Meridix Studio supports single sign on (SSO) from external systems. There are two ways to allow an external system to automatically log in users into Meridix Studio without the users needing to manually input their credentials.
Signed - Recommended
The recommended method to log in users is to make a signed request (same signing mechanism as with the Web API) to the URL https://[meridixurl]/SSO?u=[username] but before sending it use a ticket from Meridix Studio (token/secret) to sign the request resulting in a signed URL ex:
https://companyname.meridix.se/SSO?auth_nonce=acd80a19&auth_timestamp=20121127113000&auth_token=3dsafdsa324c9bd4b8887b66baa8b566c28&u=user@user.com&auth_signature=81987e7899140e0c07e8dc26553fa7d2 The signing procedure is described in the Web API Authorization section.
This is the recommended solution because it nevers send any passwords or ticket secrets to over the wire and once a signed request has been used its no longed valid i.e. each signed URL can only be used once and is only valid for 10 minutes from creation/signing (based on the timestamp parameter in combination with the Meridix server time in UTC).
Basic - Not recommended (insecure)
The easiest way to login a user from an external system is to make a request against https://[meridixurl]/SSO?u=[username]&p=[password]
Where [meridixurl] is the URL to your Meridix installation, [username] is the username/email of the user you want to login and [password] is the Meridix password of the user.
This solution is not the recommended method since its sends the credentials in clear text and should not be used with public installations (available outside e.g. your intranet) and should not be used without SSL (https).
Additional options
You also have the abbility to set the user interface language when logging in a user by using the query string key langage={language_code} where language_code is set to either sv-SE for swedish or en-US for english. If not supplied the system uses the to be logged in users setting.
At the time of writing only english and swedish is supported. But more langages will be supported in upcoming releases.
