Hi all! Maybe this question is not 100% about Postfix, but it is related. I am configuring a Postifx server with SASL authentication.
When I do a test to authenticate, I get an error: ------------------------------------------------------------------ root@server2:~# saslpasswd2 -c daniel ------------------------------------------------------------------ root@server2:~# testsaslauthd -u daniel -p password 0: NO "authentication failed" ------------------------------------------------------------------ However it works when I provide the realm: ------------------------------------------------------------------ root@server2:~# testsaslauthd -u daniel -r server2 -p password 0: OK "Success." ------------------------------------------------------------------ It's strange because I have another mail server where it works without problems: ------------------------------------------------------------------ root@mail:~# testsaslauthd -u daniel -p password 0: OK "Success." ------------------------------------------------------------------ Both hosts have Debian Jessie and the SASL configuration is the same: ------------------------------------------------------------------ root@mail:~# grep ^[^#] /etc/default/saslauthd START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="sasldb" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/run/saslauthd" ------------------------------------------------------------------ root@server2:~# grep ^[^#] /etc/default/saslauthd START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="sasldb" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/run/saslauthd" ------------------------------------------------------------------ "mail" has some updates to apply, but I do not see any differences in the versions of the SASL packages: ------------------------------------------------------------------ root@mail:~# aptitude show libsasl2-2 | grep Versión Versión: 2.1.26.dfsg1-13+deb8u1 root@mail:~# aptitude show libsasl2-modules | grep Versión Versión: 2.1.26.dfsg1-13+deb8u1 root@mail:~# aptitude show sasl2-bin | grep Versión Versión: 2.1.26.dfsg1-13+deb8u1 ------------------------------------------------------------------ ------------------------------------------------------------------ root@server2:~# aptitude show libsasl2-2 | grep Version Version: 2.1.26.dfsg1-13+deb8u1 root@server2:~# aptitude show libsasl2-modules | grep Version Version: 2.1.26.dfsg1-13+deb8u1 root@server2:~# aptitude show sasl2-bin | grep Version Version: 2.1.26.dfsg1-13+deb8u1 ------------------------------------------------------------------ In this case I'm not doing the authentication test against IMAP but directly against SASL, so I guess the problem will be directly related to the SASL configuration itself. In case it is useful, when the authentication fails I get this in /var/log/auth.log: ------------------------------------------------------------------ May 24 15:31:38 server2 saslauthd[2701]: do_auth : auth failure: [user=daniel] [service=imap] [realm=] [mech=sasldb] [reason=Unknown] ------------------------------------------------------------------ It seems that authentication is done through IMAP and I have previously installed the Cyrus packages. Any thoughts about what might differ between the two environments? Thanks in advance. Kind regards, Daniel
