Hi,

I am trying to implement password policy in OpenLDAP.

There are already similar postings on the same issue. But I tried all the possible solutions and now I am really tired after one week.

Here are the details about my problem

Operating System: Red Hat Linux ES 5.0

OpenLDAP Release: 2.3.39

During the addition of userPassword node I get the following error.

ldapadd -f /root/openldap/openldap-2.3.39/servers/slapd/schema/paswd_policy1.ldif -D "cn=Manager,dc=xyz,dc=com" -w secret -x
adding new entry "cn=default,ouname=ppolicy,oname=P_Policy,dc=xyz,dc=com"
ldapadd: Invalid syntax (21)
        additional info: pwdAttribute: value #0 invalid per syntax

Then after reading some of the issues related to it, I tried every possible solution. I added overlay path in my slapd.conf and I got the following error.

./slapd -f /root/openldap/openldap-2.3.39/servers/slapd/slapd.conf -d 1
@(#) $OpenLDAP: slapd 2.3.39 (Aug 25 2008 11:38:51) $

Following is my configuration file snapshot:-

#       Require 112-bit (3DES or better) encryption for updates
#       Require 63-bit encryption for simple bind
# security ssf=1 update_ssf=112 simple_bind=64

# Sample access control policy:
#       Root DSE: allow anyone to read it
#       Subschema (sub)entry DSE: allow anyone to read it
#       Other DSEs:
#               Allow self write access
#               Allow authenticated users read access
#               Allow anonymous users to authenticate
#       Directives needed to implement policy:
# access to dn.base="" by * read
# access to dn.base="cn=Subschema" by * read
# access to *
#       by self write
#       by users read
#       by anonymous auth
#
# if no access controls are present, the default policy
# allows anyone and everyone to read anything but restricts
# updates to rootdn.  (e.g., "access to * by * read")
#
# rootdn can always read and write EVERYTHING!

Trust me I did R & D for 7 days. Even I did a free installation of same version and of newer version(2.4.11 release) also I got the same error.

Can you please tell me the steps to make this working. Now it has become matter of life and death for me and I will do possibly anything resolve it.

Thanks in advance for your help.

Thanks & Regards,
