"LDAP Account Unit" Username - What AD permissions?

[Matthew81]

Hi all,

we have an "LDAP Account Unit" object, and in this object we have two AD servers. And this AD servers has a username in the properties:

At the moment this account has very high permissions in the AD.

But we want to decrease the permissions, so we need to know what roles this user needs.

I can't find anything in the documentations etc.

So i hope you can help me here.

Many thanks.

Best regards
Matt

hy, 

I would say we need more details, like why or for what you use that AD account .

Were/are you with "AD Query" implemented on the Checkpoint ?

We're using CheckPoint Identity with Identity Collector and the account used in IC set-up and in the LDAP objects has only ad read and AD log read writes. (there is an SK that explain the rights, I'll check and come back)

Ty,

Mainly we use Identity Agents and Identity Collector:

The users have the ability to change their AD password with the Check Point Endpoint client if the password needs to be renewed. But i don't know if this is done by that user or if there is a different user managing the password change.

@Timothy_Hall gave you the sk I was thinking of as well, though I will say this. I was on the phone with customer once going through that sk and we spent literally 3 hours on the line with TAC without any success. Eventually, we made it work few days later, but did not last long, so we just gave up on it.

@Matthew81  password change via MOB or VPN client will be done with the expired users credentials, not with the user from the ldap account unit. With the old Smartdashboard you could walk through the AD via LDAP and change the values of every AD object. To do such changes your ldap account unit user needs write rights. I think with newer Smartconsole GUI these feature is not available. And I would prefer to change anything in AD with ADs own management tools.

Short answer is that it can be a Domain Administrator, but read only.

Long answer is that you can take a regular domain user and grant it the bare minimum privileges it needs for AD Query to function.  See here: sk93938: Using Identity Awareness AD Query without Active Directory Administrator privileges on Wind...

If you’re using a Windows Server with the latest patches and using ADQuery, you need to use a full admin user.
However, that’s only for the WMI portion, pretty sure for LDAP you only need read only permissions to the directory.

Does a regular user with read permissions on the LDAP tree suffice for lets say, AD groups reading and VPN authentication?

[Wolfgang]

Yes.

By the way, as this is CP official recommendation and I will also tell you, its super EASY to set up, if you can go with identity collector, I recommend it 100%, Im positive you will like it much better.

Happy to show you basics of it in my lab if you like.

Also, even though its not mentioned in the sk, but you can easily install the software on windows 10 and 11, works with no issues, though maybe I would not in production, as its not officially stated as supported : - )

[Matthew81]

Thank you all.

We will try with read only and see what happens 🙂

Having migrated to Identity Collectors (BTW that sk above doesn't seem to exist anymore) and it is working perfectly. The LDAP account unit is still in the configuration on the gateway object (Identity Collector --> Authentication settings). Is this account used by the gateway to retrieve user info and/or roles ? I suppose the Identity Collectors are responsable for this ?

How do I check if the account is actually retrieving the correct user info if i.e. a new server (Domain Controller) is added ?

Identity Collector only collects usernames from the configured AD servers.
Gateways use LDAP to query for the group, which must be configured with the relevant AD servers.
See: https://support.checkpoint.com/results/sk/sk113747 (LDAP setps also applicable for Identity Collector)

Thanks Dameon. My assumptions confirmed.
