Error Invoking AccessPoint With URL For SSO

[#1]

I have Qlikview IIS server installed on my system.

I am trying to invoke Access Point from IIS management console via following URL

http://localhost:88/qlikview/index.htm

Note :

1. QV IIS Server is installed on a different webiste (not a default website)

2. All Qlikview Service are stop except the Qlikview Settings Service.

and

3. I change C:\Documents and Settings\All Users\Application Data\QlikTech\WebServer\config.xml file with the IP address of Qlikview Server Machine as follows

<Config>

  <ConfigVersion>11</ConfigVersion>

  <DefaultUrl>http://_/</DefaultUrl>

  <DefaultQvs>192.168.1.222</DefaultQvs>

  <ConfigUrl>http://_:4750/QVWS/Service</ConfigUrl>

  <TunnelUrl>/scripts/QVSTunnel.dll</TunnelUrl>

  <QvsStatusUrl>/QvAJAXZfc/QvsStatus.aspx</QvsStatusUrl>

  <LogLevel>Information</LogLevel>

  <WriteStackTrace>False</WriteStackTrace>

  <UseCompression>True</UseCompression>

  <InstallationPath>C:\Program Files\QlikView\Server\Web Server</InstallationPath>

  <QvsTimeout>60</QvsTimeout>

  <QvsAuthenticationProt>Negotiate</QvsAuthenticationProt>

  <QvpPort>-1</QvpPort>

  <EnableUtilizationLogging>False</EnableUtilizationLogging>

  <SessionCookieTimeOut>-1</SessionCookieTimeOut>

- <AddCluster>

  <Name>Local</Name>

  <LoadBalancing>CpuUsage</LoadBalancing>

  <AlwaysTunnel>False</AlwaysTunnel>

- <AddQvs>

  <Machine>192.168.1.222</Machine>

  <Port>4747</Port>

  <LinkMachineName>192.168.1.222</LinkMachineName>

  <Weight>1</Weight>

  <Username />

  <Password>Encrypted=DxdCGMWfOwU=</Password>

  </AddQvs>

  </AddCluster>

I can access the Access Point without user credentials (as required). However, if I try to invoke Access Point using the IP  address belongs to my machine instead of localhost, it's asking for user credentials, which means SSO isn't working correctly.

What could be the problem?

Looking for your valuable suggestions and help.
