Secure Global Desktop password can not set expired

I am using Secure Global Desktop 4.2 on Fedora Core 3. I had set the password expire period to one month. However Secure Global Desktop let me login to system without prompt me to change password or refuse my login.How could I fix the problems?

I know for sure that the active directory and the ldap ( secure ) login authority can handle expire passords and prompt for a new password, during de webtop login.

So if you store your users in a ldap database and use it self as the secure ldap server as you login authority this might work.
