You shouldn't use user1 as binddn in the application but a dedicated service account. And you should make sure that everyone is allowed to authenticate.
like so:
LDAP entry: cn=zabix,ou=applications,dc=prime,dc=ds,dc=geo,dc=com objectClass:... ... userPassword: password
Zabix configuration host: 192.168.1.1 base: ou=People,dc=prime,dc=ds,dc=geo,dc=com port: 636 uid: uid bind_dn: cn=zabix,ou=applications,dc=prime,dc=ds,dc=geo,dc=com password: password
ACL configuration:
access to dn.sub="ou=People,dc=prime,dc=ds,dc=geo,dc=com" attrs=userPassword by self write by * auth
access to dn.sub="ou=People,dc=prime,dc=ds,dc=geo,dc=com" filter="(allowedService=zabbix)" attrs=uid,objectClass by dn.exact="cn=zabix,ou=applications,dc=prime,dc=ds,dc=geo,dc=com" read by self read
Hope this works for you.
Cheers,
Peter

Dear Peter
As per your suggestion In inetOrgPerson I created a custom attribute called allowedService and now the users list is as
dn: ou=People,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: organizationalUnit ou: People
dn: uid=user1,ou=People,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: posixAccount objectClass: inetOrgPerson uid: user1 allowedService: zabbix allowedService: gitlab
dn: uid=user2,ou=People,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: posixAccount objectClass: inetOrgPerson uid: user2 allowedService: gitlab
dn: uid=user3,ou=People,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: posixAccount objectClass: inetOrgPerson uid: user3 allowedService: gitlab
Now we have two applications zabbix and gitlb. For zabbix user1 need to have access others not. For gitlab three users should have access.
We have created two organizational units as
dn: ou=zabix,ou=Groups,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: organizationalUnit ou: zabbix
dn: ou=gitlab,ou=Groups,dc=prime,dc=ds,dc=geo,dc=com objectClass: top objectClass: organizationalUnit ou: gitlab
In zabbix application configured as follows:
host: 192.168.1.1 base: ou=zabix,ou=Groups,dc=prime,dc=ds,dc=geo,dc=com port: 636 uid: uid bind_dn: uid=user1,ou=People,dc=prime,dc=ds,dc=geo,dc=com password: passwordIn slapd.conf file we added acl as:
access to dn.base="ou=People,dc=prime,dc=ds,dc=geo,dc=com" filter="(allowedService=zabbix)" attrs=uid,userPassword by dn.exact="ou=zabix,ou=Groups,dc=prime,dc=ds,dc=geo,dc=com" read by * break
But with this configuration we are unable to login to zabix application with user user1.
Can you please help me on it. Let me know I am following the correct way? Can you please update me the correct steps we need to done.
Thanks in advance. Geo Skype id: geopcgeo

Dear Peter Thanks for your update. As you specified I am trying to set up this option. Thanks again Geo.

Frankly I don't quite understand how you would like to use that. What you should do as I proposed (solution 2b.): define an attribute like allowedService and manage that instead of using groups. create accounts for each application (all applications have binddn and bind password to connect to an ldap server) And the restrict access rights of these DNs via ACLs such as : access to filter=(allowedService=Wordpress) by cn=wordpress,ou=serviceaccounts,dc=examle,dc=com read ... access to * by * none Cheers, Peter Am 07.05.2013 14:59, schrieb Geo P.C.:Dear Peter, Thanks for your reply. In order to login to an application from a selected group only we checked alias option. But it was not working. Please see the details: In application we have given base dn as ou=People,dc=geo,dc=com and the user dn: uid=geo_pc,ou=People,dc=geo,dc=com can able to login to the application successfully. Now we created an alias as follows: dn: uid=geo_pc,ou=Applications,ou=Groups,dc=geo,dc=com aliasedobjectname: uid=geo_pc,ou=People,dc=geo,dc=com objectclass: alias objectclass: extensibleObject objectclass: top uid: geo_pc Now in application we have given base dn as ou=Applications,ou=Groups,dc=geo,dc=com but with this user ou=Applications,ou=Groups,dc=geo,dc=com we are unable to login to the application.

If you had a config parameter like search filter in your application you could use that to make unwanted users invisible for the application. But this means you can't use group entries , but dynamic groups, i.e. a group is an ldapfilter, e.g. "(allowedServices=Wordpress)" and you manage group privileges in an own attribute allowedServices. 2.) You could also do this via ACLs in the server, each application using its own bind dn, which can then have read access to a subset of the data. Here you can use a.) group entries or b.) dynamic groups 3.) Of course you could also have a separate replica for each application with filtered entries, but only with dynamic groups (see 1.), but that is a lot of overhead. Beware: combining this with 2. i.e. group ACLs on replica bindDN is a rathole, don't do that! 4.) IMHO best would be to file a feature request to the application developers for supporting LDAP-groups if not 4.) my recommendation would be 2a.) being the minimal invasive alternative.

These application support LDAP but not group based authentication. Please let us know is there any option to restrict selected users to login. We created all users under ou ‘users’ . Inline image 1 On these application we need to login certain users only. How we can restrict it as we can’t able to restrict on application side In these application they provide only “Base DN” and “Search Attribute” so we can’t able to give dn: ou=users,ou=system as it gives access to all users. So is it possible to give Base DN as “cn=Zabbix,ou=groups,ou=system” and this group contains only user1 and user2. SO it will restrict users. Please let us know how we can implement this scenario.
