SAP GRC Fiori Access Request - Data to be fetched from LDAP on Fiori instead of ECC/GRC backend

Hi All,

I am customizing/extending the GRC Access request fiori standard app, in which new input screen has been added where the First name, Last name, Email id and manager id will be coming from LDAP/ Active Directory and not from ECC system.

Can anybody let me know how to integrate or bring LDAP data to the UI screen, what process to be used because in case of any other SAP backend viz ECC,SRM it could be achieved using RFC's.

Please help for this.

regards

Aj
