'Invalid DN Syntax' LDAP Integration

Technical assistance
13

The user’s group I’m interested in is: ou=users
my structure looks like this:

LDAP_-No_entry_selected-_Apache_Directory_Studio
LDAP_-No_entry_selected-_Apache_Directory_Studio486×648 70 KB

I need those users under c=TT but I don’t mind to import everything. I tried a lot of filter settings with objectClass but nothing works.
Any thought?
