hi there,
I wonder is anyone know how can I check if a given password is valid for a specified user. So far, I can find out if a given user exits by searhing the corresponding name in /etc/passwd, however, how can I check if the given password is also valid?
Distribution: Solaris 11.4, Oracle Linux, Mint, Debian/WSL

Rep:
Yes, log in as the user with the given password, and see if it succeeds. By the way, are you trying to build a program to crack passwords ?

I think it's just an attempt to use system passwords in a program, as it is done in many cases. Here's a HOWTO that will be useful (check especially chapter 8): http://www.ibiblio.org/pub/Linux/doc...Password-HOWTO
