And this is how it will stay. For internal use, the system will refer to the uid only. Just when it needs to output sth, it will translate the uid to THE username by /etc/passwd, and stop on the first match.

hesiod_free_passwd
HESIOD(3) Library Functions Manual HESIOD(3)
NAME
hesiod_getpwnam, hesiod_getpwuid, hesiod_free_passwd - Hesiod functions for retrieving passwd information
SYNOPSIS
#include <hesiod.h>
struct passwd *hesiod_getpwnam(void *context, const char *name)
struct passwd *hesiod_getpwuid(void *context, uid_t uid)
void hesiod_free_passwd(void *context, struct passwd *pw)
cc file.c -lhesiod
DESCRIPTION
This family of functions allows you to retrieve passwd database information using Hesiod. To perform lookups, you need an initialized Hes-
iod context; see hesiod(3) for details. You may look up passwd information by name or by uid; information is returned in the same format
as by getpwnam or getpwuid. It is the caller's responsibility to call hesiod_free_passwd with the returned passwd entry to free the
resources used by the passwd entry.
Hesiod queries for passwd information are made using the ``passwd'' or ``uid'' Hesiod type, using either the username or the decimal repre-
sentation of the uid as the Hesiod name. The corresponding records should be a colon-separated list of fields giving the username,
encrypted password, uid, gid, GECOS information, home directory, and shell of the user.
RETURN VALUES
On failure, hesiod_getpwnam and hesiod_getpwuid return NULL and set the global variable errno to indicate the error.
ERRORS
These calls may fail for any of the reasons the routine hesiod_resolve may fail.
