Source Instances are configured to use SSO for authentication through the UI (browser). However, SSO cannot be used when making web service calls between instances (which is how update sets are moved).

Resolution Remove 'source' field values from the user record Save OR

Navigate to LDAP > Properties Find property " Use LDAP for password authentication " Uncheck the " Use LDAP for password authentication " checkbox The instance falls back to local authentication and will use the password stored in the User record [sys_user.user_password].
