Matthias Heszlig Posted July 17, 2023 Share Posted July 17, 2023 Hi all, a customer did a security audit in which one result was that their Storefront servers use NTLM authentication. The customer wants to disable NTLM in his domain entirely. Unfortunately, I could not find any documentation on this issue, so I checked my lab (Virtual Apps and Desktops 2203 LTSR CU2) where I could find the same NTLM authentication events. To see what happens, I set the domain controllers policy to deny all NTLM authentication requests. Now storefront is still working fine and the events are gone. Does anybody know if there is a official documentation that NTLM can be disabled for Storefront servers? Link to comment Share on other sites More sharing options...
Jonathan Adams1709163648 Posted August 15, 2023 Share Posted August 15, 2023 StoreFront does require NTLM for syncing subscriptions and credentials between StoreFront servers in a server group. 1 Link to comment Share on other sites More sharing options...
George Perkins1709160940 Posted January 3 Share Posted January 3 @Jonathan Adams1709163648Can you please provide a citation in the Citrix documentation where it is shown that NTLM is a requirement? Kerberos has been available over 10 years with statements of direction from Microsoft to do new development to eliminate NTLM. NTLM is no longer secure. I agree with @Matthias who posted the question it is a requirement to disable NTLM in our domain. I'd like to configure Citrix to allow that. How?
