sasl2 gentoo not working

[delay_2010]

Hi Forum,

I just instlaled ispCP 1.0.7 under gentoo. Everything is working except SMTP Auth when I want to send emails from my firefox.
I have generated SSL certificate successfully.

Using this /etc/sasl2/smtpd.conf:
pwcheck_method: auxprop
auxprop_plugin: sasldb
mech_list: PLAIN LOGIN CRAM-MD5 DIGEST-MD5

brings the same error as
/etc/sasl2/smtpd.conf:
mech_list: PLAIN LOGIN

the database exists: I even tried world readable but that does not help either.
ls -l /etc/sasl2/sasldb2
-rw-rw-rw- 1 root root 12288 Jan 10 19:49 /etc/sasl2/sasldb2

When I change e-mail password in ispcp, /etc/sasl2/sasldb2 gets updated. But that does not solve the problem.

I tried adding user manually via "saslpasswd2 -c anton" and password klaus.
But sasldblistusers2 lists:
anton@XXX: userPassword
no klaus is written. Only userPassword?!?

"testsaslauthd -u test -r XXX -p klaus" doesn't authenticate successfully, too.

So what I'm doing wrong?

Thanks,
Daniel
