But the environment is global for all threads.
I don't know how ldapsearch works, but can't you pass it an additional  
argument, instead of setting an environment variable? From the long  
commandline you're building, I bet it has a suitable option.
Or, instead of os.system, use subprocess.Popen, wich lets you specify the  
new environment of the child process.
