Create subbranch in people

I would create subbranch in ou=people.

I tried to create a department "lan" with base parameter "/people". It create a departement ou=lan,dc=domain,dc=lan.

If I try to create a user in the departement it create it under uid=user,ou=people,ou=lan,dc=domain,dc=lan But I would something like uid=user,ou=lan,ou=people,dc=domain,dc=lan
