Call SOAP webservice with NTLM authentication in SA16

[former_SQLA_member1694875]

Hi,

We need to call SOAP webservice which uses NTLM authentication. Is that possible in SQL Anywhere 16 using web client procedure/function (i. e. without using external environments)?

Thanks.

Note: Having never heard of "NTLM authentication" I had to look it up. After a brief look at it, I can say that the server does not have builtin code to do this type of authentication. But... it would seem to me that the server provides you everything that you would need to implement it. I.e. use plain http requests, captures the responses, compose the appropriate reply and send it back to the server. This would take some effort.

It could be easier to use an external environment procedure!

...and then there's this: "Microsoft no longer recommends NTLM in applications"

> "HTLM authentication"

That's a NASA thing.

I fixed my typo 😉

AFAIK, NTLM authentication is not that uncommon within (older) Windows Networks.
