mod_shared_roster_ldap issues, minimum configuration

Confused in generating Shared Roaster from LDAP

I am very much confused about all shared roaster modules, I hope someone can please direct in proper direction. So here is what I am facing issue, I have debian using ejabberd 2.1.11, installed via binary Package. I am using external auth from LDAP server.
Here is a sneak of my config file

{mod_shared_roster_ldap,[
        {ldap_base, "ou=people,dc=company,dc=com"},
      %%{ldap_groupattr,        "ou"},
        {ldap_rfilter,          "(objectClass=*)"},
        {ldap_filter,           ""},
        {ldap_gfilter,          "(&(objectClass=*)(cn=%g))"},
        {ldap_groupdesc,        "description"},
        {ldap_memberattr,       "memberUid"},
        {ldap_memberattr_format, "uid=%u,ou=people,dc=company,dc=com"},
        {ldap_ufilter,          "(&(objectClass=inetOrgPerson)(uid=%u))"},
      %%{ldap_useruid,          "uid"},
        {ldap_userdesc,         "displayName"}
]},

Well using this I can see all the user via this command ejabberdctl registered_users company.com

I have used vcard_ldap modules also, here is what I have

  {mod_vcard_ldap, [
        {ldap_base, "ou=people,dc=company,dc=com"},
        {ldap_vcar_map,
                [
                {"NICKNAME", "%s", ["displayName"]},
                {"GIVEN", "%s", ["givenName"]},
                {"FAMILY", "%s", ["sn"]},
                {"FN", "%s", ["displayName"]},
                {"EMAIL", "%s", ["mail"]}
                ]},
        {ldap_search_fields, [
             {"User", "%u"},
             {"Name", "givenName"},
             {"Family Name", "sn"},
             {"Email", "mail"}
        ]},
        {ldap_search_reported, [
            {"Full Name", "FN"},
            {"Email", "EMAIL"}
        ]}
]},

NOTE : I have disabled mod_vcard module.

When I login into IM client, tried pandion, spark, pidgin in all I cannot see anyone on the list, even when two users is logged in.. dont know why.

Other thing is when I click for offline user I can see all the user in "Company" Group. But can not in proper groups as of now I have three other group named as "Company IN", "Company AU", "Company EU".

What could be missing here, let me know if anything else is needed, I can not see any error message in logs, by looking at this it seems to be getting properly..
Please any suggesstion
