Password Expiration and SSO AD/Sapgui

Hello!!!!!

I had set SSO between AD and SAPGUI (ERP systems), our parameters ood password expiration are inactive but we want to set the following values:

login/password_max_idle_initial = 14
login/password_expiration_time = 90

I wonder if setting these new values will affect the SSO configuration, we have a lot of users who never have changed their inital/productive password.

In theory SSO avoids the validation of passwords, but I know that password expiration affects SSO between ERP and Portal, but I am not sure if this affects SSO between AD and SAPGUI (ERP systems),

Regards
