Password History check in openldap not working when I am using SHA-256 password hashing in openldap.
So I am sending clear text password from my java application to openLDAP and it is storing as SHA-256 hashed form on its own.
whenever I am changing password, openLDAP is storing the previous password in pwdHistory.
There is no problem in that but when I am changing password with the same password previously used it is taking up without throwing any error.
I am struggling to make it work for few weeks. Please somebody help me.
My environment details:
OpenLDAP 2.4.38
RHEL 6
Following details also mentioned in slapd.conf
include ../etc/openldap/schema/ppolicy.schema
password-hash {SHA256}
overlay ppolicy
ppolicy_default "cn=default,ou=pwdpolicies,dc=my-domain,dc=com"
ppolicy_hash_cleartext
my password policy:
dn: cn=Default,ou=pwdpolicies,dc=my-domain,dc=com
objectClass: pwdPolicy
objectClass: person
objectClass: top
cn: Default
sn: Default
pwdAttribute: userPassword
pwdMinAge: 0
pwdInHistory: 5
pwdFailureCountInterval: 0
pwdLockout: TRUE
pwdLockoutDuration: 0
pwdAllowUserChange: TRUE
pwdExpireWarning: 0
pwdGraceAuthNLimit: 0
pwdMustChange: FALSE
pwdSafeModify: FALSE
Kindly let me know if I have to give me more information to nail down the issue. Please Please Please someone help me on this. I am badly need a solution on this.

I have configured OpenLDAP to store user information.
In Ping Federate, I have given the OpenLDAP connection information. LDAP connection has been established. I am using HTTP Basic adapter on the PF IDP side.
How to give search filter?I have given something like:
cn=$username.
The following is the User information in OpenLDAP directory server.
dn: cn=John Smith,ou=people,dc=highroads,dc=com
objectclass: inetOrgPerson
cn: John Smith
cn: John J Smith
sn: Smith
uid: jsmith
userpassword: jSmitH
ou: Sales
On single sign-on authentication, I gave:
Username : uid
Password : userpassword
from the user information in OpenLDAP directory. But I am not able to access SP resource.
Please let me know about the configuration information I should provide on the Ping Federate side.
Thanks,
Aswini J
You would manage this in your Password Credential Validator that you have assigned to the HTTP Basic Adapter. If the user is providing the attribute value stored in the "uid" attribute, then you would typically specify "uid=${username}" as the Search Filter and "dc=highroads,dc=com" as the Search Base for the PCV. You can make this more complex/specific as needed to ensure you only get a single user identity returned from your LDAP.
I am using openldap 2.4. I have configured it with following configuration.
include /etc/ldap/schema/core.schema
include /etc/ldap/schema/cosine.schema
include /etc/ldap/schema/nis.schema
include /etc/ldap/schema/inetorgperson.schema
include /etc/ldap/schema/HFSchema.schema
include /etc/ldap/schema/ppolicy.schema
pidfile /var/run/slapd/slapd.pid
modulepath /usr/lib/ldap
moduleload back_hdb.la
moduleload ppolicy.la
database hdb
suffix "dc=example,dc=com"
rootdn "cn=admin,dc=example,dc=com"
rootpw {SSHA}xzW0DfNFHahvm/C68ZR4YvbZGFQJjfz5
overlay ppolicy
ppolicy_default "cn=DefaultPwdPolicy,ou=Policies,dc=example,dc=com"
ppolicy_use_lockout
ppolicy_hash_cleartext
Also I added default password policy
# DefaultPwdPolicy, Policies, example.com
dn: cn=DefaultPwdPolicy,ou=Policies,dc=example,dc=com
cn: DefaultPwdPolicy
pwdAttribute: 2.5.4.35
objectClass: pwdPolicy
objectClass: top
objectClass: device
pwdAllowUserChange: TRUE
pwdMaxAge: 7776000
pwdInHistory: 5
pwdCheckQuality: 2
pwdMinLength: 8
pwdExpireWarning: 432000
pwdLockoutDuration: 900
pwdMaxFailure: 3
pwdMustChange: TRUE
pwdSafeModify: TRUE
pwdLockout: TRUE
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 configured LDAP server in my ubuntu 12.04 in the same server Cloudera core hadoop service installed . Here i want to integrate cloudera hue with LDAP server.

