If the port is omitted, the default port will be used. The lookup method takes one or more parameters. The first parameter is the specifier to search for in the name directory. The name and nickname values are normal strings. These parameters can be passed as an array.
Field names are case insensitive.
The lookup method returns a scalar containing an error string if there was a problem. This error string may be printed as an explanation of the error. The keys to the associative array are the field names returned from the name directory, as requested by the lookup method. This module may be used for any web pages on Dartmouth's web site.
