Hello Corona688,
I have both RHEL6.5 and RHEL7.5 and they behave the same. I've not thought about testing it on our couple Ubuntu servers but the need never comes up. The number that we're using as the login ID are employee numbers affectionately known as WorkDay ID's assigned by the AD group. We're using them so the NAS filers play nice with the Linux user when accessing mixed filesystems with permissions controlled by Windows. We were basically forced to since the storage group didn't want to maintain a Linux user name to WorkDay ID map. As for the UID I'm simply incrementing to the next available number. It never dawned on me when this took place that ps would interpret the numeric login ID as the UID. I have to assume that's what's happening. I may end up having to create an alias much like the code you suggested.

posix_getpwnam
POSIX_GETPWNAM(3) 1 POSIX_GETPWNAM(3)
posix_getpwnam - Return info about a user by username
SYNOPSIS
array posix_getpwnam (string $username)
DESCRIPTION
Returns an array of information about the given user.
PARAMETERS
o $username
- An alphanumeric username.
RETURN VALUES
On success an array with the following elements is returned, else FALSE is returned:
The user information array
+--------+---------------------------------------------------+
|Element | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| name | |
| | |
| | The name element contains the username of the |
| | user. This is a short, usually less than 16 char- |
| | acter "handle" of the user, not the real, full |
| | name. This should be the same as the $username |
| | parameter used when calling the function, and |
| | hence redundant. |
| | |
|passwd | |
| | |
| | The passwd element contains the user's password |
| | in an encrypted format. Often, for example on a |
| | system employing "shadow" passwords, an asterisk |
| | is returned instead. |
| | |
| uid | |
| | |
| | User ID of the user in numeric form. |
| | |
| gid | |
| | |
| | The group ID of the user. Use the function |
| | posix_getgrgid(3) to resolve the group name and a |
| | list of its members. |
| | |
| gecos | |
| | |
| | GECOS is an obsolete term that refers to the |
| | finger information field on a Honeywell batch |
| | processing system. The field, however, lives on, |
| | and its contents have been formalized by POSIX. |
| | The field contains a comma separated list con- |
| | taining the user's full name, office phone, |
| | office number, and home phone number. On most |
| | systems, only the user's full name is available. |
| | |
| dir | |
| | |
| | This element contains the absolute path to the |
| | home directory of the user. |
| | |
| shell | |
| | |
| | The shell element contains the absolute path to |
| | the executable of the user's default shell. |
| | |
+--------+---------------------------------------------------+
EXAMPLES
Example #1
Example use of posix_getpwnam(3)
<?php
$userinfo = posix_getpwnam("tom");
print_r($userinfo);
?>
The above example will output something similar to:
Array
(
[name] => tom
[passwd] => x
[uid] => 10000
[gid] => 42
[gecos] => "tom,,,"
[dir] => "/home/tom"
[shell] => "/bin/bash"
)
