Hello!
I'm using exim 4.12 .
I configured authenticators like:
---------------------------------------
begin authenticators
login:
driver = plaintext
public_name = LOGIN
server_prompts = Username:: : Password::
hide server_condition = ${if eq{$2}{PASSWORD_LOOKUP}{yes}{no}}
server_set_id = $1
---------------------------------------
If PASSWORD_LOOKUP doesn't end with "fail", it accepts
empty passwords for unknown accounts.
If PASSWORD_LOOKUP ends with "fail" I get the following
reply from exim in SMTP session:
--------------------------------------
AUTH login
334 VXNlcm5hbWU6
aHJicmZy
334 UGFzc3dvcmQ6
435 Unable to authenticate at present
--------------------------------------
But how could I get the proper "535 Incorrect authentication
data" ? If I check for empty passwords within server_condition, I deny
such passwords at all. It seems to be not very good.
Any ideas? Is there a way to distinguish between "not
found" lookup result, and "lookup failed" (server error for example)?
Bye. Alex.
