Subject: Re: Update - it's the search_s in ldapmodule which leaks when 
    usingldapmodule

I inherited some of the setup here so I didn't even try to grok why
"import ldap" worked when ldapmodule.so was available - it was always
called that - not _ldapmodule.so - I suspect the initial setup.

Anyhoo, it works as intended now. 

I don't use the cache so I'll turn it off - I didn't realise it affected
the client libraries - thanks. I'll let you know if it leaks differently
(!).

<a few minutes later>

Nope, no apparent difference.

I reverted to a fresh copy of the original tar and compiled with that
one mod. to the Makefile.in - that tarball appears fit for human
consumption.

May I suggest you might add to the readme, something along the lines of
your reply below 
"
the init function is usually called init_ldap() so the module
is called _ldap. when installed properly theres a ldap.py file that
wraps it.
"

Note for zope users: After the configure and make steps, put the output
(Modules/_ldapmodule.so) and Lib/ldap.py into your [zope]/lib/python
directory where it will be found by external methods and products.


for future generations of grateful end users.....
