I am new to LDAP, and I want to add password policy using the class pwdpolicy, but every time I get the error :
ERR_04269 OBJECT_CLASS for OID pwdpolicy does not exist!
Here is the how i try to add it:
dn: cn=Default Password Policy,ou=pwpolicies,dc=example,dc=com
objectClass: top
objectClass: device
objectClass: pwdPolicy
cn:Default Password Policy
pwdAttribute: userPassword
pwdMaxAge: 7776002
pwdExpireWarning: 432000
pwdInHistory: 3
pwdCheckQuality: 1
pwdMinLength: 8

pwdLockout: TRUE
pwdLockoutDuration: 900
pwdGraceAuthNLimit: 0
pwdFailureCountInterval: 0
pwdMustChange: TRUE
pwdAllowUserChange: TRUE
pwdSafeModify: FALSE
I changed the slapd.conf in WorkspaceLDAP\openldap\servers\slapd
maybe I configured wrong slapd file
Here is my slapd.conf :
include %SYSCONFDIR%/schema/core.schema
include #SCHEMADIR#/core.schema
include #SCHEMADIR#/cosine.schema
include #SCHEMADIR#/inetorgperson.schema
include #SCHEMADIR#/rfc2307bis.schema

Can i check somehow witch slapd file my server is using or if the configuration is correct?
You have to add and configure the ppolicy overlay in slapd.conf or your online configuration, whichever you're using.

I'm new to LDAP and for a school project I have an access to part of my school LDAP. I can bind with users that are in a Organizational Unit.
When I bind, I am able to see my password and not any other passwords from other users (That's normal I guess for security reasons).
So I have exported the LDIF of this LDAP and imported it on my own LDAP server for leaning purposes.
ldapsearch commands works well and I retrieve all entries (excepted password and that's normal).
So now, I try to bind with any user, I've added password by Apache Directory Studio in each LDAP Users (inetorgPerson under the ou where I usually search).
However, I can't bind.
I guess that it is due to wrong access rights.
I know that I must use ldapmodify command and that I need to forge a directive like access to * by * read (with less rights than * but it could be great to begin with).
However, I cant find how to use this directive with ldapmodify.
I think that I must create an LDIF file to modify config but I don't understand which entry I should update.
Can anyone give me tips in order to modify the proper entry?
Thanks

• Since, you have imported the LDIF file in the new AD, all the users in the original AD are created afresh in your AD environment. Thus, you would need to create a DNS naming service identical to the original one in your environment as the suffix to which you want to add the entry should exist in the database. Also, the domain admin credentials used in the original LDAP directory will be required to bind with the credentials of a user in imported LDIF file.
To do this, you would need to modify the domain admin credentials using the following commands. Below shown script is a sample on how to modify the domain admin credentials and then try to bind the user using those credentials.
Create a new LDIF file with the following contents: -
‘ dn: uid=XYZ,ou=Domain Administrators,dc=example,dc=com
cn: XYZ
sn: XYZ
givenName: XYZ
objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: inetOrgPerson
ou: Accounting
ou: People
l: Santa Clara
uid: XYZ
mail: XYZ#example.com
roomnumber: 5484
userpassword: Pass#123 ’
Then, add the entry using ‘ldapmodify’ with the ‘—defaultAdd’ option
‘ ldapmodify --hostname localhost --port 389 --bindDN "cn=Directory Manager" \
--bindPassword password --defaultAdd --filename /tmp/new.ldif ‘
With these commands, you would be able to modify the domain administrator credentials and then be able to bind the user in LDAP for sure. Just change the ldif file name with the one you have and change the entries in the ldif file with the actual ones from the original directory. Please find this link below for your reference: -
https://docs.oracle.com/cd/E22289_01/html/821-1273/adding-modifying-and-deleting-directory-data.html
While adding the password policy in the openldap file it throws error While running from the command line

adding new entry "cn=DefaultPPolicy,ou=Policies,dc=zariga,dc=com"

This is the LDIF file

You're trying to add an object to LDAP with only pwdPolicy objectClass which is defined as AUXILIARY (see Password Policy for LDAP Directories, ch. 5.1) and every object added to LDAP server must have a STRUCTURAL objectClass.
You need to change your LDIF file to include one STRUCTURAL objectClass like device (or any other that you fancy but it's type is STRUCTURAL).
For instance:
dn: cn=DefaultPPolicy,ou=Policies,dc=zariga,dc=com
cn: DefaultPPolicy
objectClass: device
objectClass: pwdPolicy
objectClass: top

I am using openldap 2.4. I have configured it with following configuration.

Also I added default password policy

But still admin is able to create users without these constraints. How will I confirm if my ppolicy overlay is working? How can I test if these constraint are actually been applied.?
The only user that is free from the password policy constraints is the internal rootdn user. You shouldn't use that yourself for anything. It is the user that slapd itself uses to update the DIT. You should define another admin user, in the DIT, with the necessary permissions. Using the rootdn user for admin tasks will bypass every constraint known to man.
To use the ppolicy fully, you have to use the password policy request control and check for the corresponding response control in your code so you can discover impending expiry, grace periods, etc.
You can test password policy with ldap* commands (OpenLDAP LDAP clients), which allow to use LDAP controls.
You must know a valid DN and a password (not rootdn, which override password policy).
For example:
clement#ader-xps:~$ ldapwhoami -x -H ldap://localhost -D uid=coudot,ou=users,dc=example,dc=com -W -e ppolicy
Enter LDAP Password:
ldap_bind: Invalid credentials (49); Account locked
I have a problem with connecting foswiki to ldap. I want to authenticate users against LDAP directory (as it is stated in the requirements of school seminar work ). But it doesn't work. When I try to login with my name already saved in LDAP, it just writes "Oops: we could not recognize you. Try again or reset your password.". I will be thankful for any help and I will provide any further information necessary.

Since your pasted foswiki configuration has been removed, I will try to answer to my best knowledge.
I am assuming you are using LdapContrib
Ensure your UserMappingManager is set to Foswiki::Users::LdapUserMapping.
Ensure your PasswordManager is set to something sensible, i.e. Foswiki::Users::LdapPasswduser
I am working with OpenLDAP and client browser as Apache directory Studio.
I did whatever required for enforcing ppolicies to the openLDAP users still I think its missing something and someware.
This is my ppolicy.ldif

still it allows to add userPassword from apache directory studio with more than 4 character.can anyone tell me why is it so? Thanks in advance .

The password policy overlay requires you not to carry out the operation as the rootDN. You should use an admin login defined in the DIT that has the appropriate permissions.
