Hi experts.

I have a linux redhat server with sendmail. All Mail account users are added as system users.

I want to write a php program that let users change their mail passwords (or system passwords) but i don't know how to do it because this is handled via passwd and shadow files.

My question is, is there any way to do it with php or should i try something else??.

The goal is the users can modify their own passwords (for mail account purposes).

Thanks.

Hi rbraym,
Personally I would install Squirrelmail which is a webmail system. You can then install the plugin which enables users to change their password.

You can write something yourself in PHP and if you know PHP it wont be difficult. Why do you want to write it yourself instead of installing a webmail program such as Squirrelmail which also has a module for you to change your password?
Squirrelmail will just give you an alternative metod of accessing your mail. Sometime this is usefull if people are using a different machine and don't want to have to setup the email client.

the access rights might be the problem. Becouse most of opensource webmail are balanced in case of functionality and security. Thats why I (and not only I)was pointing to some kind of webmail.
a) as grblades mentioned above - it might be usefull
b) as I mentioned above - You can use module to implement in your site

From the other hand if You will not try to analyze changing password module You will not learn anything.
The choice is up to You
