How to use OpenLDAP members groups
-
I am experimenting with OpenLDAP because i want to learn working with it.
I though it would be great of i could use it with pfSense for different groups of users giving them access to different things like vpn, radius, web login etc.What i have at the moment is a working OpenLDAP server with several users and groups i assigned the users to.
The group show up wen i do a test authentication with pfSense but i don't know how i can use for example the vpnusers group for my OpenVPN server and the users group for something else.Can somebody with experience of OpenLDAP and pfSense explain how to do this?
I am a total newbie with LDAP.

You need to create user groups in pfSense with identical names. Then you can assign permissions to those groups and users authenticating with LDAP will inherit them if they are a member.

That is what i did create equal user groups thats why they show up wen i test the users the groups users and vpnusers are picked up as you can see in the image.
The thing i mis is how can i connect the vpnusers group to the openvpn server.
I have to set the ldap database ofcourse but only users in the ou=People,dc=domain,dc=org group is working wen i use the openvpn server.
It does nothing with the users or vpnusers group. -
What permissions did you set on those groups?
-
-
btw when i remove those "Assigned Privileges" i can still succesful test the ldap users with Diagnostics > Authentication
-
The authentication test itself would still work when logged in as another user.
What exactly are you seeing happen in testing?
-
In the tests i am doing in the above posts is logged in as admin and i test normal users i have created in ou=People,dc=domain,dc=org.
Then i created:
cn=users,ou=groups,dc=domain,dc=org
cn=vpnusers,ou=groups,dc=domain,dc=orgAnd added the test users, i created in ou:People, into those users and vpnusers groups as members.
-
What i would like to do is using cn=users for example to login a captive-portal and the cn=vpnusers vor login openvpn server.
-
But how are you testing the accounts? Trying to use them to log into the VPN and they fail?
Captive portal users would need to inherit the 'Services: Captive Portal Login' privilege.
-
I test the user accounts with Diagnostics > Authentication.
Only the users in ou=people work and at the same time recognizes membership of other groups, as you could see in the image above.
Then i also test with openvpn server in pfsense that also only works with the ou=people,dc=domain,dc=org users.What i would like is the OpenVPN server to use cn=vpnusers,ou=groups,dc=domain,dc=org members as OpenVPN users.
When i configure cn=vpnusers,ou=groups,dc=domain,dc=org as only option in "Authentication containers" in the LDAP auth server settings then authenticating is not working anymore.Somehow i should be able to configure pfsense ldap auth server to only use user members in cn=vpnusers,ou=groups,dc=domain,dc=org.

Ah I see. OK how is the LDAP server setup in pfSense?
-
I made a screenshot of it but had to zoom out to have everything in one image.
Hopefully you can read the settings.
-
Ok so that's the ou=People server. Do you have a separate server defined for ou=Users? Or are you changing that one?
-
No i have one OpenLDAP server with one DIT.
I don't have a ou=users i only have ou=groups and ou=people.In ou=groups i created cn=users and cn=vpnusers and added the ou=people users to those groups as memberUid.
For me this is all totally new so probably i do all kinds of stupid things.
I want to learn how to manage a OpenLDAP directory and i thought connecting it to pfSense would be a good little learning project.

You need to have 'Groups' selected there to authenticate users from that.
-
I tested all that several times.
If i only select ou=groups,dc=domain,dc=orgI get ...
If i select all 3 of the options then pfSense picks only the ou=people,dc=domain,dc=org and authenticating is succesful but then those cn=users and cn=vpnusers are not used.
I want only authenticate against cn=vpnusers,ou=group,dc=domain,dc=org
If i only select that option i again get ...
The only way to get a successful authentication is against the users in ou=groups,dc=domain,dc=org
I tried many different settings today i found online.
Only that second option works,
But then i cannot use different member groups only the users that are in ou=peopleI did'nt know what to try next so i thought i try netgate forums.
-
Hmm, odd. I'd expect those two ous to behave the same. I can see why it would be a problem if you have both selected and the same users in each.
Slightly confused though because you seem to say above that selecting only ou=groups,dc=domain,dc=org both fails and is the only way to successfully authenticate?
-
Sorry if i am a bit confusing in the above posts.
I try to be more clear.
English is not my main language so i do my best
As you can see on the pictures i only have 2 OUs People and Groups.
I created 2 normal and 1 admin users in ou=People.Then i created 3 groups in ou=Groups.
My plan is to use those CN groups (in ou=groups) to authorize several services to the users by adding the users to one or more of those cn groups (cn=users & cn=vpnusers & cn=admins).
As an example i added users to the cn=vpnusers so i could give them access to de pfSense OpenVPN server.
And the admin user i added to the cn=admins group to give him/them admin access to pfSense.But those groups under ou=Groups ar not selectable / configurable in pfSense or not that i know off how to do that.
Only ou=People,dc=domain,dc=org is successful authenticating in "Diagnostics / Authentication" and the OpenVPN server.
It doesn't matter of i enable or disable the other containers (cn=users / cn=vpnusers) they don't work.
I added different users to those cn groups to test them separately so i know for sure which one does or doesn't work and both don't work.Although the cn=users and cn=vpnusers is seen by pfSense as you can see in one of the images from earlier i can not do anything with them like configure OpenVPN server to use for example the cn=vpnusers to authenticate a member user of that group. Or i just don't know yet how to do that.
Just like "Diagnostics / Authentication" also OpenVPN server works successfully with users in ou=People,dc=domain,dc=org.
cn=users,ou=Groups,dc=domain,dc=org or cn=vpnusers,ou=Groups,dc=domain,dc=org does not work.Or wel maybe it does and i just don't know jet how to do it, how to configure it.
That is what i hope to learn.
