Cheers, I had tried using 'tcp port 389' but in needing to do a 24hr capture resulted in a lot of info. Even when splitting the data amongst multiple files resulted in 10Mb x 260 files. Opening this many files would be too much. I'm not sure of what the maximum file size WireShark can handle in opening, may give 150Mb a go instead of 10Mb multiple file sizes.

This page gives some tips on improving performance when using large capture files:

The size of capture file supported is only limited by the amount of RAM you have and CPU speed to process all of the packets. I don't think there is an official upper limit
