From Wikipedia: "Authentication is the act of confirming the truth of 
an attribute of a datum or entity. This might involve confirming the 
identity of a person or software program, tracing the origins of an 
artifact, or ensuring that a product is what its packaging and labeling 
claims to be." That's how we know who an application talks to.

From Wikipedia: "Authorization is the function of specifying access 
rights to resources." After authentication we know the person, but we 
still unsure whether it's supposed to access a given resource and hence 
the need for authorization.

To get to know Openldap, read: http://www.openldap.org/doc/admin24/

Everything depends on what you are trying to do, your project needs.

An example for AAI services would be something like OpenLDAP + Kerberos 
or Radius. Google for AAI / SSO systems.
