Issue with Firefighter password being deactivated

Hi Experts,

We are on GRC AC 10.0  Firefighter SP13. Every now and then we have the password for the  firefighter id becomes deactivated and next time some one tries to login with that FFID it tells them password is not available. Once we reset the password it becomes active again.

Please advise how can we stop the Firefighter id from becoming deactivated without changing the SSO system parameter in production systems.

Thanks in advance!

Regards,

Salman
