saslpasswd2 and saslauthd restart

Hi all :-)

I've a sasl authentication (sasldb) that works good.

I discover that if I change the password of an user (with saslpasswd2),
using testsaslauthd, works fine. But when an email client try to send an
email, its can ONLY use old password (new and correct password is not
correct).

So, only after a restart of saslauthd daemon, I have to update password of
client email and whole system works fine.

Is this a bug or other thing?

I can't restart saslauthd using a production system :-/

Any idea?

thanks!

I use debian 7 with sasl2-bin version: 2.1.25.dfsg1-6+deb7u1
