saslauthd : Permission denied after todays dist-upgrade

[Bengt Thure'e <bengt@zag.att.ne.jp>]

Hej

I did a apt-get dist-upgrade on my mail server this evening on my 
mailserver which is based upon Sarge.

After this postfix can not connect to the saslauthd daemon anymore.
Has anyone else encountered the same problem?

I checked the /var/cache/apt/archives directory for the latest installed 
packages:
mollie:/var/cache/apt/archives# ls -lart | tail
417982 Jun 11 08:45 nano_1.2.3-2_i386.deb
983520 Jun 12 11:21 libsnmp-base_5.1.1-2_all.deb
548116 Jun 12 11:22 fetchmail_6.2.5-8_i386.deb
150058 Jun 15 23:42 libsasl2-modules_2.1.18-4.1_i386.deb
110056 Jun 15 23:42 sasl2-bin_2.1.18-4.1_i386.deb
135794 Jun 15 23:42 libcyrus-imap-perl21_2.1.16-6_i386.deb

I did a dpkg -i libsasl2 sasl2 libcyrus to the earlier version, but this 
did not help.

In the end I went back to the latest Sarge by doing another dist-upgrade.

Do anyone have any suggestions or advice on this issue?
I can send e-mails by using squirrelmail, but I need the saslauth to 
confirm all users who wants to send by their e-mail clients.

Thanks in advance

I have postfix in chroot, and I also have two postfix queues with 
mailscanner in between.
