Restriction password - Group policy

Hi,

I established a group of policy on passwords:
- Number of characters: 5
- Life: 60 days
- Saving previous password: 3

This morning a user logs on and managed to put the same password and with 3 characters. !?!? ??
I need your lights, why this policy was not applied

Thank you

rsop.msc on the PC with the user

The policy is effectively implemented on the PC in question, with the proper user connected.

Is a user with local admin rights bypass a group policy?
