samba - May 1998 - Samba 1.9.18p7 Password Lock Problem on AIX 4.1.4.0

I've been running SAMBA 1.9.14 and 1.9.17p4 for successfully for some
time.  Recently I thought it would be useful to update to the latest
SAMBA version 1.9.18p7.  This is the first time we are using Samba with
the built-in DES.

Here is our configuration:
Machines:    IBM RS/6000 AIX 4.1.4.0 or AIX 4.2.1.0
Compiler:    xlC 3.1.4.0

My smb.conf file:
[global]
   printing = aix
   print command = /usr/local/etc/samba/bin/print %p %s
   lpq command = /usr/bin/lpq -P%p
   printer name  = qms
   printcap name = /usr/local/etc/samba/printcap
   lpq cache time = 20
   guest account = samba
   browseable = yes
   printable = no
   public = no
   writeable = no
   client code page = 437
   encrypt passwords = yes
   security = user
   status = yes
   dead time = 30
   read prediction = True
   socket options = TCP_NODELAY
   preserve case = yes
   short preserve case = yes
   wins server = xxxx.xxx.xxx
   hosts allow = xxx.xxx
   remote announce = xxx.xxx.xxx.xxx/aaa yyy.yyy.yyy.yyy/bbb
zzz.zzz.zzz.zzz/ccc

;   debug level = 3

[homes]
   comment = Home Directories
   include = /usr/local/etc/samba/lib/home.%M
   browseable = no
   writeable = yes
   create mode = 0755
   dont descend = /unixhome/ntwin,./unixhome/ntwin

[printers]
   comment = All Printers
   path = /usr/spool/samba
   browseable = no
   printable = yes
   create mode = 0700

And I get the following error message in "log.smb" file when I attempt
to connect to my home share:

do_pw_lock: failed to lock SMB passwd file.
get_smbpwd_entry: unable to lock file /export1/samba/private/smbpasswd
NT Password did not match ! Defaulting to Lanman
do_pw_lock: failed to lock SMB passwd file.
get_smbpwd_entry: unable to lock file /export1/samba/private/smbpasswd
do_pw_lock: failed to lock SMB passwd file.
get_smbpwd_entry: unable to lock file /export1/samba/private/smbpasswd
NT Password did not match ! Defaulting to Lanman
...

Any help would be much appreciated.

Thanks, Richard Hogue
