Add logging wrappers to LdapService calls (#442)

* Add logging wrappers to LdapService calls

* Log auth call wrapper on debug as well

- Add log statement for successful auth - we don't expect this to be called often, but if we have it enabled we are prob paying close attention to some auth-related issue - seems helpful to give ourselves more insight as to what's happening with user auth requests.
