From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 95) Description of problem: The passwd.c indicates that this is by design error: passwd.c:L373 i = read(STDIN_FILENO, newPassword, sizeof(newPassword) - 1); newPassword[i - 1] = '\0'; I can assume this was done to strip line feed character when reading password from one-string files. This is not a correct behaviour. It's a user responsibility to supply just the data the user wants. For compatibility reasons you may correct this error by introducing new option like '--not-strip'. When this option applied, passwd should not strip the last character. Version-Release number of selected component (if applicable): passwd-0.67-3 How reproducible: Always Steps to Reproduce: 1. Execute in bash: echo -n boguspas | passwd --stdin someuser 2. Try to login as 'someuser' Actual Results: Can't login with 'boguspas', but can login with 'boguspa' password. Expected Results: Login with 'boguspas' password.
