Description of problem:
I have set the smb.conf to be able to access the /etc/passwd file to 
update the unix password when the user changes the smb password with 
the smbpasswd tool.  The smb.conf has the following:

#These have been uncommented

  encrypt passwords = yes
  smb passwd file = /etc/samba/smbpasswd
  unix password sync = Yes
  passwd program = /usr/bin/passwd %u
  passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %
n\n *passwd
:*all*authentication*tokens*updated*successfully*
  passwd chat debug = yes
  username map = /etc/samba/smbusers


Version-Release number of selected component (if applicable):
samba-3.0.2-6.3E 
samba-common-3.0.2-6.3E
samba-client-3.0.2-6.3E
kernel-2.4.21-9.0.1.EL

How reproducible:

Every Time

Steps to Reproduce:

1. The following have been uncommented in the /etc/samba/smb.conf 
file:

  encrypt passwords = yes
  smb passwd file = /etc/samba/smbpasswd
  unix password sync = Yes
  passwd program = /usr/bin/passwd %u
  passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %
n\n *passwd
:*all*authentication*tokens*updated*successfully*
  passwd chat debug = yes
  username map = /etc/samba/smbusers

2. I have added a user "user1" and given a password of "user1".   
     useradd user1; passwd user1

3. Start the smb services
     service smb start; chkconfig smb on

4. Add the smb user "user1" with password "user1"
     smbpasswd -a user1

5. Add the user to the /etc/samba/smbusers
     echo "user1 = user1" >> /etc/samba/smbusers

6. Log in as user

7. Change password with smbpasswd
    

  
Actual results:

Old SMB password:
New SMB password:
Retype new SMB password:

Error connecting to 127.0.0.1 (Connection timed out)
unable to connect to SMB server on machine 127.0.0.1. Error was : 
SUCCESS - 0.
Failed to change password for user1

Expected results:

The smbpasswd command should have changed the smb password and the 
unix password.

Additional info:

There is no relevent infomation in the log files, I added the "passwd 
chat debug = yes" option and did not find that it increased logging 
very much.
