- hooked into events system, so requests can be truly async and won't interfere with other processing happening at the same time - uses NTSTATUS codes for errors (previously errors were mostly ignored). In a similar fashion to the DOS error handling, I have reserved a range of the NTSTATUS code 32 bit space for LDAP error codes, so a function can return a LDAP error code in a NTSTATUS - much cleaner packet handling (This used to be commit 2e3c660b2fc20e046d82bf1cc296422b6e7dfad0)
