It looks like currently we have only 4 option to use for Data Adapters in Webplayer (Prompt, Kerberos, Webconfig and Service Account). Is it possible to consider adding NTLM authentication as well. As we use NTML authentication on the spotfire server so it will be good to have the same on the Data Adapters as well.
Thanks,

NTLM doesn't allow credentials to be delegated (like Kerberos does).
