ldap authentication error.

[DK]

Hi, 

I´m  trying to configure freeradius to authenticate to LDAP server.
I use an users file and ldap server to authenticate, the first one
goes well but when I ytry to do it with LDAP server,  a get this
error.

rlm_ldap: - authenticate
rlm_ldap: Attribute "User-Password" is required for authentication.
Cannot use "CHAP-Password".
  modcall[authenticate]: module "ldap" returns invalid for request 1
modcall: group Auth-Type returns invalid for request 1
auth: Failed to validate the user.


Any idea? 

Thanks
