Dear all,
I am experiencing an error when trying to use the quick usage example posted on
the ldaptor github page https://github.com/twisted/ldaptor . I have included
the starttls command to promote the connection to an encrypted one, but I am
experiencing an deprecation warning:
DeprecationWarning: LDAPStartTLSInvalidResponseName.__str__ method is
deprecated and will not be used for getting bytes representation in the future
releases, use LDAPStartTLSInvalidResponseName.toWire instead
category=DeprecationWarning)
This puzzles me as I cannot track this error down. The usual strategy to
introduce debugging print statements or start the debugger like "import pdb;
pdb.set_trace()" does not work. I would appreciate help here how to debug this
deferred code.
Besides this warning I am receiving no output whatsoever. Also print statements
in the example method do not print anything, which is strange to me.
To debug it on a networking level, I have wiresharked the ldap communication
and it seems fine (see below):

I have posted the example code with the starttls command in this gist:

Thanks for your help!
Best regards,
