LDAP group filter wont work

I get the User login with LDAP working, but when i try to activate the group membership, login isn’t possible.
My ldap_auth.conf:
user: ***
password:***
host: myhost=
port: 389
timeout: 40
base: ‘dc=sec,dc=t-labs,dc=tu-berlin,dc=de’
group: ‘cn=oneadmins,ou=groups,dc=sec,dc=t-labs,dc=tu-berlin,dcde’
user_field: ‘uid’
group_field: ‘member’
mapping_generate: true
mapping_timeout: 300
mapping_filename: server1.yaml
mapping_key: GROUP_CN
mapping_default: 1
rfc2307bis: false

Ldap Structure:
157 cn=oneadmins,ou=groups,dc=sec,dc=t-labs,dc=tu-berlin,dc=de
2503 cn: oneadmins
2504 objectClass: groupOfNames
2505 member: uid=username,cn=user name,ou=users,dc=sec,dc=t-labs,dc=tu-berlin,dc=de

oned.log:

As I said the login against LDAP with the group line commented in the ldap_auth.conf is working, only when I try to allow login only to Users in a specific group.
Maybe somebody sees my error?
