Auditing Accesses inside the database and Timesheet cross‐gchecking (Absent but logged on, not assigned to a Site but still authorized etc..)

How to integrate OID/SSO with WebLogic
“Forms (11g) will not be specifically coded to use, nor tested with Oracle Access Manager. Other Oracle products, such as ADF, Web Center and Portal, will also support Oracle Single‐Sign‐on.
Oracle has plans to support Oracle Access Manager in future versions of Oracle Forms 11g.”

What is done at the back...
Jdeveloper creates :pjazn‐data.xml: Set security rules & permissions + dev/test store for testing only (skipped on deployment)
and updates :web.xml: Set type of Authentication selected.weblogic.xml : where users are mapped to role (by default a generic principal (user) is mapped to a Weblogic role “valid‐users” (authenticated user)adf‐config.xml: To indicate that ADF security is enabled & handled by JPS (Java Platform Security)

Authorization : Roles & Pages Security
Application RolesADF application specified role, ADF Authorization are set on these roles.
Enterprise RolesRoles assigned to the ADF user from the Credential/Identity Store (Oracle g y (Internet Directory)
Application Role is mapped to Enterprise Role allowing pp pp p gdeveloper to use roles and map them later to final Roles.
Roles are applied to pages with “View” permissionRoles are applied to pages with View permissionOther permissions are only applicable if you use WebCenter

What we have at this stageWhat we have at this stage
A user with an OID account and OID Groups (enterpriseA user with an OID account and OID Groups (enterprise roles) gets a SSO login form to identify himself when trying to access an ADF application (all pages being y g pp ( p g gprotected by ADF Security).
Once authenticated, he can navigate to the page if he has the necessary enterprise role (mapped to the application role set to protect the page)application role set to protect the page).

How it works (Guideline only. To Show extensibility/flexibility of the Framework)
1 User Login is fetched from ADF Context1. User Login is fetched from ADF Context.
2. From a “Project List” module and a “Project Switcher” Taskflow, a selected Project is set in the database. Any direct access to j yModule takes the Project from the database.
3. When accessing an application we store in the AM Session our context parameters: Project Code, User Login, Module Code,etc..
4. Module Access Right for Project is checked from the database (in case Module accessed directly via Module URL)(in case Module accessed directly via Module URL)
5. Database Client Identifier & Module Environment are set in the Database for Auditing purpose & other needsDatabase for Auditing purpose & other needs.
General Construction Co.Ltd
6. A “Module access” audit event is logged in the Database
7. When a page is accessed, session parameters are stored (if not already done) in a Session bean.
8. User’s Privileges Codes for Module/Project is fetched from the Security Database and stored in HTTP session as a Map.
9. Bind Variables on our View Objects (VOs) are automatically replaced by our parameters value to filter data at VO levelreplaced by our parameters value to filter data at VO level when VOs are executed.
10 We have a session bean method (SecurityScope userinRole)10. We have a session bean method (SecurityScope.userinRole) that is used in EL to check Privileges from our HTTP session Map to Render or not a Component.

VOs Bind Variables are automatically replaced by our parameters value to filter data per Project at VO level
Parameter naming convention : Parameter name must be consistent,For ex. a projectCode parameter defined in the AM must have the same name as the VO bind variable name.
All ViewObjects use a custom based class “BaseFilteredViewObject” where executeQuery and executeQueryForCollection are overridden :
setGlobalVariablesValues();super.executeQuery();
private void setGlobalVariablesValues() {VariableValueManager vm = ensureVariableManager();Variable[] vars =vm.getVariablesOfKind(Variable.VAR_KIND_WHERE_CLAUSE_PARAM);
for (Variable var : vars) {Object voVarValue = vm getVariableValue(var getName());Object voVarValue = vm.getVariableValue(var.getName());if (voVarValue == null || voVarValue.toString().isEmpty()) {vm.setVariableValue(var.getName(),
getApplicationModule().getSession().getUserData().get(var.getName()));}
}}
