I have spent the past few days working to get the latest version working in an all windows environment. I am unable to get kerberos authentication to work. I am struggling with getting the keytab file correct. Wondering if there is anyone who has seen it actually work in an all windows environment. I have had earlier version (v2.X stable) with NTLM authentication, but unfortunately I do not have the binaries to implement in v3.5.x.x. I continue to struggle to find the secret forumula for SPN and keytab.
