The outcome depends on two factors: the **restriction type** (Allow or Block) set when the domain was added, and the domain's current **status** (Active or Inactive). Understanding how these two settings interact helps you configure self-registration access precisely. --- ## Restriction type and status combinations | Restriction type | Domain status | Outcome | Example | | --- | --- | --- | --- | | **Allow** | **Active** | Readers from the domain can self-register | A company adds `@examplecorp.com` to the Allow list with status Active. Employees with `@examplecorp.com` can self-register. | | **Allow** | **Inactive** | Readers from the domain cannot self-register | The domain `@examplecorp.com` is set to Allow, but its status is Inactive. Employees with this domain cannot self-register. | | **Block** | **Active** | Readers from the domain cannot self-register | A general email domain like `@genericmail.com` is added to the Block list with status Active. Users with this domain cannot self-register. | | **Block** | **Inactive** | Readers from the domain can self-register | The domain `@genericmail.com` is in the Block list but its status is Inactive. Users with this domain can self-register. | --- ## How Allow and Block work - **Allow**: Only readers from the specified domains can self-register. All other domains are blocked. - **Block**: Readers from the specified domains are prevented from self-registering. All other domains can self-register. Setting a domain's status to **Inactive** effectively reverses the restriction without removing the domain entry. This allows you to temporarily suspend or reinstate a restriction without deleting and recreating it. --- ## How reader group mapping works with domain restrictions When a domain restriction is set to **Allow** and a reader group is mapped to that domain, readers who self-register with that domain are automatically added to the mapped reader group. If no reader group is mapped to the domain, the default reader group set in the **Content permission** section of the self-registration page applies. If no default group is set either, self-registered readers from that domain will have unrestricted access to the entire knowledge base. If both a default content permission reader group and a domain-specific reader group are configured, the domain-specific reader group takes precedence. --- ## FAQ **What happens if no default reader group is selected?** If no default reader group is selected, self-registered readers will have unrestricted access to the entire knowledge base, without any group-specific restrictions. **What access do readers with multiple group memberships get?** When a reader is part of multiple groups, the highest level of access for each content item is granted. For instance, if a reader belongs to Group A (which has access to all languages in workspace 'V1') and Group B (which has access to only English in 'V1'), the reader will receive access to all languages in workspace 'V1'. **Does individual content access override reader group access?** No, individual content access does not override group access. The reader always receives the highest privilege from both individual and group settings. For example, if a reader is individually set to access only English in workspace 'V2' but is also part of a group that has access to all languages in 'V2', the reader will have access to all languages in 'V2'. **How is reader access prioritized?** Access is determined by the highest privilege assigned at each content level. Readers only gain access to the content they have been specifically granted.
