I'm trying to configure Nexus 3.42.0-01 with OpenLDAP.
I set the configuration as below:
LDAP server address: ldaps://192.168.0.1:636
Search Base DN: dc=my,dc=domain,dc=local
Authentication Method: Simple Authentication
Username: uid=appauth,ou=auth,ou=nexus_cicd,ou=Applications,dc=my,dc=domain,dc=local
Password: ********
User relative DN: <blank>
User subtree: <checked>
Object Class: inetOrgPerson
User filter: <blank>
User ID attribute: uid
Real name attribute: cn
Email attribute: mail
Map LDAP groups roles: <checked>
Group type: Dynamic Groups
Group member of attribute: memberOf
I can view all users, but my problem is how can I restrict access to only users of a specific group?
Thanks for your support.
It depends on your needs, and how you define "restrict access".
You can create an external role mapping (only) for that specific group, role for which you can assign the privileges you want, and the restricted users that are not member of that group would get the role 'anonymous'.
Or, if you don't want the restricted users to appear at all in Nexus and/or if they shouldn't authenticate, you can just use a filter to exclude them, eg.
User filter: (memberOf=<groupDN>)
Optionally, you could also refine the base search eg.
User relative DN: ou=Users
.. but this will probably not be sufficient to apply the restriction.

I installed Openldap in server and after that added the user into the ldap,below screen show show the added user through Apache Active Directory
Now in keycloak i added user federation as a openLdap and its connecting to ldap without any issue,but when i am trying to sync the user i am getting message
Success! Sync of users finished successfully. 0 imported users, 0
updated users
So no user import from ldap to keycloak ,below is the related ldap connection information in keycloak .
Thanks to #EricLavault and one of company colleague at last Keycloak able to import the user successfully. Below changes i have done to fix the issue.
Change the User Object Classes=*
Created a new entry ou=People then created user under it
In Keycloak used Users DN = ou=user,ou=people,dc=suredev20
After this its start throwing below exception
ERROR [org.keycloak.storage.ldap.LDAPStorageProviderFactory] (default
task-1931) Failed during import user from LDAP:
org.keycloak.models.ModelException: User returned from LDAP has null
username! Check configuration of your LDAP mappings. Mapped username
LDAP attribute: uid, user DN:
cn=subodh123,ou=user,ou=People,dc=suredev20, attributes from LDAP:
{sn=[joshi123], cn=[subodh123], createTimestamp=[20191118180647Z],
modifyTimestamp=[20191118180647Z]}
Which is fixed by using Username LDAP attribute = cn as ldap username Attribute description in openldap case bydefault cn
User entries are not stored correctly in your directory. In fact you shouldn't use cn=root as a container as it's supposed to represent the directory manager and should be used for binding and other operations but not for structuring your directory.
Instead, you should use the default user container (at least for OpenLDAP and Apache DS) that is ou=people,dc=suredev20, ie. you need to move cn=subodh
from cn=subodh,ou=user,cn=root,dc=suredev
to cn=subodh,ou=people,dc=suredev20
Also, in Keycloack you need to set users dn accordingly : ou=people,dc=suredev20
(you can try with ou=user,cn=root,dc=suredev without moving subodh entry but not recommended).
I currently try to configure Discourse to only allow users in a specific ldap group to log in. Discourse has a plugin called discourse-ldap auth ( https://github.com/jonmbake/discourse-ldap-auth ). This plugin uses the omniauth ldap module: https://github.com/omniauth/omniauth-ldap
My discourse plugin configuration (the configuration is actually used by the discourse plugin for the omniauth ldap module):
ldap enabled: true
ldap hostname: the hostname of my ldap server
ldap port: 389
ldap method: plain
ldap base: the base of my ldap server
ldap uid: userPrincipalName
ldap bind dn: Nothing
ldap password: Nothing
ldap filter: (&(userPrincipalName=%{username})(memberOf=cn=[the name of the required group],ou=....,[base]))
When using this configuration, nobody can log in to the forum. When I use the bind dn and password, everybody can log in.
I also tried this filter without success (copied from my ldap servers filter):
(&(&(&(userPrincipalName=%{username})(memberOf=[dn of the group]))))
What do I have to configure, to only allow users in that specific group to log in?
I didn't found any errors or indicators in the log. Please help!
Thanks fou your help and attention!
You do need the "ldap dn" and "ldap password". Those are the credentials used to authenticate to LDAP so you can lookup people's accounts. Usually, that is a service account only used by your application.
