OpenLDAP account policy


I just got ldap up and running, authenticating user logins through Radius.

However I am still missing on the account lockout feature.

Users should have 3 tries to get the correct password. Else the account will lockout. Tried a few methods using pam but it just won't synchronise account information.

I been looking around LDAP configs and found nothing that can do this, am I looking in the right place or it's an external feature?

I reverted to Freeradius + /etc/passwd authentication, but it doesn't seem to go through pam_tally to check if a user has exceeded the number of retries, and deny the user if he has exceeded 3 password retries

pam_auth is loaded pointing to radiusd



/etc/pam.d/radiusd
Code:
#%PAM-1.0
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
session    include      system-auth
/etc/pam.d/system-auth-ac
Code:

# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      pam_env.so
auth        required      pam_tally.so deny=3 no_reset no_magic_root

account     required      pam_unix.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     required      pam_permit.so

password    requisite     pam_cracklib.so try_first_pass retry=3
password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
password    required      pam_deny.so

session     optional      pam_keyinit.so revoke
session     required      pam_limits.so
session     [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid
session     required      pam_unix.so
Presently, even with a locked account, a user could still get in if the correct password was supplied.

Is my pam_tally configured wrongly or radiusd (pam_auth or rlm_unix module) just simply doesn't want to look at pam_tally to decide whether to deny locked accounts?

Thanks for the help in advance.
