I don't get it. Why must the UID be in /var/smb/passwd? Is it an
optimization? Or are both, name and UID stored in there to help detect
user renames and renumberings? If the former, that seems wrong. If the
latter, then it didn't work :)
I think the latter would be commendable, if it worked. I think it could
work:
pw = getpwnam_r(cifs_username, &pwd, pwbuf, sizeof (pwbuf));
if (pw == NULL) {
/* not found *
...
} else {
smbpw = lookup_smb_pwbyname(pw->pw_name);
if (smbpw->uid != pw->pw_uid) {
/* Stale entry found */
...
} else {
/* Found a /var/smb/passwd entry */
...
}
}
