It's the only mailing list for python-ldap. So you're welcome to post here. 
But please use an appropriate subject line for your own topic. Thanks.

When I'm doing LDAP programming coaching this is a frequently asked question.

My answer is always: Don't do it. It's a bad habit. Implement proper 
reconnecting instead.

BTW: That's what ldap.ldapobject.ReconnectLDAPObject is for. But you have to 
understand what you're doing. And you have to understand the security 
implications of storing credentials in the ReconnectLDAPObject instance 
especially when pickling the instance on disk.

Ciao, Michael.
