Sudo Login (or Masquerade) allows Administrators to log in as any regular user without asking for their password and without disconnecting them. Specially useful for configuring their workspace (filters, reports, dashboard) or to support users (reproduce issues, help them step by step, etc).
gave this add-on stars.
Review:
Doesn't seem to work with SuiteCRM v8 (messes up the view and and makes the the homepage and top menu inaccessible).
