Need help to correctly set LDAP groups

Hello,

I just updated Openfire from 3.7.1 to 3.9.3 and it seems I cannot make it read any group from AD or at least to display all users in Spark.

I have the following AD structure

DC=<domain component>,DC=<domain component>

     OU=Accounts

          OU=1200                        OU      (company departments)

               CN=John Doe             user

               CN=OPENFIRE          user     (openfire administrator)

               etc

          OU=1400

               CN=Jane Doe

               etc

          OU=Administration

               CN=John Doe_administration

          OU=7000

               CN=John Doe_7000

               OU=7100

                    CN=John Doe_7100

          etc.

     OU=<Organizational Unit>               (some OU's not needed for Openfire)

     CN=<Common Name>                    (some CN's not needed for Openfire)

     OU=Groups

          CN=1 GNR                    group     (empty groups, not used anymore)

          CN=All Users                 group     (distribution group - universal, users with email and also some users without email)

I have set the following:

Base DN:      OU=accounts,DC=<domain component>,DC=<domain component>

Admin DN:     CN=OPENFIRE,OU=1200,OU=accounts,DC=<domain component>,DC=<domain component>

User mapping set as default.

Group Mapping set as default (tried several settings but no success)

I have tested "1. Connection Settings" - OK

I have tested "2. User Mapping" - OK - rahdom users profile OK

I have tested "3. Group Mapping" - Error, no groups shows

Need help to add users in Spark clients eighter by their groups or at least to show all users grouped by online/ofline status

In Openfire 3.7.1 I had all users grouped by online/offline status

I don't really need groups.

Thank you
