passwd calls winbind unneccesarily



Hi,

ok i need help in writing a script which will affect the passwd program.

my problem is that i have implemented the single sign on.

now i wanted my windows users to be able to change there passwords from
linux boxes. so i changed the /etc/pam.d/passwd file. now it works fine
but the problem is that if i try to change the password of a local user it
prompts me twice for changing the NT password.

i want that some how the script should detect that the user is local and
pam_winbind.so doesnt need to be called . only pam_stack.so needs to be
called.


here is my /pam.d/passwd file


auth       sufficient   pam_winbind.so
auth       required     pam_stack.so service=system-auth use_first_pass

account    sufficient   pam_winbind.so
account    required     pam_stack.so service=system-auth

password   sufficient   pam_winbind.so
password   required     pam_stack.so service=system-auth


now what happens is that this works fine for a windows user. this is what
happens

[LINWIN/maryam niit158VM maryam]$ passwd
Changing password for user LINWIN/maryam
current) NT password:
Enter new NT password:
passwd: all authentication tokens updated successfully

now this is fine for a winodws user. password changed easily


now look at this for a local unix user.

[john niit158VM root]$ passwd
Changing password for user john.
Changing password for john
[B](current) NT password:[/B]
(current) UNIX password:
[B]Enter new NT password:[/B]
[B]Retype new NT password:[/B]
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

THE BOLD LINES are where the problem is. even if the user is a local unix
user the system still asks to change the NT password? although at the end
the local user's password is changed but still i dont want this extra
messages coming up?

how to get out of this?
