# Diagnose user access to a knowledge base

Identify which users have access to a knowledge base and what enables that access.

## Before you begin

Role required: knowledge\_manager, knowledge\_admin, or admin

## Procedure

1.  Access the **User Criteria Diagnostics** landing page using one of these options:

<table id="table_sht_xcv_bdb"><thead><tr><th>

</th><th>

Navigate to

</th></tr></thead><tbody><tr><td>

Using the application navigator

</td><td>

**Knowledge** &gt; **Administration** &gt; **User Criteria Diagnostics**

</td></tr><tr><td>

From a knowledge base

</td><td>

1.  **Knowledge** &gt; **Administration** &gt; **Knowledge Bases**.
2.  Select the knowledge base to diagnose user access.
3.  In the **Related Links** section, click **Run User Criteria Diagnostics**.
 The **User Criteria Diagnostics** landing page appears with the **Select knowledge base** field pre-populated.

</td></tr></tbody>
</table>2.  To diagnose user access:

    1.  In the **Select user** field, select a user.

    2.  From the **Select record type** choice list, select **Knowledge base**.

    3.  In the **Select knowledge base** field, select a knowledge base.

        Every time you select a different user, record type, or knowledge base, the page refreshes and displays data for the selected user.

    4.  Click **Diagnose**.

        The page displays these details:

        -   Whether the user has access to the knowledge base based on their domain. Only system administrators can view domain information and change the domain to give access to a user.
        -   Which user criteria provides read or read and contribute access for this user to the knowledge base and what type of [user criteria definition](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/servicenow-platform/knowledge-management/t_SelectUserCriteria.md) enables this access.
        -   Whether a role that the user has \(knowledge\_manager, knowledge\_admin, or owner of the knowledge base\) enables this access.
        -   For a user with no access to this knowledge base, which user criteria may be modified to grant the access.
