[Samba] new password empty

[Maurizio Marini]

Hi there
i have a very strange issue:
%n is empty, for sure.


	ldap passwd sync = No
	unix password sync = Yes
	passwd program = /usr/bin/php -f /etc/samba/scripts/chgpwd.php %u %n
	passwd chat debug = yes

this small php script does log:

Apr 29 11:19:13 pdc myScriptLog[29555]: change password: prova - %n

if i use smbldap-passwd

;       passwd program = /usr/bin/php -f /etc/samba/scripts/chgpwd.php %u %n
        passwd program = /usr/sbin/smbldap-passwd -u %u
        passwd chat = "New password:" %n\\n "Retype new password:" %n\\n "changed"
        passwd chat debug = yes

i added some logging to it:
/var/log/perl.log

Apr 29 11:20:17 pdc smbd[592]:   decode_pw_buffer: check that 'encrypt passwords = yes'


as far as i can see, smbldap-passwd does not receive %n and ask it more and more 3 times.

Why is it not receiving new password by windows client?
any advise would be apreciated
