    <h3>AD Compare Plugin</h3>
    <p>This plugin compares the <strong>Managed By</strong> field on Active Directory computer objects 
       against the <strong>Assigned User</strong> in Disco ICT, and reports mismatches.</p>
    <hr />
    <h4>How It Works</h4>
    <ul>
        <li>Loads all active devices from Disco that have a domain computer account</li>
        <li>Looks up each computer in AD and reads the <code>managedBy</code> attribute</li>
        <li>Resolves the <code>managedBy</code> Distinguished Name to a <code>DOMAIN\username</code></li>
        <li>Compares against Disco's <code>AssignedUserId</code></li>
        <li>Reports mismatches: different users, missing assignments, or empty managedBy</li>
    </ul>
    <hr />
    <p>No configuration is required.</p>
