I have SharePoint Server 2010 with windows authentication(ntlm).
We are working in java and want to authenticate a user, which is in active directory.
We tried using authentication.asmx but it returned "NotInFormsAuthenticationMode".
I read on the internet that I need to enable forms authentication on my website.
But I don't want to enable forms authentication, so I just want to know is there any way that I can authenticate users without enabling form authentication?
One more question, if I enable forms authentication, will the authentication.asmx authenticate users in active directory?
