Help needed if anyone knows

[Riazansar]

dear members !

In my job i jst face this problem with one of our PHP based sites.

what this script does is that asks users for some inoformation when they want to have a folder in one of our web servers.
now the problem is that when they submit their information it gaves the user an ID that already is assigned to someone.
I am not a programer my job is networking and server managment soo if anyone knows the problem please let me know as soon as possible :)

here is the script

<?php
$host = "ldap1.unomaha.edu";
$base = "dc=unomaha,dc=edu";
$gbase = "ou=groups,$base";
$pbase = "ou=people,$base";
$log = "/var/log/groupman.log";
function stdin($ask)
{
print "$ask: ";
$stdin = fopen("php://stdin","r");
$answer = fgets($stdin,1024);
$answer = trim($answer);
if ($ask != "Your LDAP password")
{
$answer = strtolower($answer);
}
fclose($stdin);
if ($answer == 'q')
{
exit("Goodbye\n");
}
return $answer;
}
function pause()
{
print "\n";
$answer = stdin("Enter 'm' for menu, or 'q' to quit");
}
function notnull($ask)

do
{
$answer = stdin($ask);

Do you think your boss is ok with you posting this? Beside that, can't you trace the problem down to a specific piece fo code? This is to big for me to wade through.

To I like code that's indented.

[Riazansar]

it is not a project or soemthing like boss thing or etc....

i jst needed to figure the probelm in code out in order to move on with setting the server up. i am not a programer to narrow the code down but the problem is that the script gives users not a unique ID it gaves them the id that already is in use :)
