Hi Thomas,

In this case you should include eldap's hrl file to and use records to pattern match the results.
Matching records as tuples is considered a bad practice. 
http://www.erlang.se/doc/programming_rules.shtml#HDR23

I suggest you start with:

 -include_lib("eldap/include/eldap.hrl").

Note that you'll be dealing with a _list_ of entries. 
lists:map/2 (or list comprehension) can come in handy for further processing.

Cheers,
/A.