The filter should probably look something like this:
(&(sAMAccountName=%{username})(memberOf:1.2.840.113556.1.4.1941:=[dn of the group]))
Users will usually log in with the sAMAccountName, which is usually called just the "username". Whenever you see an account in the DOMAIN\username format, that username is the sAMAccountName.
The userPrincipalName is usually in the format of username#domain.com. It is sometimes the same as the email address, but it doesn't have to be.
The crazy number I put in that query tells Active Directory to search recursively through groups. So that would allow you to put groups into your authentication group, and members of that new group would be given access to your application too. Without that, only direct members of that group will have access.
I am trying to integrate LDAP Active Directory with Keycloak. I have been able to synchronize LDAP users using Custom User LDAP Filter that filters by LDAP attributes - (theAttribute=theValue). Is there a way/syntax to filter by groups? For example, say I have Active Directory group "My Group" and I want to synchronize to Keycloak only users in that group. What would be the search Custom User LDAP Filter?
How about memberOf? For example:
(&(objectCategory=Person)(sAMAccountName=*)(theAttribute=theValue)(memberOf=cn=My Group,dc=example,dc=com))
Please refer to RFC2254 "The String Representation of LDAP Search Filters" more details:
I´m trying to configure my Nexus instance, 2.11, to integrate with LDAP, OpenLDAP, with SSL.
It appears to work with the settings bellow:
Connection Protocol: ldaps Hostname: mydomain.local Port: 636 Search Base: dc=mydomain,dc=local
Authentication Auth. Method: Simple Authentication SASL Realm: Username: dc=admi,dc=mydomain,dc=local
Password: MySuperSecretPassword
When I click on Check Authentication it returns:
LDAP connection and authentication test completed Successfully.
Then in sections:
User element Mapping Base DN: ou=users User subtree: (but it doesn´t appear to affect something) Object
class: inetOrgPerson User filter: User UD Attribute:
uid Real Name Attribute: cn E-Mail Attribute: mail
Password Attribute: Group Element Mapping
Then clicking on Check User Mapping, it return all the users on LDAP directory.
It´s good, but... When I´m trying to Log-In with any user, it returns:
Incorrect username, password or no permission to use Nexus User
Interface. Try again. Please login before attempting further requests.
I´d try to mapp a user from LDAP, in User Manegement interface, and give this user a Nexus Administrator Rule, I tried to put all roles to this user, but always get the same error above.
Is there any other configuration nedded to make it work?
Thanks!
In the administration sidebar, click 'server'
Enable "OSS LDAP Authentication Realm" in the security realm.
There is a feature request to make this more visible.

I have Jira 5.x locally installed and an OpenLDAP Server with Users and Groups. The Syncronisation in Jira get all users and groups perfectly, but the users do not belong to any group. I've set the default groups to enable LDAP users to login to Jira.
What am I doing wrong?
This is the LDAP Schema:
dn: uid=demo.user#domain.com,ou=intern,ou=people,dc=company,dc=local
objectClass: posixAccount
objectClass: account
objectClass: ldapPublicKey
homeDirectory: /home/demouser
loginShell: /bin/bash
cn: Demo User
uidNumber: 10001
gidNumber: 10001
userPassword: {SSHA}xxxxxxxxxxx
uid: demo.user#domain.com
dn: cn=groupname,ou=project,ou=group,dc=company,dc=local
objectClass: posixGroup
description: a funny group for a project
gidNumber: 10018
cn: groupname
memberUid: demo.user#domain.com
memberUid: xyz
memberUid: ...
If I run the Test in Jira, I'm getting the following error Message:
Test get user's memberships with 0 groups retrieved. : Failed
And these are the Settings in Jira:
We experienced a similar problem. It seemed that JIRA insists on including the User Membership Attribute - which is from the user schema - such as "memberOf" regardless of whether you already have the Group Members Attribute. However it should be an either / or option - either Group Membership Attribute (eg. memberUid in the group schema) OR User Membership Attribute (eg. memberOf in the user schema), as they fulfill more or less the same function.
The problem was solved when we noticed there are actually two closely related options for the directory type: "OpenLDAP" and "OpenLDAP (Read-only Posix Schema)". As we were using the posixGroup schema (as in your example), choosing the Read-only Posix Schema solved the issue. If you go to the Server Settings section at the top, you should see both options in the drop down list.
In addition, you should be able to switch from "Read Only, with Local Groups" to "Read Only" in the LDAP Permissions section (if you wanted to). One caveat is that we were using the inetOrgPerson and shadowAccount schemas (rather than account, as in your example) in conjunction with posixAccount for the user schemas.
