Hello, i'd like to know under which license this code was puplished? Is it opensource? Cant find any information anywere? would like to use it in an academic projekt.

cool thanks! :)

cool great work

Will use it in my project !!! Thanks :)

Great man, it worked for me. Good job!

which python module did you use for ldap

@cemdrk it is from 2011 so I don't remember exactly which module it was. Probably it will work with little modifications with any ldap module.
