No, this is not a timeout problem. If it was, then the exception  
returned by the server would tell you so.

Instrument the code in the LDAPUserFolder so it writes out queries to  
a file, for example. You just want to find out what the last queries  
are before things go wrong. The goal is to take the LDAPUserFolder  
out of the equation and provoke this behavior with just python-ldap.
