Hi this occurs when the maximum machine account password age expires.
It sounds like you're running into an issue with the default SSSD-AD value for
ad_maximum_machine_account_password_age of 30 days before attempting a renew which is greater than what your domain policy is set to. Try dropping the
ad_maximum_machine_account_password_age flag to 15 or 10 days depending on personal preference.
It is also important to run RSOP to determine what value actually is for your domain.
Here is some appropriate reading to help confirm this statement and address the relevant required config.
