Account lockout using Openldap
What is the best way to implement account lockout in openldap? I have an openldap server with Ubuntu desktop client connecting to it for authentication. I want he accounts to locked out after say 5 failed authentication attempts

I have enabled ppolicy layout in slapd.conf.

Code:
overlay ppolicy
ppolicy_default “cn=default,ou=policies,dc=example,dc=in”
ppolicy_use_lockout

I have also imported a policy as given blow now. This is the output of ldapsearch

Code:
# policies, example.in
dn: ou=policies,dc=example,dc=in
ou: policies
objectClass: top
objectClass: organizationalUnit

# default, policies, pramata.in
dn: cn=default,ou=policies,dc=example,dc=in
objectClass: top
objectClass: device
objectClass: pwdPolicy
cn: default
pwdAttribute: userPassword
pwdMaxAge: 7776002
pwdExpireWarning: 432000
pwdInHistory: 0
pwdCheckQuality: 1
pwdMinLength: 8
pwdMaxFailure: 5
pwdLockout: TRUE
pwdLockoutDuration: 900
pwdGraceAuthNLimit: 0
pwdFailureCountInterval: 0
pwdMustChange: TRUE
pwdAllowUserChange: TRUE
pwdSafeModify: FALSE

In the client(Ubuntu Desktop) I added the following line /etc/ldap.conf

Code:
pam_lookup_policy yes

Still not working. Please advice me on what I did wrong in this.

slapo-auditlog

SLAPO-AUDITLOG(5)						File Formats Manual						 SLAPO-AUDITLOG(5)

NAME

       slapo-auditlog - Audit Logging overlay to slapd

SYNOPSIS

       /etc/openldap/slapd.conf

       /etc/openldap/slapd.d

DESCRIPTION

       The  Audit  Logging  overlay  can  be used to record all changes on a given backend database to a specified log file. Changes are logged as
       standard LDIF, with an additional comment header giving the timestamp of the change and the identity of the user making the change.

       For Add and Modify operations the identity comes from the modifiersName associated with the operation. This is  usually	the  same  as  the
       requestor's identity, but may be set by other overlays to reflect other values.

CONFIGURATION

       This slapd.conf option applies to the Audit Logging overlay.  It should appear after the overlay directive.

       auditlog <filename>
	      Specify the fully qualified path for the log file.

       olcAuditlogFile <filename>
	      For use with cn=config

EXAMPLE

       The following LDIF could be used to add this overlay to cn=config (adjust to suit)

	      dn: olcOverlay=auditlog,olcDatabase={1}hdb,cn=config
	      changetype: add
	      objectClass: olcOverlayConfig
	      objectClass: olcAuditLogConfig
	      olcOverlay: auditlog
	      olcAuditlogFile: /tmp/auditlog.ldif

FILES

       /etc/openldap/slapd.conf
	      default slapd configuration file

       /etc/openldap/slapd.d
	      default slapd configuration directory
