Freeradius LDAP problem

Hi everyone I have a problem. I set up freeradius to use a local ldap server to authenticate a user. When i say authenticate i mean check if the user is there, check their password, and accept or reject them. When i do such an authentication i get a message from freeradius saying that user is authorised successfully but when it goes to the authentication section it uses a unix module, fails and rejects the user. I tried commenting in the post auth ldap section, and commented it out again but nothing. Does the authorized successfully part mean the user is there but cant compare the passwords or something?
