Apart from full login, Unit4 Identity Services(U4IDS) can also perform "Partial Login". Partial login workflow is completely different than normal or full login, and it redirects users to a custom page where they must search for the tenant they wish to log in to, using domain or company names provided during tenant configuration.

web.config settings

To enable partial login in the U4IDS instance, add the following key to the web config file if it is missing, otherwise set it to true.

<add key="partial-login:enabled" value="true"/>

Once partial login is enabled, the endpoint for partial login is enabled:

https://<idsbasepath>/identity/tenantpartiallogin

The first step for partial login is to search for a tenant which the user wants to log in to, as shown below. The search is based on e-mail or the company name as configured in the tenant configuration. See tenant-configuration.

Based on the user input, all the matching tenants will be listed and the user should select the particular tenant to log into. In the case where there is only one matching tenant, the user will be redirected to the Identity Provider login page directly. If there are multiple matches found for the tenant, then the user will have to select a particular tenant as shown below:

Upon selecting a tenant from the list, the user will be redirected to the log in page of that particular tenant. If more than one Identity Provider is configured for a tenant a screen with Identity Providers selection will be shown:
