Wipro — Unable to login into Wipro Alumni portal

Address:	Hyderabad
Website:	alumni.wipro.com

It is not allowing me to Sign-in to Wipro Alumni Portal (Sign-up --- Sign-in --- Sign-up --- Already Registered) But NEVER LOGGED IN.

After Sign-up/registration, it says "Dear User, please click on below Sign-in button to complete the login process", when I click on SIGN-IN and provide the authentication details, it still takes me to the Sign-up page and after providing the asked details, it shows " You are already a registered user, please Sign-in to Proceed". Attaching the screenshot.
