iManager credential page prompting for username, password, tree name and protocol after upgrading appliance from 3.2.2 to 4.0

After upgrading the NAM appliance from 3.2.2 to 4.0 without any visible errors, the iManager login page is prompted not for the username/password, but for username, password, tree name and protocol.

Fixed in NAM 4.1. Can workaround the issue with the following changes:

a) login to iManager and select following field AC Login | Configure button | LFT-PANE: iManager Server | RT-PANE-TAB:Authentication From here, we modified the config with following changes:

(i) Entered the IP address for my AC in the "Default Tree Name" field
(ii) Enabled "Remember login credentials (except password)

This modifies the  /var/opt/novell/iManager/nps/WEB-INF/config.xml so that showtree is set to False (had been set to true after upgrade)

  <setting>^M
    <name><![CDATA[Authenticate.Form.ShowTree]]></name>^M
    <value><![CDATA[false]]></value>^M
  </setting>^M
 <setting>^M
    <name><![CDATA[Authenticate.Form.DefaultTree]]></name>^M
    <value>150.151.152.153</value>^M
  </setting>^M

Non standard upgrade scenario where admin copied the upgrade scripts and files to the ESX server and not the host. From here, the ESX file system was shared with the various guest OSes, so they could run the upgrade.
