HistoryLength: Integer;

HistoryLength: System.Int32;

    MbPolicy: IMetabasePolicy;
    MbPassPolicy: IMetabasePasswordPolicy;
    Lic: Object;
Begin
    Mb := MetabaseClass.Active;
    // Check out license to work with security manager
    Lic := MB.RequestLicense(UiLicenseFeatureType.Adm);
    MbSecurity := Mb.Security;
    MbPolicy := MbSecurity.Policy;
    MbPassPolicy := MbPolicy.PasswordPolicy;
    // Set number of old user passwords
    MbPassPolicy.HistoryLength := 3;
    // Save changes
    MbSecurity.Apply;
    // Check in license
    Lic := Null;
End Sub UserProc;

Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.ForeSystem;
…
Public Shared Sub Main(Params : StartParams);
Var

    MbSecurity: IMetabaseSecurity;
    MbPolicy: IMetabasePolicy;
    MbPassPolicy: IMetabasePasswordPolicy;
    Lic: Object;
Begin
    Mb := Params.Metabase;
    // Check out license to work with security manager
    Lic := MB.RequestLicense(UiLicenseFeatureType.lftAdm);
    MbSecurity := Mb.Security;
    MbPolicy := MbSecurity.Policy;
    MbPassPolicy := MbPolicy.PasswordPolicy;
    // Set number of old user passwords
    MbPassPolicy.HistoryLength := 3;
