Hello Niclas,
No, currently it is not possible to filter Home Page Actions based on which user is logged on. We have such a request in our Product Backlog. It will be available in one of the future releases.
For now, you can create different Web Interfaces for customers. Alternatively, you can create all-round Home Page Actions that behave differently depending on which user is logged in. For this purpose, you can use value references. When a Home Page Action is executed, the value references will be replaced with property values of the logged in user.
For example, when specifying a container where users can execute a Home Page Action, you can do it like this:
However, you can use value reference %adm-InitiatorDomainDN% instead of a specific domain DN. When the action is executed, the value reference will be replaced with the Distinguished Name of the domain of the logged in user.
In the above scenario, if a user from domain example.com logs in, they will be able to select objects from OU OU=Offices,DC=example,DC=com. However, when a user from domain contoso.com logs in, the OU will be OU=Offices,DC=contoso,DC=com
