Okay I guess I will look else where. However, I keep getting segmentation faults when try an execute the ldap command t=l.simple_bind_s(dn,pw). It is only line of code that crashes. If the have the classic expat problem, would that mean I would get a segmentation fault problem from the start. Also, ldap script works okay as a stand alone script. Thanks.
