[nflug] samba woes

[Richard Hubbard]

The reason why this is important is this:
Samba has a 'password sync' that tries to keep *nix an Samba passwords the same.  When someone is working in windows, and uses Windows tools to change passwords (ctrl-alt-del, change password), then when this is sent to the Samba server, samba will take the password and run a script to change the linux password.  
When you change a linux password, there is no background process that knows that it has to contact Samba and change that password.

First recommendation, use a centralized login.  Being the geek I am, I would recommend configuring one of your Samba boxes as a Windows Primary Domain Controller.  Make the windows machines, and all other samba boxes as member servers/members of the domain.  Set up Winbindd and pam, to get all authentication from the pdc first, then go local if the pdc isn't available.

This will probably take care of 90% of your password problems.

You are still not saying HOW YOUR ARE CHANGING your password 
saying "webmin" tells me nothing as I donno what that is doing.

If you use "passwd" from an intereactive session, this won't  do
anything for samba,  you'd ALSO need to change the password in
samba via smbpasswd.  If you are changing the passwod from a
windows client  the unix side will ONLY be changed if you have
passwd sync and passwd chat PROPERLY setup.  read the smb.conf man
page and read up on passwd chat, and enable debugging to see where
it is failing...
