# krb5_sname_to_principal - Generate a full principal name from a service name.

krb5_error_code `krb5_sname_to_principal`(krb5_context context, const char * hostname, const char * sname, krb5_int32 type, krb5_principal * ret_princ)

param: | [in] context - Library context [in] hostname - Host name, or NULL to use local host [in] sname - Service name, or NULL to use “host” [in] type - Principal type [out] ret_princ - Generated principal

retval: | 0 Success
return: | Kerberos error codes

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.
