synchronize samba(ldap)/unix

[Diplomandenkomitee M94]

Hi Svante,

thanks for the instant help about the synch of ldap and samba.
I tried your hints, but didn't succeed :(
When I turn the unix password synch on the users can't change their
passwords (neither with smbpasswd nor via Win-NT).
I looked in the logs and found the following error:

[1999/09/21 20:13:04, 3] smbd/chgpasswd.c:chgpasswd(383)
  Password change for user: spring
[1999/09/21 20:13:04, 3] smbd/chgpasswd.c:chat_with_program(310)
  Cannot Allocate pty for password change: spring

the smbpasswd program stops with the error:

machine 127.0.0.1 rejected the password change: Error was : The
specified password is invalid.
Failed to change password for spring

I have looked in the logs of my ldap server and found out that there was
no trial to change the passwd on the server.

Do you have any idea what the problem could be ?
It would be great if you could give me a hint.

Thanks in advance!
