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.
