When turning on logging this displays as a warning where both challenge responses are shown, and seem equal except for the case. >How-To-Repeat: One needs a Watchguard (or perhaps Linux) firewall and build the pptpclient configuration and connect with a pptp-enabled usercode >Fix: In /usr/src/usr.sbin/ppp/chap.c:line 905 insert a conversion for both answers to either upper or lowercase, and then compare. This fixes the problem and a working connection is than build. Not shure if the case conversion should take place somewhere else >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
