Default SMPT AUTH problem

Hi, i have a problem with sendmail and saslv2 authentication,
i have configured sendmail to permit relay to authenticated users
but with right login and password it don't authenticate.
If i try testsaslauthd it work fine and test is ok but when i try
to authenticate via sendmail it don't authenticate me.
This is some information about:
sendmail config:

Most important, what messages are being logged?

Be sure to turn on logging for the highest level, if you don't get
useful leads at first.

Ok i have passed to an high log level sendmail and the problem that
give me is Login Failed i have also undestood where is the problem.
On my server some users are created so user.domain and the
authentication for this user work fine, other users created as
user@domain don't work because sendmail see @domain as realm but

the real user are user@domain and not just user.
Any idea to resolve?

I have set up auth on Debian, where I run postfix, so it's not directly
comparable.


My users who don't specify a domain are check against the default domain
name which is the name postfix gives in its greeting.


The difficulty I had was discovering what domain it was using, testing
is all very well, but it's useless testing something that's not what is
being done.

Hi John i have resolved, i search on many many how too and found many
exsotic solutions than i have found a little how too where i see that
into the start parameter of salsauth into /etc/init.d there was a -r and
this -r used to indicate that the username can have @ into its name and

now work with and without @.
