Changing Unix password

[mah6430]

First off, I am not a c programmer, but I'm tasked with finding if something is even possible.

We have an application that prompts a user for password on login. There is backend c code that validates this password against the user's unix password.

Unfortunately, we now need the capability to allow the user to change their password from the application. The user's do not currently have telnet capability.

Can a c program be written that would allow this application to modify the unix password - if so, any ideas on where I can crib some code?

Thanks in advance,
Michael

did you ask in the c/c++ forum? I know that can be possible, I don't know how, but I guess you can have something like the "system(password user)" command, to call a OS command from the C program.

cheers.

I don't know C programming, but to get over the passwd permissions problem, you could implement sudo
