WordPress Single Sign-On (SSO) Multisite plugin allows you to configure Single Sign-On (SSO) for WordPress Multisite environment enabling SSO/login using one set of login credentials. You can connect your SAML Identity Provider with all the subsites present under the multisite network and control the SSO flow as well as the rest of the features like Attribute Mapping, Role Mapping, etc in the plugin for all the subsites from the Network level.
In this type of network, the URL of the subsites follow a subdirectory path structure.
For example, if the URL of your main site is abc.com, the subsites will be in the form abc.com/site1, abc.com/site2, etc.
In this network, each subsite will have an individual subdomain on your main domain.
For example, if the URL of your main site is abc.com, the subsites will be in the form site1.abc.com, site2.abc.com, etc.
Apart from the above two structures, WordPress also supports creating totally independent custom domains for each of the subsites.
For example, if the URL of your main site is abc.com, the subsite can be in the form: site1.com, site2.com, xyz.com, etc.
miniOrange WordPress Multisite SSO plugin allows you to enable SSO in any of the above-mentioned multisite networks, allowing your users to log into the multisite network and individual sites by authenticating via your Identity Provider.
In the Multisite Network, install the WordPress SAML 2.0 Single Sign-On (SSO) plugin and activate it. Configure the plugin with the required Identity Provider. Once the plugin is successfully configured, SSO will be enabled for all the subsites in that network. Without Multisite support, you have to configure the WordPress SAML 2.0 Single Sign-On (SSO) Plugin on each site separately, add IdP configuration on each site individually and add Service Provider configuration for each site in the IDP.
For Example: If you have 1 main site with 3 subsites. Then, you have to configure the plugin 3 times on each site, add idp configuration 3 times as well as 3 service provider configurations in your IDP.
With Multi-Site plugin, you have to configure the plugin only once on the network level as well as only 1 Service Provider configuration in the IDP.
WordPress multisite SSO plugin allows you to connect all your subsites with one Identity Provider. There is also an option in the WordPress Multisite SAML SSO plugin where you can enable the SSO for only selected subsites in that network.

The WordPress SAML SSO multisite plugin only needs to be configured once at the Network level. You do not need to configure the plugin individually in each subsite’s dashboard. This allows your users to log into the subsites by authenticating via the Identity Provider that you have configured in the plugin at the Network level. With this, you will also have granular control over the SSO configuration and Attribute/Role mapping for each subsite.
Case 1: A university website has subsites (i.e medical, law, and engineering) each with its own set of students. When doing Single Sign-On using their IDP credentials, students of each subsite should be able to access their separate subsites exclusively based on their education through the main website. In this instance, the users from each subsite should not be able to access the subsite to which they do not belong.
Case 2: An ecommerce website has several subsites (i.e pantry, shopping, kindle). The sole requirement is that customers should be able to authenticate into the main site via their external Identity Provider and have seamless SSO into any of the ecommerce network's subsites. Once the customer authenticates into the main site, they will be able to access any of the subsites without having to authenticate themselves for each one.
Case 3: In this scenario, three separate multisite networks are linked to an external Identity Provider. When a user logs into one of the sites, he or she should be able to log into the other sites as well. When a user creates a session on one site, a session should be established in the other two sites, allowing them to access those sites without having to re-authenticate with the IDP.
