This function converts a *hostname* and *sname* into *krb5_principal* structure *ret_princ* . The returned principal will be of the form *sname\/hostname@REALM* where REALM is determined by krb5_get_host_realm(). In some cases this may be the referral (empty) realm.



The *type* can be one of the following:



 
 
	 - KRB5_NT_SRV_HST canonicalizes the host name before looking up the realm and generating the principal.
 
 
 
	 - KRB5_NT_UNKNOWN accepts the hostname as given, and does not canonicalize it.
 
 Use krb5_free_principal to free *ret_princ* when it is no longer needed.
