Password auth problem with openssh 3.4 and Linux 2.2.20

[Randy Tidd]

After upgrading to openssh-3.4p1, password authentication is no longer
working on my system.  I'm running Linux RedHat 6.2 with:

kernel 2.2.20
openssh-3.4p1
openssl-0.9.6
pam-0.72-6
pwdb-0.61-0

I've tried it with and without compression, with and without priv sep, and I
always get errors like this:

Jun 30 19:07:48 sugarfreejazz sshd[1344]: Failed password for randy from
10.10.10.2 port 4320 ssh2

It worked with openssh-2.9p2.  I upgraded because of the CERT advisory.
I've double, triple, and quadruple checked my userid, password, SSH client
(SecureCRT on Windows 2000), etc. and everything seems to be in order.

I did see this comment in the ChangeLog:

http://www.rpmfind.net//linux/RPM/PLD/dists/nest/test/i386/openssh-3.4p1-2.i
386.html

"Revision 1.125  2002/06/26 15:42:57  misiek
  - 3.4 (pam still not working)"

Is there a known problem with openssh 3.4 and PAM?

Also I tried compiling openssh without PAM by passing in the "--without-pam"
flag to configure but that did not seem to do anything -- "strings
/usr/local/sbin/sshd | grep pam" still reveals that it is compiled in.  Is
there a way to disable or compile without PAM?

Below is the output from sshd -d -d -d.  Thanks in advance for any
tips/info/advice.
