Introduction

The "servicePrincipalName" and "realm" properties can be used to customize it, example, setting "servicePrincipalName" to "HTTP/www.mycompany.com" and realm to "services.org" will result in the "HTTP/www.mycompany.com@services.org" service principal name being used.

When the "servicePrincipalName" is not specified, the target host from the provided endpoint URL is used to construct one as-is.  To perform canonicalization of this hostname (e.g. if a CNAME record host.example.com points to an A record host-x.example.com, then use "host-x.example.com" when constructing the servicePrincipalName), the "useCanonicalHostname" property can be set to "true".
