remove or improve AuthLdap.getGroups logging statement
30% of the metacat.log file (in SANDBOX UCSB) is this somewhat useless warning:
"[WARN]: AuthLdap.getGroups - The user is in the following groups:  [edu.ucsb.nceas.metacat.AuthLdap]"
Since the line does not even specify the user, what value does this WARNING serve?
It should either be removed, downgraded to INFO (are there other log INFO lines that would give this context?), or refactored to be more useful.
