Hi Andrew,
Tried various combinations of ", \" and ' with no success :( As a 
workaround i have made all the parameters that i could without spaces. I 
had to comment our two tests (add/remove group members through their cn) 
as they could not be shortened. I have attached new patch.
Please let me know your comments

Regards

Luk
