Re: Do I need to ldap_memfree after ldap_get_lderrno? SDK docs say yes.

Eek - that's bad.  You should not free those pointers.   Here is the 
actual code:
		if ( m != NULL ) {
			*m = ld->ld_matched;
		}
		if ( s != NULL ) {
			*s = ld->ld_error;
		}
		return( ld->ld_errno );

It returns pointers to the internal data structures - you should never 
call free on these pointers.

Can you point me to the documentation you referred to?

Yes - see above.

I'm not sure.  Typical usage is that you only call ldap_get_lderrno if 
some LDAP API function returned a value other than LDAP_SUCCESS.
