[Samba] password case sensitivity

[=?BIG5?B?qMy6v7/f?=]

Dear all,

    I have a problem regarding to password case sensitivity.

    Our company's servers are configured to use plain text passwords
with PAM due to historical reasons.  My collegues encountered a long
delay each time they boot their PC and map the network shared disks. 
They sometimes even failed connection.  The server always says:

Jul 18 17:54:37 atlas PAM_pwdb[30192]: authentication failure; (uid=0)
-> imacat for samba service

    or

Jul 18 17:59:52 atlas samba(pam_unix)[30197]: authentication failure;
logname= uid=0 euid=0 tty=samba ruser=
rhost=streetwalker.pristine.com.tw  user=imacat

    After several days of debugging, I found that the server had
received the password for 3 times: The client sent an upper-cased
version of the password and failed twice, and then the untouched password
(which is correct and successful).

    I guess it's the historical compatibility reason that Windows 98
does so.  I can try the "password level", though, but it can't fix the
delay (and maybe timeout) problem.

    Since it will send the untouched password at last, is there a way to
tell Windows 98 clients to send the untouched password first?  Is there
a possible way to modify some registry entries on this?  Or, should I
turn to encrypted passwords and make the hard way instead?

    I'm using samba 2.2.5 with linux 2.4.18, Red Hat 7.3, glibc 2.2.5,
pam 0.75, clients Windows 98 SE.
