How does your source code look like ? I have the suspicion that you give
wrong arguments to the ldap function. e.g. where the hostname goes you put
hostname:port.

Hi, all:
Now I am able to use ldapsearch (the OpenLDAP utility) to do SASL binding
after a successful kinit operation. The previous error 82
(ldap_sasl_interactive_bind_s: Local error) is due to two reasons.
1. SASL binding should use LDAP server's hostname, instead of IP address.
2. DNS servers should be correctly set up to resolve the hostname to its IP
address.
Now I turn back to use MozLDAP library to code SASL support, but it doesn't
work. The error is still this "82 Local error". In the network trace
captured between the client printer and the server, I found the following
interesting packets:
========================================

...... /* simple binding/search follows */
========================================
The server is "13.198.98.35", while the client is "13.198.98.107". Packet
32~37 are all related to SASL binding, while packet 38~39 onwards are for
simple binding and search (and they are successful, coz the IP address is
correctly resolved out). The code is arranged in such a manner that if SASL
binding fails, it will turn to simple binding.
In the enrionment setup, the server is an AD in Windows 2003 Server
Enterprise Edition. It's hostname is "sesswin2003". The server is also a
primary domain controller, with the domain name "sesswin2003.com". In the
printer's LDAP setup WebUI page, the server's hostname is set to
"sesswin2003". And the printer is placed in the domain of "sesswin2003.com".
This domain is set in the printer's TCP/IP WebUI page.
In simple binding, we can see the DNS request from the client is in the
correct format, i.e. with LDAP server's hostname suffixed with the domain
name. And the server can resolve correctly, and sends the IP address back to
the client.
But, in SASL binding, the DNS request from the printer seems incorrect. It
inserted the port number 389 and a space character between the hostname and
the domain name. Thus, it is not a correct FQDN, and the server can't
resolve it.
Is the insersion a defect of MozLDAP library, or SASL library?
The caller seems innocent:

========================================
The parameters passed to MozLDAP are all the same. But the binding results
are different.
Looking forward to help,
