[Samba] pdbedit - password age

[Radek]

Hello, 

I try to force users to change password once a given period using his
command:


#pdbedit -P "maximum password age" -C 300 



It works only for "new" users (users created after first first launch of
this command), "old" users are not affected, passwords doesn't expire. How
to do his for "old" users?




I would be pleased for your help. 
Regards.

Radek
