Submission from: (NULL) (65.207.4.130)
In libldapcpp, there is a memory leak in the LDAPAsynConnection class.
ldap_initialize() allocates memory which is never freed. This memory (ld
structure) should be freed by a call to ldap_unbind() in the class destructor
and other places where the ld structure is replaced with a new one.
I have included a patch against git master HEAD below.
