LDAP - "mail" attribut

Hey Guys,

im tryiging to configure my the LDAP authentication (destination LDAP: openLDAP).

But i have the problem, that im only able to authenticat the "uid" attribut. If i try "mail" in my LDAP, all the time i get the message "invalid password".

ldap.cfg
------
ldap_conn_host=oldap.mydomain.de
ldap_conn_port=389
ldap_conn_secure=false
ldap_admin_dn=UID=openmeetings,OU=xxx,OU=xxx,DC=xxx,DC=de
ldap_passwd=xxx
ldap_search_base=OU=xxx,OU=xxx,DC=xxx,DC=de
ldap_search_query=(mail=%s)
ldap_search_scope=ONELEVEL
ldap_auth_type=SIMPLEBIND
ldap_userdn_format=mail=%s,OU=xxx,OU=xxx,DC=xxx,DC=de
