Single Sign On cookie, domain and portal URL¶
To edit SSO cookie parameters, go in Manager,
General Parameters >
- Cookie name: name of the cookie, can be changed to avoid conflicts with other LemonLDAP::NG installations
- Domain: validity domain for the cookie (the cookie will not be sent on other domains)
- Multiple domains: enable cross domain mechanism (without this, you cannot extend SSO to other domains)
- Secured cookie: 4 options:
- Non secured cookie: the cookie can be sent over HTTP and HTTPS connections
- Secured cookie: the cookie can only be sent over HTTPS
- Double cookie: two cookies are delivered, one for HTTP and HTTPS connections, the other for HTTPS only
- Double cookie for single session: same as double cookie but only one session is created in session database
- Cookie expiration time: by default, SSO cookie is a session cookie, which means it will be destroyed when browser is closed. You can change this behavior by setting a cookie expiration time. It must be an integer. Cookie Expiration Time value is a number of seconds until the cookie expires. Set a zero value to disable expiration time and use a session cookie.
When you change cookie expiration time, it is written on the user hard disk unlike session cookie
Changing the domain value will not update other configuration parameters, like virtual host names, portal URL, etc. You have to update them by yourself.
Portal URL is the address used to redirect users on the authentication portal by:
- Handler: user is redirected if he has no SSO cookie (or in CDA mode)
- Portal: the portal redirect on itself in many cases (credentials POST, SAML, etc.)
The portal URL must be inside SSO domain. If secured cookie is enabled, the portal URL must be HTTPS.
