[sqwebmail] Strange behavior in sqwebmail?

[tomd]

Hello folks,

I am building a new server and have what seems a very odd problem: For
some reason, only postmaster can log into sqwebmail in all virtual
domains. All other users are refused authentication.
Here is the setup:
RH 6.2 2.2.22-6.2.2 (Yeah, I know but can't get 8.0 to run on this Intel)
Apache 1.3.22
qmail 1.03
ucspi-tcp 0.88
vpopmail 5.2.1
sqwebmail 3.4.0
All of the RedHat updates have been applied.
sqwebmail was configured:
./configure --without-authpam --without-authuserdb --enable-webpass=no\
--without-authpwd --without-authshadow -enable-default-domain=big.com
The domain "big.com" has approx. 600 e-mail users and so I wanted to add
convenience for the greatest numbers. There are a half dozen other
virtual domains on this server as well.
Everyone can log into big.com through sqwebmail with either just username
or [EMAIL PROTECTED]
Everyone can log into anywhere through POP3 using [EMAIL PROTECTED]
No one except postmaster (???!!!) can log into domains other than big.com
through sqwebmail. I have tried deleting and recreating accounts, deleting
vpasswd.cdb, deleting and recreating domains all to no avail.
Does this make any sense to anyone out there? I have used an older version
of sqwebmail on a different machine for years with no problems. This new
setup is very similar to the old machine but with older software.
All clues welcomed!
