to send them to your signin page and then redirect them back to your remote authentication URL once they've been authenticated.
Updating User Information
You can update a user's information by sending a different email, name, or role parameter during SSO login. Please note that a user's userid can never be changed.
To sign a user out of your Dozuki site, send a POST request from your server to
http://fablab-wuerzburg.dozuki.com/Guide/User/remote_logout with the same URL parameters as login. This is useful to make users who sign out of your site also signed out of your Dozuki site. Make this HTTP request from your server and do not direct users to this URL. A successful request results in a blank
204 No Content response.
Here are some examples to make it easier to implement SSO:
Single Sign On: SAML
SAML allows the users of your organization to be automatically signed in when they visit your Dozuki site. By configurating your current Identity Provider for use with Dozuki as a Service Provider, you can administer user accounts through your existing ADFS/LDAP or other SAML provider.
- Identity Provider Entity ID
- The URI (unique resource identifier) of your Identity Provider. May be referred to as the Issuer depending on your Identity Provider.
- Identity Provider URL
- The URL that Dozuki will redirect users to for authentication.
- Identity Provider X.509 Certificate
- The certificate used by Dozuki to verify XML documents from your Identity Provider.
- Logout URL
- The URL that users are redirected to after they logout.
What You Need To Do
Set the Required SAML Settings
SAML settings are accessible at the Admin Security interface. You will need to set the Identity Provider Entity ID, Identity Provider URL, Identity Provider X.509 Certificate, and Logout URL.
If your SAML Identity Provider supports importing settings through a metadata.xml file, there is a link on the same page title SAML Metadata.
Please note that if you are using ADFS as an Identity Provider, you will need to map LDAP Attributes to Outgoing Claim Types in your Claim Rule.
|LDAP Attribute||Outgoing Claim Type|
Set the Optional SAML Settings
|LDAP Attribute||Outgoing Claim Type|
Specify role to set or replace the user's permission level. Roles include:
author & mod. Setting custom attributes will vary depending on your provider
The Identity Provider URL and Logout URL fields have dialogs to test that the SAML URLs given redirect correctly.
