Portal-Logon policy for initial password

Hi to all,

I'm trying to set a parameters for the password administration, on a Portal that runs on a Netweaver Java 7.4 platform.

My customer has two different policy for the validity of the initial password of the users and for the productive password.

I know that exist a parameter ume.logon.security_policy.password.expire_days that defines the number of the days for the productive password validity, after this value the users have to change their password (default is 90 days).

Now i'm looking for the initial password "expire days parameter", anobody can help me?

the UME is managed by the Java stack, and my users only can perform a basic authentication.

Thank you,

Mark
