OpenLDAP authentication

Hello,

I have a predominantly Windows/Linux network running here, and we have recently purchased 3 Mac laptops which also need integration to the network. I would like to enable logins with those Macs via the (Zimbra) OpenLDAP server we have running. I have this working for the Linux machines via pam_ldap but I am having a little more trouble with the Macs.

I have used Directory Access to specify an LDAPv3 server and configured it to use the RFC 2307 (Unix) mappings. If I run a lookupd -d from the terminal, I can query for my username and see the LDAP entry returned, so communications with the LDAP is working:

> userWithName: user
Dictionary: “DS: user user”
_lookup_agent: DSAgent
_lookup_validation: 1193700085
gid: 1024
home: /home/directory
name: username fullname
passwd: {SSHA}big passwd hash {SSHA}the same password hash
realname: fullname
shell: /bin/bash
uid: 1024
+ Category: user
+ Time to live: 43200
+ Age: 0 (expires in 43200 seconds)
+ Negative: No
+ Cache hits: 0
+ Retain count: 5

When I try and log in however, the login window vibrates and refuses to let me in.

Zimbra hashes the password in the LDAP tree with SSHA. Setting the DirectoryService to debug, shows a bunch of output, but nothing to indicate it is trying to use SSHA. The relevant debug output is here:

Can anyone shed any light on this?

Cheers,
