problem with ldap authentication Sun directory server

[comefrom]

hi everyone
I'm new for openmeeting .A few days ago, i tried to integrated ldap authentionation with my Sun directory server
It's not successfull.what i see , the debug log file always show this line
"
Authentification to LDAP - Server start
DEBUG 07-15 07:10:29.779 LdapAuthBase.java 70069464 133 org.openmeetings.app.ldap.LdapAuthBase [NioProcessor-1] - loginToLdapServer

I'm confusing that openmeeting can only support Openldap?How about's another ldap servers?
In case, i'm using user database with Sun directory server
As below, the configuration file looks so good

ldap_server_type=OpenLDAP
ldap_conn_url=ldap://myldap.com:13892
ldap_admin_dn=uid:omuser,ou:users,o:test,c:com
ldap_passwd=12345
ldap_search_base=o:test,c:com
field_user_principal=uid
ldap_sync_password_to_om=no
ldap_auth_type=SIMPLE
ldap_user_attr_lastname=type-id
ldap_user_attr_firstname=uid
ldap_user_attr_mail=uid
ldap_user_attr_street=st
ldap_user_attr_additionalname=description
ldap_user_attr_fax=telephoneNumber
ldap_user_attr_zip=st
ldap_user_attr_country=st
ldap_user_attr_town=st
ldap_user_attr_phone=telephoneNumber

Any helps are appreciated
Thanks so much

I have no direct experience with Sun Directory Server, however I found
using a packet sniffer invaluable to debug with.

Thanks shouldbeq931
I'm used to sniff traffic using snoop command to analyze packets sending out and receiving from Sun directory server
I can't see abnormal, what i confused that openmeeting can't support Sun directory attributes and
it can't recogzine ldap format return from Sun directory server when doing ldapsearch
Anyone else has experienced on Sun directory server or another ldap servers ?
Pls help
Thanks
