Use NTLM Authentication

Remco

I'm implementing a new interface between NAV2013 R2 and an external system. This system calls the NAV webservice from a Linux machine. There for I had to change the setting Use NTLM Authentication in the servicetier. My question is if I just can change this setting or does it have consequences for existing interfaces which use webservices from NAV?

When NTLM is not checked, it will use negotiate (kerberos) to authenticate. Most kerberos clients can also authenticate using NTLM, but I would just setup another servicetier just for NTLM authentication, and point the client to that servicetier.
