SSO with Kerberos Authentication-"Upload Protected Area"

Hi All,

I am having EHP1 for NW 7.3 installed on windows 2008 R2 and I am trying to do SSO with ADS.

I am following the steps as below :

1. Created administrator user user1 and disabled "Use Kerberos DES encryption type for this Account" and checked "Password never expire option"
2. setspn -a HTTP/javahost.mydomain.com user1
3. Logged into javahost:port/nwa

1. Generated Keytab file in Domain server:

ktab -a user1@MYDOMAIN.COM -k keytab

1. Imported the keytab into the JAVA system :

http://javahost:port/spnegoKerberos Realm--> edit --> Keys--> Update Keys -> uploading keytab file --> browse --> selected file and IMPORT --> Save.

1. Activate the REALM.
2. Adjusted the authentication stack:

EvaluateTicketLoginModule SUFFICIENTSPNegoLoginModule              OPTIONALCreateTicketLoginModule SUFFICIENTBasicPasswordLoginModule REQUIREDCreateTicketLoginModule REQUIRED-->Save.

1. Did the necessary settings in the browser.When tried to open the URL http://<server>:<port>/XMII/Menu.jsp

I get a Windows security and "Upload Protected Area" message to enter credentials as shown in pictures.

I am able to Login through LDAP User credentials.

It skips SAP login page and but it shows the windows security prompts.How to skip SAP Login page as well as Windows Security Prompts??

Please Help out to resolve this Issue.

Thanks in advance!!!
