SAP user authentication in ABAP program

[Former Member]

We are building a custom application in SAP.

One of the functionality required is - Before printing a certificate ,we need to verify SAP user ID and password.

Is there any FM in SAP which I can use or any other way by which I can ask user to enter his user ID and password and then autheticate it against actual SAP credentials.
