Installing user management system

I have a website and want to add a user management system. I downloaded quite a few of them and installed on my server, but most of them need debbuging or are not quite working.
I am looking for something that has:
1.user registration
2.email activation
3.login/logout
4. recover password if user forgot the password

Or if anyone knows a good tutorial it would be a help too.

Have you tried Meunity Community System (http://meunity.sourceforge.net)?

i just tried it and i get this continuous error when i try to open the index page.

Warning: feof(): supplied argument is not a valid stream resource in c:inetpubwwwrootmeunitymeunitytemplate.php on line 48

Warning: fgets(): supplied argument is not a valid stream resource in c:inetpubwwwrootmeunitymeunitytemplate.php on line 49

I get this message when i try to run /meunity/public/index.php

I am using IIS 5.0 , PHP 4.3 , and Mysql.
I need some help fixing this!

What does your configuration file look like?

are you talking about php.ini

ok i finally found a good user system called patUser and it looks good and all but im having trouble installing it or i get some errors, could be my php config file, but cant figure it out, i tried changing things but still nothing. It looks to me that sessions are not configured correctly. here are some errors that i get.

Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

I changed session.save path to C:windowstemp but it dont work for some reason.

Help please!

You need to create a tmp directory in c: it should work then unless you have other setup promblems but this will solve the errors you have listed.
