Cannot change password

[Peter Debus]

Server: Slakware Linux 2.0.30, GNU C 2.7.2.1 Samba 18p7

Server is not using PAM and is a ypclient.

Client PC's are DOS 6.20 with MS Client 3.0 and Windows 95.


I am having trouble changing passwords using the "net password \\<server>"
command from either DOS or Win95 command prompt. Changing passwords worked fine
using Samba 17p3.

The compile switch -DALLOW_CHANGE_PASSWORD has been used and smb.conf
parameters are set up correctly.

[global]
 passwd program = /usr/bin/yppasswd
 passwd chat = "*Old password*" %o\n "*New password*" %n\n "*ype new password*
" %n\n *changed*
 password level = 4

The error reported in the client log file at log level 4 is:

Doing SetUserPassword
Set password for <PDEBUS>
SMB Password - pwlen = 7, challenge_done = 0
Checking password for user pdebus (l=7)

Changing the Unix password failed at "Dochild for user pdebus", but note
the uid, it is 0 not pdebus' uid. Calling yppasswd as root will attempt to 
change root's password, not pdebus'. 

Does anyone have a suggestion. I have removed the password level option
in smb.conf and toyed with all upper and lower case passwords, but the
problem persists. I am not using encrypted passwords, hence the password change
fails on "get_smbpwd_entry" and "check_lanman_password".
