NAME
krb5_sname_to_principal, krb5_sock_to_principal - Create a service principal

SYNOPSIS
#include <krb5.h>
krb5_error_code
krb5_sname_to_principal(krb5_context context, const char *hostname, const char *sname, int32_t type, krb5_principal *principal);
krb5_error_code
krb5_sock_to_principal(krb5_context context, int socket, const char *sname, int32_t type, krb5_principal *principal);

DESCRIPTION
These functions create a “service” principal that can, for instance, be used to lookup a key in a keytab. For both these function the sname parameter will be used for the first component of the created principal. If sname is NULL, “host” will be used instead. krb5_sname_to_principal() will use the passed hostname for the second component. If type KRB5_NT_SRV_HST this name will be looked up with gethostbyname(). If hostname is NULL, the local hostname will be used.

krb5_sock_to_principal() will use the “sockname” of the passed socket, which should be a bound AF_INET socket.
