Hello *,

sorry to bother you again with this topic.
Last time Ralf helped me to get it running, this time I'm configuring a backup mailserver
using almost the same setup (difference SuSE8.1 and TLS/SSL patch) and got an error
I haven't encounterd before (Thanks for Murphy's Law):

Setup:
=====
postfix2.0.3 (patched with TLS/SSL)
sasl2-2.1.10

Short problem description:
===================
Feb 4 12:57:13 email postfix/smtpd[23389]: warning: SASL authentication failure: All-whitespace username.

Long problem description with setup:
===========================
As for sasl2 - the saslauthd is up checking against /etc/shadow (option -a shadow)
The postfix user can read /etc/shadow by group permissions.

The delivered test-programm testsaslauthd -u username -p password
succeded. So i assume sasl should be ok so far.

As for Postfix:
/usr/lib/sasl2/smtpd.conf has
pwcheck_method: saslauthd
mech_list: plain

/etc/postfix/main.cf contains
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_sasl_auth_enable = yes

telnet localhost 25 seems also ok
220 email.itec-koeln.de ESMTP Postfix on SuSE Linux 8.1 (i386)
EHLO x.y.
250-email.itec-koeln.de
250-PIPELINING
250-SIZE 70000000
250-ETRN
250-AUTH PLAIN
250-AUTH=PLAIN
250 8BITMIME

However when I'm trying to test the smpt auth (with Eudora52) the logfile shows:

Feb 4 12:57:12 email postfix/smtpd[23389]: connect from unknown[192.168.1.57]
Feb 4 12:57:13 email postfix/smtpd[23389]: warning: SASL authentication failure: All-whitespace username.
Feb 4 12:57:13 email postfix/smtpd[23389]: warning: unknown[192.168.1.57]: SASL PLAIN authentication failed

Does anyone had this before? Honestley I'm running out of ideas...

Cheers,

Stefan
