Hello,
I have installed Exim4 on my Debian Wheezy. All is running fine.
Now I try to use "fixed_cram" authenticator for more security.
/etc/exim4/conf.d/auth/20_vexim_server_auth looks like:
#plain_login:
# driver = plaintext
# public_name = PLAIN
## server_condition = ${lookup pgsql{AUTH_PLAIN_LOOKUP} {yes}{no}}
# server_condition = ${lookup pgsql{AUTH_PLAIN_LOOKUP} {yes} \
# {${if
crypteq{$3}{${extract{1}{:}{${lookup{$2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}
{yes}{no}}}}
#
# server_set_id = $2
fixed_login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
# server_condition = ${lookup pgsql{AUTH_LOGIN_LOOKUP} {yes}{no}}
server_condition = ${lookup pgsql{AUTH_LOGIN_LOOKUP} {yes} \
{${if
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{yes}{no}}}}
server_set_id = $1
fixed_cram:
driver = cram_md5
public_name = CRAM-MD5
server_condition = ${lookup pgsql{AUTH_LOGIN_LOOKUP} {yes} \
{${if
crypteq{$2}{${extract{1}{:}{${lookup{$1}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{yes}{no}}}}
server_set_id = $1
a test connection:
telnet myserver.de 25
Trying 1.1.1.11...
Connected to myserver.de.
Escape character is '^]'.

quit
Connection closed by foreign host.
When I comment out the fixed_login part so that only fixed_cram is
active I get the following "error result":
2014-01-21 11:19:59 H=p578a6f5e.dip0.t-ipconnect.de ([192.1.1.1])
[1.1.1.1] F=<ba...@myserver.de> rejected RCPT <bas...@arcor.de>: relay
not permitted
I think there is something wrong with the login or the database query.
The auth querys are:
AUTH_PLAIN_LOOKUP = SELECT '1' FROM eximusers WHERE
username='${quote_pgsql:$2}' AND clear='${quote_pgsql:$3}'
AUTH_LOGIN_LOOKUP = SELECT '1' FROM eximusers WHERE
username='${quote_pgsql:$1}' AND clear='${quote_pgsql:$2}'
AUTH_CRAM_LOOKUP = SELECT clear FROM eximusers WHERE
username='${quote_pgsql:$1}'
The user Table looks like:
CREATE TABLE eximusers (
user_id serial NOT NULL,
domain_id integer NOT NULL,
localpart character varying(192) NOT NULL,
username character varying(255) NOT NULL,
clear character varying(255),

CONSTRAINT users_gid CHECK (((uid >= 1) AND (uid <= 65535))),
CONSTRAINT users_maxmsgsize CHECK ((maxmsgsize > -1)),
CONSTRAINT users_type CHECK ((((((((("type")::text = 'local'::text)
OR (("type")::text = 'alias'::text)) OR (("type")::text =
'catch'::text)) OR (("type")::text = 'fail'::text)) OR (("type")::text =
'piped'::text)) OR (("type")::text = 'admin'::text)) OR (("type")::text
= 'site'::text))),
CONSTRAINT users_uid CHECK (((uid >= 1) AND (uid <= 65535)))
);
How can I debug the exim-auth process?
Thanks for any help.
Regards,
Basti
