[Samba] Classic upgrade and forced password change...

I'm doing some test moving from a NT domain to ad AD domain, using
debian jessie samba (4.2) and obviously the 'classicupgrade' procedure.

In my setup i use(d) extensively some script to reset password to
users. I was (ab)used to have 'smbpasswd' behave differently if
executed by root, eg change the password without taking in
consideration password policy and check password scripts.

This seems not the case for AD mode (using 'gaio' as password):

 root at lupus:~# smbpasswd gaio
 New SMB password:
 Retype new SMB password:
 Failed to modify account record
CN=gaio,CN=Users,DC=ad,DC=corsi,DC=sv,DC=lnf,DC=it to set user attributes:
0000052D: Constraint violation - check_password_restrictions: the password is
too short. It should be equal or longer than 8 characters!
 Failed to modify entry for user gaio.

 root at lupus:~# samba-tool user setpassword gaio
 New Password: 
 ERROR: Failed to set password for user 'gaio': (19, '0000052D:
Constraint violation - check_password_restrictions: the password is too short.
It should be equal or longer than 8 characters!')

This is ''intended'', or is a bug of samba 4.2 version?


There's some way to circumvent it?


Thanks.

You will probably be better off using a later version of Samba, 4.2 is
EOL as far as Samba is concerned. You can easily do this by going here:

It all depends if you are trying to change the passwords after the new
AD domain is created, or during the upgrade.

If it is the later, then probably not, but if you are changing them once
the domain is up and running, you can use another samba-tool command:

samba-tool domain passwordsettings set --complexity=off

Thanks for the link. Could be sufficient to use 'backported' samba
package, eg, samba from squeeze?

After, after... sorry, i've not specified it...

...apart that samba-tool in 4.2 seems does not have a --complexity=off
parameters, you mean i've to turn off password complexity, do a
password change, and the restore it (i suppose --complexity=on)?

There's really no way to set/force a password?!

Ahem, i've typed '--comploxity'... sorry... OK, option is available
in
samba-tool in 4.2, but does not seems to work:

 root at lupus:~# samba-tool domain passwordsettings set --complexity=off
 Password complexity deactivated!
 All changes applied successfully!
 root at lupus:~# smbpasswd gaio
 New SMB password:
 Retype new SMB password:
 Failed to modify account record

Hi Louis, I 'think' this guy is trying to use your packages, but as you

Sorry, i see jessie in his packages. 
I have had a look in the bug reports. 

See :  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816301 
Post smb.conf also so we can check if you have more config errors. 
>From the above link, if you have :'security = share'

Change that to 
   security = user
   map to guest = Bad User




Greetz, 

Louis
