You can't enforce different passwords between users, but you can enforce strong passwords so they will have to think of a password different then default weak passwords:

Hope this helps

Hello Jos,

Thank you for reply. BUt I guess I couldnt tell my problem. I dont want to enfore different passwords between users.  

For example my local user’s password :A123! and and when my password expire and when I must change my password I should not use “A123!” again

is it possible?

Ah my apologies, I misunderstood.
Yes you can by using this additional setting:

Hello Jos,

THank you for the link. I have added but it doesnt work, 

@ETO , Try opening the link in incognito mode.  I often get that issue due to a bad cache/cookie.

Hello 

I have added the addtional settings and I changed the password But I could use the pervious password 

Should I restart server or anyth,ng?

@ETO , just to confirm, you set the Additional Setting to TRUE, right?
