NTLM authen not available after installing MS Exchange 2013

view story

http://serverfault.com – After installing MS Exchange Server 2013 the SMTP service is running. However when telnetting the host I get 'AUTH' after 'EHLO', rather than 'AUTH NTLM'. I have checked off "integrated Windows authentication' in the security tab. How can I enable NTLM authentication? I have tried Client Frontend servername (port 587) and Default Frondend servername. (port 25) Here is the telnet log: ehlo 250-myhost Hello 250-SIZE 37748736 250-PIPELINING 250-DSN 250-ENHANCEDSTATUSCODES 250-STARTTLS 250-X-ANONYMOUSTLS 250-AUTH 250-X-EXPS GSSAPI NTLM 250-8BITMIME 250-BINARYMIME 250-CHUNKING 250 XRDST (HowTos)
