PUMA API for anonymous users

For creating portlets like signUp or forget Password we need the puma api to access the user information .But before accessing attributes you have to give following  access rights others wise you won't be able to access the values.
1.From the admin console go to resource permission.

2.Select the User Groups.

3.For All Portal User Groups give the anonymous access  for USER,Editor ,Manager,Security administrator.

After that your code will work fine.
