- pppd: Implement option to strip domain part from MS CHAP response
- This patch implements a new boolean option "chapms-strip-domain" which
- strips the leading domain part of the username in a received MS Chap
- response.
- When the option is set, all leading chars up to and including the last
- backslash in the username are stripped. The option defaults to false.
- The patch originated from the Debian project.
