Hi guys
I recently upgraded my mailserver from Ubuntu gutsy to hardy an
somehow SASL broke in the process:
I am using postfix with ldap for authentication and configuration. The
configuration part (aliases) works nicely, but when I try to submit to
port 587 which does an authentication via sasl/ldap I get:
mail.log shows this:

given that the new version of SASL works differently I have 2
instances running now, this is the one for postfix
root@collab:/etc/default# cat saslauthd-postfix

# Settings for saslauthd daemon
#
# Should saslauthd run automatically on startup? (default: no)

# Which authentication mechanisms should saslauthd use? (default: pam)
#
# Available options in this Debian package:
# getpwent -- use the getpwent() library function
# kerberos5 -- use Kerberos 5
# pam -- use PAM
# rimap -- use a remote IMAP server
# shadow -- use the local shadow password file
# sasldb -- use the local sasldb database file
# ldap -- use LDAP (configuration is in /etc/saslauthd.conf)
#
# Only one option may be used at a time. See the saslauthd man page
# for more information.

# Example: MECHANISMS="pam"
MECHANISMS="ldap"
# Additional options for this mechanism. (default: none)
# See the saslauthd man page for information about mech-specific options.

and to add insult to injury:
root@collab:# sudo -u postfix testsaslauthd -f

what am I missing?
this worked rather nicely before the upgrade from ubuntu gutsy to hardy
thanks
