Postfix - SMTP - authentication failed

[Hans]

I use my Postfix smtp-server for outgoing email.

Since today; when i send an email using my emailclient and this Postfix SMTP-server, an error occurs:

Authentication failed:
The username and/or password is not permitted.

I also discovered that i can not start the saslauthd daemon:
/etc/init.d/saslauthd start

When i do an /etc/init.d/saslauthd start

I receive this message:
Starting SASL Authentication Daemon: (failed).

What can be wrong?

I hope someone knows.

I thought that i solved the problem.
But the problem still remains.

When i kill all processes as mentioned in Falko's solution,
saslauthd is is starting up indeed, but when i give the command:

/etc/init.d/saslauthd restart

The system responds:

Stopping SASL Authentication Daemon: (not running).
Starting SASL Authentication Daemon: (failed).

So, my conclusion is: saslauthd is not running at all and maybe it also explains a bit my problem with authentication using smtp, as descibed in thread called "Can not receive e-mail - Postfix" from yesterday.

I do not know what to do now,

Some support would be great!
