password change problem

[Todd Pfaff]

I posted my original question below to the samba-ntdom list but it seems
to be the wrong place to be discussing this problem so I'm moving my
follow-up to these lists.

Background...I used to be using smbpasswd and the "unix password sync",
"password chat", and "password program" settings to keep my smb passwords
and unix passwords in sync.  This was working well in an earlier release
of 1.9.18 but one of the messages below indicates that this broke in
1.9.18p10.  I didn't notice it was broken until recently when I started
using 2.0.0beta1 and so I thought that it was broken only in the 2.0.0
samba domain control code.

Yes.  In fact, the unix password change is working fine but then the smb
password change fails, which means my unix and smb passwords are getting
out of sync, which is what "unix password sync" is supposed to avoid.

Only the standard Solaris 2.5 password defaults which impose a minimum
password limit of 6 characters.  But this isn't the problem since, as I
said, the unix password change (via the password chat) is working fine.

Thanks for the replies.
