Extranet server- the server keeps all the applications which is being access by only external server.
User ID - All of the above external users are created into the custom directory rather than the NTFS.
Now, My query is, if i want to provide data lever security to the users on external server the how I can
If I use section access then what is should be? is it using NTNAME and password ( I dont think this option will work as the users are external users) and the other one is using USERID and password method by maintaining excel file.
I have worked previously in one of the projects where non NT users are been set up via VPN (But setting up this was IT Help desk) ..on the Qlikview side generally NT users would access using NT Logon for example
Domain\ aliasname and Password
But for external users .. they have added the non NT users to the active directory using their VPN system
for external user the users would logon using just alias without domain name and hostname would be the ipaddress
IMHO you'll need to use NTNAME and fill it with all names of custom users that should get access to your document (and data reduction as well, if needed) NTNAME never comes with a password, as the authentication is performed outside of the document environment (which means authentication is either performed by the QlikView services - for custom users, or by Windows - for Active/Local directory users, or by an external directory service for all others)
Compare this to the USERID/PASSWORD combo where authetication is performed by QlikView when loading and opening the document. In that last case, authentication only relies on the data that is stored in your Section Access table.
Note that whatever you do with USERID/PASSWORD, you will always get a second login prompt.
