Problem using pam_ldap in RedHat 9

[Rodrigo S Wanderley]

Hi,

  Im having some problem trying to autenticate using an ldap database.  
My /etc/pam.d/su looks like this:

auth       required     /lib/security/$ISA/pam_unix.so
auth       sufficient   /lib/security/$ISA/pam_ldap.so use_first_pass
account    required     /lib/security/$ISA/pam_permit.so
password   required     /lib/security/$ISA/pam_permit.so
session     required    /lib/security/$ISA/pam_permit.so

I used the pam_permit.so trying to focus only on the auth method.

After spending some time in this problem I decided to get the source 
code of pam_ldap.so, Ive used some printfs on it and saw that it was 
returning 0 (PAM_SUCCESS) but su keeps giving me 'su: incorrect password'.

Had anyone have similar problem and found the answear?

---> Example Session
# su rodrigo    # rodrigo is an ldap user
password: ******
su: incorrect password
--->

Any information that you need, please let me now.

thanks in advance,
  RSW

OBS: Had no problem to configure Libranet and RH 7.2
