Enable LDAP authentication failing

Enable LDAP authentication failing

(Posted this question in the Zoho Support forum yesterday in error)

Getting error:
Could not enable LDAP Authentication. Ensure Domain Controller is configured for at least one of the Imported Domains.

am however able to import users with current ldap credentials.

I am using openldap
Address/port: ldaps://xxxxxx:636 (had to add ldap server ca cert into keystore to get this going)

I have tried both the 'LDAP Server Type' as openldap as well as 'others'.

'Others' config options:
Login attr: uid
Mail attr: mail
Dist name: dn

Server logs:
[14:46:27:993]|[09-21-2011]|[com.adventnet.servicedesk.setup.util.LDAPUtil]|[INFO]|[26]|: IsLDAPAuthentication Result : false|
[14:46:27:993]|[09-21-2011]|[com.adventnet.servicedesk.utils.ServiceDeskUtil]|[SEVERE]|[26]|: FAILURE :Could not enable LDAP Authentication. Ensure Domain Controller is configured for at least one of the Imported Domains.|

There are no errors in the ldap server log when trying to activate.

I do not know how to proceed further - please advise.

Thanks.
