ldap_str2dn() and ldap_dn2str() reentrant?

[Michael Ströder]

HI!

Routinely in the C module part of python-ldap all calls to libldap functions
are wrapped by a thread lock. But I wonder whether that's really necessary for
all of them, especially regarding ldap_str2dn() and ldap_dn2str().

Ciao, Michael.
