Hi,
I'm writing a program where I need to validate a users password.
Right now I'm using crypt and code like the following:
pentry is a pointer to a passwd struct obtained by using the users
userid.
err is in a int initialized to 0;
userpass is a c string containing the users plaintext password.
if ( pentry == NULL ) {
perror("I couldn't get your encrypted password.");
return err;
}
salt[0] = pentry->pw_passwd[0];
salt[1] = pentry->pw_passwd[1];
salt[2] = '\0';
usercrypt = crypt(userpass, salt);
if ((err = strcmp(usercrypt, pentry->pw_passwd)) == 0) {
the strcmp always returns unsuccessful even though I know the passwd I
put in when I try it is correct. Is there something funky I have to do b/c
I'm using shadow passwd's and pam? The pw_passwd shows up in the debugger
as "x" instead of the encrypted version of the passwd.
I could use another set of eyeballs :)
Thanks.
