Added a new function - getUserInfo to AuthInterface and AuthLdap
The function returns a string array for a given username. the array contains the name, organization name and email address of the user. In case of ldap, it is cn, o and mail attributes for ldapbase=username
Modified AuthSession to use the above function when a user logs into Metacat and store the name of the user in the session. if needed, the organization information can also be stored in the session.