i use phpldapadmin to login my LDAP server which was working fine ..
My Login DN: cn=admin,dc=gmps,dc=com
I have configured this ldap server in Hue cloudera as
ldap_url : ldap://75.101.250.10
LDAP Username Pattern : "uid=admin,ou=admin,dc=greycampus,dc=com"
user_name_attr: admin
After this i restarted HUE and i just logged into HUE web UI there if click on
Hue ---> Manage Users ---> Sync LDAP users and groups --> Sync
i am not getting any users syced from LDAP server ..
if i click Add/Sync LDAP user .. then enter username and ok .. i am getting
There was an error when communicating with LDAP
{'info': 'invalid DN', 'desc': 'Invalid DN syntax'}
i dont know where i did wrong .. and its still confusing where i have supply my LDAP password .. and how hue communicate with LDAP without password .. kindly any one please help
I can't understand neither your LDAP configuration nor your Hue configuration.
firstly you define your LDAP root, dc=gmps,dc=com, ok.
Next, you define an admin role, which is definitly not a user, just a role.
dn: cn=admin,dc=gmps,dc=com
Finally you define a user, which doesn't seem to be linked to the admin role.
If you don't have any relation defined between a user and a role, it'll be difficult for hue to grant something to your user.
Next, about yourr Hue configuration:
The user should be a parameter of the pattern.
If a user DN is dn: cn=aaryan aditya,cn=students,ou=users,dc=gmps,dc=com, your pattern should be at least something like cn=
Hue webapp substitute by the typed login and make a first request to validate the authentification of your user (aka username/password against the LDAP user information).
To perform the search, you need to define the LDAP base search (dc=gmps,dc=com) and a bind user, authorized user DN to look into your LDAP (for instance, cn=aaryan aditya,cn=students,ou=users,dc=gmps,dc=com)
If you want to limit the global access to just a portion of your LDAP, you can specify an additional filter. When you'll define a relation between users and roles, you'll can restrict the access to the users by their roles.
You have to specify what's the attribute you're considerating to identify the user (in your case, it seems to be cn, so user_name_attr = cn)
To do the mapping between LDAP and Hue permissions, you have to tell Hue which roles are considerated, throw the group_filter. Next you have to specify the attribute of the role which allow to identify the role (in your case, it seems to be cn)
Finally, you have to tell to hue which attribute allows you to link a role to a user (which doesn't seem to be undefined in your configuration)
Next, restarting your cluster, everything should be ok. Syncing your users/group will load users and roles from your LDAP to Hue, next step will be configure each role in HUE to give it the expected permissions.
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 making some application in rails in which user needs to be log-in first to see the content. I used devise and ldap_devise_authenticatable to make user log-in through existing LDAP account.
However, when I tried to log in with my account into my application then log-in failure occurs(401 error unauthorized) even though I already have account on ldap.
I am following this tutorial
And following is the screenshot of my ldap server page:
I know the problem is in my ldap configuration file. How can i configure it properly so that my application send correct string to ldap server like in above screenshot
Code of my ldap.yml is as follows:
authorizations: &AUTHORIZATIONS
group_base: ou=groups,dc=test,dc=com
required_groups:
- cn=admins,ou=groups,dc=test,dc=com
- cn=users,ou=groups,dc=test,dc=com
- ["moreMembers", "cn=users,ou=groups,dc=test,dc=com"]
require_attribute:
objectClass: inetOrgPerson
authorizationRole: postsAdmin
## Environment
development:
host: 172.16.100.6
port: 389
attribute: cn
base: ou=People,dc=iitj,dc=ac,dc=in
#admin_user: cn=admin,dc=test,dc=com
#admin_password: admin_password
ssl: false
Have you tried setting attribute: sAMAccountName?
Also you need to set admin_ser and admin_password to match the credentials of the account you have in LDAP.
