Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. 2. Domain-Based Names for the Kerberos V GSS-API Mechanism In accordance with [DOMAIN-BASED-NAMES] this document provides the mechanism-specific details needed to implement GSS-API [RFC2743] domain-based service names with the Kerberos V GSS-API mechanism [RFC4121]. GSS_C_NT_DOMAINBASED_SERVICE name are mapped to Kerberos V principal names as follows: o the <service> name becomes the first (0th) component of the Kerberos V principal name; o the <hostname> becomes the second component of the Kerberos V principal name; o the <domain> name becomes the third component of the Kerberos V principal name; o the realm of the resulting principal name is that which corresponds to the domain name, treated as a hostname. The same name canonicalization considerations and methods as used elsewhere in the Kerberos V GSS-API mechanism [RFC4121] and Kerberos V [RFC4120] in general apply here. Implementations SHOULD use a Kerberos V name-type of NT-SRV-HST- DOMAIN (integral value TBD)to be assigned, possibly after WGLC?) but MAY use NT-UNKNOWN instead. 3. Examples o The domain based name, of generic form, "ldap@Example.TLD@ds1.Example.TLD" may map to a Kerberos V principal name like: "ldap/ds1.example.tld/ example.tld@EXAMPLE.TLD" o The domain based name, of generic form, "kadmin@Example.TLD@kdc1.Example.TLD" may map to a Kerberos V principal name like: "kadmin/kdc1.example.tld/ example.tld@EXAMPLE.TLD" 4. Security Considerations See [DOMAIN-BASED-NAMES]. 5. Normative [DOMAIN-BASED-NAMES] Williams, N., "GSS-API Domain-Based Service Names and Name Type".
