NIFI LDAP configuration for Authorization

Really appreciate if you can guide here.

Our ldap structure is as below. user 1 : CN=user1,OU=nonAssociates,OU=usersAndGroups,DC=adomain,DC=company,DC=com user 2 : CN=user2,OU=Associates,OU=usersAndGroups,DC=adomain,DC=company,DC=com

Now in the authorizers.xml configuration when I give below, it works fine. But it gets only user1.

    <property name="User Search Base">OU=nonAssociates,OU=usersAndGroups,DC=adomain,DC=company,DC=com</property>
    <property name="User Object Class">user</property>
    <property name="User Search Scope">SUBTREE</property>
    <property name="User Search Filter"></property>
    <property name="User Identity Attribute">cn</property>
    <property name="User Group Name Attribute">CN</property>
    <property name="User Group Name Attribute - Referenced Group Attribute"></property>

When I give below to consider both the users, NIFI is not staring up. It doesn't have any errors either.

    <property name="User Search Base">OU=usersAndGroups,DC=adomain,DC=company,DC=com</property>
    <property name="User Object Class">user</property>
    <property name="User Search Scope">SUBTREE</property>
    <property name="User Search Filter"></property>
    <property name="User Identity Attribute">cn</property>
    <property name="User Group Name Attribute">CN</property>
    <property name="User Group Name Attribute - Referenced Group Attribute"></property>

Can you please help understanding how i can get both user1 and user2. My thought was i only need to change the search base to OU=usersAndGroups,DC=adomain,DC=company,DC=com. THere are no errors in the DEBUG log when i use the search base as OU=usersAndGroups,DC=adomain,DC=company,DC=com.

But it keeps saying below indefinitely.
