Interface creation and LDAP authentication ...

Question

Hi...All SAP friends,
i have to work on an interface creation with the following specifications:
1. SAP Enterprise Portal gives us an URL which contains UserID
2. You have to create an interface to read the URL,
3. Connect to LDAP server...from there come to know whether it is external or internal user, meaning if it exist in LDAP it is internal otherwise it is external user
4. If the user id is internal, interface has to create a file and place it at a particular location & create a webservice for this and expose to EP
5. if not it should give an alert saying it is an external user id
Please help me out how to start and what to do..!
Thank you.

Hi,
These are the main steps,
***Assume that you know basic of authentication methods and how to define those in Apex
01. Create a function to authenticate the user
a. Check on the database whether user is exists
b. If exists then authenticate that user with LDAP
c. If user doesnot exists or authenticate failed then return false
d. If user exists and authentication success then return trueSignature of the function
FUNCTION <fucntion name> (p_username VARCHAR2, p_password VARCHAR2)
RETURN BOOLEAN;
* Makesure that you do both inside the one procedure
02. Create another function to check the page level authorization(if you need pagelevel verification. But if all users has same permissions on the aplication this is not necessary)
03. Create a new authentication
a.Go to Application Builder
b.Shared Component
c. Authentication Schemes(under Security)
d. Click "Create"
e. Select "From Scratch"
f. Proceed with the wizard and define "*Page Sentry Function*" (Only when you ahve page level authorization- BAove 2) and "*Authentication Function*"04. Set new authentication schema to current
a. Goto "*Change Current*" Tab
b. Sleect the new schema from the list
c. Click Next and proceed with wizard.
