[Samba] Different shells

[Nir B]

Hi All,

I added Linux machines to my AD domain (Windows 2000 native domain) and have 
the following problems / questions:

1 - How can I set the shell per user? (I know how to set per computer on the 
smb.conf  "template shell = /bin/sh", I have few users that work on the same 
machine and use different shells)

2 - I noticed that if you logon as root, you can do SU to each user on the 
Active Directory, without providing password. How can block this or force to 
provide the user password?

Thanks In Advanced!
