Single LDAP java login on Liberty server

Question

I want to implement Single Sign on a Websphere-Liberty server using Java. I want to authenticate users using LDAP.

I searched a lot, but could not find an exact example. I also checked every available stack overflow example. but no luck.

It would be great if you could provide demo or sample code for it.

Thanks in advance.

update: I was able to implement the same with waffle .. but waffle does not work with Linux / Unix ... can someone help me?
