| 1 | pppd: Implement option to strip domain part from MS CHAP response |
| 2 | |
| 3 | This patch implements a new boolean option "chapms-strip-domain" which |
| 4 | strips the leading domain part of the username in a received MS Chap |
| 5 | response. |
| 6 | |
| 7 | When the option is set, all leading chars up to and including the last |
| 8 | backslash in the username are stripped. The option defaults to false. |
| 9 | |
| 10 | The patch originated from the Debian project. |
