signature of ldap.open changed?

[Jens V. <je...@zo...>]

now that i got beyond the changed importing semantics i notice that the 
"open" call to open a new connection has a *different* signature?

can someone explain what the reasoning is? and, what's even more important,
  how is anyone supposed to support both versions and test for them 
successfully in the code without some really ugly workarounds?

again, i don't see this documented anywhere unless i actually step into 
the code or notice the module spewing uncontrollable debug messages onto 
the console because what i pass in as the port number all of a sudden gets 
interpreted as a trace level...
