Hello,
I'm in the process of migrating user accounts from Digital Unix system
to Linux with MySQL database holding users' data and Exim 4.10.
I've found, that some passwords of DUX's users have a strange form, e.g.:
"qzgyNslr3WpesDi.7XrD9rx6". AFAIK, those passwords are created with crypt16()
system function, which is used on DUX, when user enters a password longer
than 8 characters.
After copying such a password to the new system, the user can log on
without any problem (SSH/POP3/IMAP authentication is done via nss-mysql
and PAM), but he/she can't use SMTP AUTH capability of Exim.
My configuration:
auth_plain:
driver = plaintext
public_name = PLAIN
server_condition = "${if and { {!eq{$2}{}} {!eq{$3}{}} \
{crypteq{$3}{${lookup mysql{SELECT password FROM user WHERE user_name='$2'} \
{$value}fail}}}}{1}{0}}"
server_set_id = $2
client_send = CLIENTAUTHPLAIN
(auth_login is very similar).
Apparently crypteq doesn't recognize those passwords, and the authentication
fails because of "wrong password" (and I'm sure a good password was entered).
Any suggestion about how to deal with the problem?
