| Subject: | [PATCH] Provide a reason for authentication failure back to the user |
Hi, I emailed this and one other patch to the maintainer a few days ago
and have not heard a response, so I thought I would post the patches
here as well.
I've also added some documentation to this patch.
####################################
# Give a reason when rejecting login
This patch allows the authentication_hook to return a string which will be
presented to the user describing why their login was rejected.
