Summary0018328: htpasswd from httpd-tools rejects password longer than 255 characters
DescriptionThe manpage for htpasswd implies that for Linux, there is supposed to be no limitation on password length. But when I give it a password longer than 255 characters, I get an error. Either something is wrong in the build, or the manpage should be adjusted.
Steps To Reproduce$ sudo yum -q install httpd-tools
Package httpd-tools-2.4.6-97.el7.centos.x86_64 already installed and latest version
$ dd if=/dev/zero bs=1 count=255 2>/dev/null | htpasswd -nsi someuser

$ dd if=/dev/zero bs=1 count=256 2>/dev/null | htpasswd -nsi someuser
htpasswd: password too long (>255)

I confirm that your findings are correct. However this is a problem that can be fixed in Centos if and only if RHEL ships an updated version which corrects it. You could file a bug report at but since EL7 is in maintenance mode, RedHat accepts mostly security related bug reports and will most certainly do not do anything.
