Can I merge my AD and SSO users?

Yes, under certain conditions. It is possible in administration > authentication > Other authentication methods to set the option remove the domain of logins like login@domain to Yes. This action carries a risk depending on how your SSO application is set up on the provider side.

Danger

If you allow SSO access to external tenants, it is possible that identity theft could occur. For example, I log on with john.doe@mondomaine.com. Generally speaking, you can't have 2 identicals logins on the same tenant. If you have a homonym in the company, the logins will be different. On the other hand, if a namesake from outside the tenant, such as john.doe@gmail.com, logs in, he or she will be able to impersonate you. This option should therefore be limited to SSO applications that use a single tenant.

Why do I get a message telling me my password is empty?

This can happen when you use V2 of the Oauth SSO plugin. Setting up claims and API permissions is necessary for the plugin to work properly. You can follow this article to set up your application.

Why do I get an error message telling me that I don't have access rights to the application?

This happens when the authorisation rules have not been set up. In fact, once authentication has been successfully completed, GLPI checks that you have an assigned authorisation. GLPI also checks that a rule has been set up to assign you one automatically. If this is not the case, access to GLPI will be denied. To set up these authorisation rules, please refer to this article to help you configure them.

Why are some user record fields overwritten after authentication with OAuth SSO?

This can happen if your OAuth SSO authentication source is also the provisioning source. If the option Fetch information from user profile (available from Setup > Oauth SSO applications) is set to No, Oauth SSO will not retrieve information from user records. If you wish to retrieve user information, change this option to Yes and make sure that the fields in Setup > Authentifcation > Other authentication methods and the claims of your OAuth SSO application are filled in (more information here).

If, on the other hand, you have an external provisioning source such as SCIM, and the Fetch information from user profile option is set to Yes, OAuth SSO will overwrite the current information and replace it with the information entered in Setup > Authentication > Other authentication methods. We therefore recommend that you set this option to No if you have an external provider (more information here).
