I have to implement single sign-on functionality between Facebook and sap Netweaver AS Java 7.31. So that, UME users should be able to login into SAP Netweaver Administrator without entering there SAP Netweaver user id and password. Instead, they should be able login by entering there Facebook user id and password.
For example:
Suppose there are 5 UME users accounts in SAP Netweaver Administrator with the following names or ids "A", "B", "C", "D", and "E". When user "A" clicks on Facebook login button he has to login into his account on SAP Neweaver portal and it should be same for the other users also.
Could anyone please guide me or share some helpful links which might help me to implement the above functionality.
