KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_sname_to_principal (krb5_contextcontext, const char *hostname, const char *sname, int32_ttype, krb5_principal *ret_princ)

Create a principal for the given service running on the given hostname. If KRB5_NT_SRV_HST is used, the hostname is canonicalized according the configured name canonicalization rules, with canonicalization delayed in some cases. One rule involves DNS, which is insecure unless DNSSEC is used, but we don't use DNSSEC-capable resolver APIs here, so that if DNSSEC is used we wouldn't know it.

Canonicalization is immediate (not delayed) only when there is only one canonicalization rule and that rule indicates that we should do a host lookup by name (i.e., DNS).

Parameters:

context A Kerberos context.
hostname hostname to use
sname Service name to use
type name type of pricipal, use KRB5_NT_SRV_HST or KRB5_NT_UNKNOWN.
ret_princ return principal, free with krb5_free_principal().

Returns:

An krb5 error code, see krb5_get_error_message().
