password changing not working

[Harald H. Hannelius]

Hi, somewhere along the versions password changing stopped functioning.
I am running 2.1-prealpha from 24 May 1999. I always get the same error
when I am trying to change my password with smbpasswd:

[1C0] 1E 91 FA D7 60 2B EC 5C  AD AE 74 B7 36 A1 B0 93  
....`+.\ ..t.6...

..Z.ew.. .Er..pk.
write_socket(3,635)
write_socket(3,635) wrote 635
receive_smb: length < 0!
client_receive_smb failed

smbpasswd exits without any visible error to the user, but the password
never gets changed. I get this in the logfile every time:

(Yes, my password string is changed to protect the innocent :)

Here's the relevant parts of my smb.conf:

        unix password sync = yes 
        passwd program = /usr/bin/passwd %u ; /root/Scripts/yp-restart
        passwd chat = *word: %n\n *word: %n\n *changed*
        passwd chat debug = true

The trick with a semi-colon after /usr/bin/passwd %u has worked, the NIS
map has always been updated. There's no difference in the error message if
i move the yp-restart call away from the line.

Also, I have changed include/rpc_samr.h MAX_SAM_ENTRIES to 1000, because
we have about 800 users here. I'm not shure whether that affects the
passwd change. I tried with default 250, no avail.

Please help me, I cannot find a workaround for this, and it is very
important that users can change their passwords.
