# Settings for SSO
If you enabled SSO to log in to your 4ALLPORTAL, you can as well use SSO to log in to the PowerPoint Plugin (from version 5.0).
To enable SSO for your plugin, the following settings must be made (regardless of whether you are using SAML or LDAP as your authentication provider):
# AppDomain Settings
Go to admin snap-in DAM/PowerPoint Plugin.
Check field "AppDomains" and enter all domains your SSO connector calls. Otherwise, the authentication opens in another window, which prevents a working connection between the 4ALLPORTAL and PowerPoint.
# Security Settings
- Go to admin snap-in
General system configurations/System settings/Security. - Check field "Cookie SameSite" and select value "none".
