Sorry but it doesn't accept "hi everyone "
I have several apps which are authenticated by ldap. can keycloack replace this authentication with ldap? and in this way I do not touch to the configuration Of applications ?
Thank you
You can read this article https://wjw465150.gitbooks.io/keycloak-documentation/content/server_admin/topics/user-federation/ldap.html
By default Keycloack copy your ldap data but you can choose keycloack use your ldap data :
By default, Keycloak will import users from LDAP into the local Keycloak user database. This copy of the user is either synchronized on demand, or through a periodic background task. The one exception to this is passwords. Passwords are not imported and password validation is delegated to the LDAP server. The benefits to this approach is that all Keycloak features will work as any extra per-user data that is needed can be stored locally. This approach also reduces load on the LDAP server as uncached users are loaded from the Keycloak database the 2nd time they are accessed. The only load your LDAP server will have is password validation. The downside to this approach is that when a user is first queried, this will require a Keycloak database insert. The import will also have to be synchronized with your LDAP server as needed.
Alternatively, you can choose not to import users into the Keycloak user database. In this case, the common user model that the Keycloak runtime uses is backed only by the LDAP server. This means that if LDAP doesn’t support a piece of data that a Keycloak feature needs that feature will not work. The benefit to this approach is that you do not have the overhead of importing and synchronizing a copy of the LDAP user into the Keycloak user database

Is it possible to manage the password by keycloak with federated users? I have users
federated from external database and currently also the password is being checked from the external database.
Is there a possibility to register a password in keycloak for the user just after that user is created in the external database and then federated to keycloak?
My motivation is having the built in password reset functionality of keycloak not building extra SPI code for this on federated users.
It is not really clear from your question, but since you have federated users from an external database, I assume you have implemented your custom UserStorageProvider. You are also validating passwords against your external database. So, I assume you have also implemented CredentialInputValidator interface. If you have not implemented CredentialInputUpdater, I would assume what you are trying to achieve should work out of the box.
If you have implemented CredentialInputUpdater, you could try to do the following:
Within you implementation of CredentialInputValidator.isvalid first check if the user has a local password configured, e.g. like this
keycloakSession.userCredentialManager().isConfiguredLocally(realm, user, credentialInput.getType())
If this is the case (returns true), simply have isValid return false. In this case Keycloak should use other CredentialInputValidators and check for the locally configured password.
If this is not the case (returns false), do the password check against your external database. Iff the password is valid, silently migrate the password to Keycloak's local credential store. This could look something similar to this:
CredentialProvider passwordProvider = keycloakSession.getProvider(CredentialProvider.class, PasswordCredentialProviderFactory.PROVIDER_ID);
if (passwordProvider instanceof CredentialInputUpdater) {
((CredentialInputUpdater) passwordProvider).updateCredential(realm, user, credentialInput);
}
Within CredentialInputUpdater.updateCredential make sure to update the local store in addition to the password in your database.
Now your user's passwords will be stored in Keycloak's local database / credential store and the built in password reset functionality should work as expected.
Is there a possibility to register a passward in keycloak for the user
just after the user is created in external database and then federated
to keycloak?
From the Keycloak Documentation itself:
By default, Keycloak will import users from LDAP into the local
Keycloak user database. This copy of the user is either synchronized
on demand, or through a periodic background task. The single exception
to this is the synchronization of passwords. Passwords are never
imported. Their validation is always delegated to the LDAP server. The
benefits of this approach is that all Keycloak features will work as
any extra per-user data that is needed can be stored locally. The
downside of this approach is that each time that a specific user is
queried for the first time, a corresponding Keycloak database insert
is performed.
So, im doing research to know if its a good alternative to implement keycloak on the environment i'm working at.
Im using LDAP to manage users at my workingplace. I was wondering if is there a way to use keycloak as auth service in all upcoming systems and some of the existing ones. We are currently managing it with an IDP that we need to improve or replace, also there are some systems use their own login (this will eventually change).
The main problem i've crossed is that keycloak synchronizes against ldap and i dont want user data to be stored on keycloak, maybe if its only login data. User data is planned to be kept only on ldap's database in case that any userdata needs to be updated.
So is there a way to use keycloak only as an auth service fetching user credentials from ldap on every auth request?
pd: maybe i am mistaken on the meaning of what's an auth service an whats an IDP.
Actually it is not necessary that LDAP users are synced to Keycloak.
Keycloak supports both options
Importing and optionally syncing users from LDAP to Keycloak
or
Always getting the User info from LDAP directly.
But keycloak will always generate some basic federated user in it's database (e.g. for keeping up a session when using OpenID Connect - but you should not really care about that).
As far as I know (but I've not used that myself) you could also use keycloak to maintain the LDAP users data and write changes back to LDAP (see "Edit Mode" in Keycloak documentation)
Check Keycloak documentation regarding LDAP stuff to get more information https://www.keycloak.org/docs/6.0/server_admin/#_ldap
Beside the User-Data Topic, Keycloak provides a lot of different Protocols (like SAML and OpenIDConnect) to provide authentication for your services. So you could use different/multiple authentication protocols depending on your applications with just one "LDAP-Backend"
I am creating a login page with an authentication using LDAP. I could see LDAP3 packages for flask with login forms as well. I am looking for a form where the developer of the portal(say me or anyone in our team) should not be able to add any print statements and sniff the username and password when someone log in...
The flask form is exposing the password variable as a plain string. Even if it doesn't expose , it is possible to put a print statement in the flask_form validate function.
Is there any option available like the form is bundled as binary or c-python module where the developer has no option to sniff the credentials at all..
If not possible or no options available as they know off, any other framework like django helps for these usecase?
By design, server-side LDAP authentication requires the server receive the username & password from the user and relay that information to the LDAP server. This means a developer could insert a line that logs all credentials out somewhere, grab the passwords from process traces, dump memory, etc. If you don't want any of the developers or system administrators to have access to user passwords, use some type of federated authentication instead of LDAP.
In a federated authentication scheme, the user auths against some other source (e.g. ADFS) and your app checks a token that essentially says "this trusted other auth source says the person is Lisa".
I am trying to protect a Java servlet with OpenAM + J2EE tomcat agent. I got this part working by using embedded OpenDJ of OpenAM.
Now I am trying to authenticate against a LDAP server, so I added a LDAP module instance for OpenAM, but I get "User has no profile in this organization" when I am trying use uid/password of an user from that LDAP store.
I checked OpenAM administration guide on this the description is rather brief. I am wondering if it is even possible to do this without using the data store configured for OpenAM?
The login process in OpenAM is made of two stages:
Verifying credentials based on the authentication chain and individual authentication module configurations
User profile lookup
By configuring the LDAP authentication module you took care of the authentication part, however the profile lookup fails as you haven't configured the user data store (see data stores tab). Having a configured data store allows you to potentially expose additional user details across your deployment (e.g. include user attributes in SAML assertions or map them to HTTP headers with the agent), so in most of the scenarios having a data store configured is necessary.
In case you still don't want to configure a data store, then you can prevent the user profile lookup failure by going to Access Control -> <realm> -> Authentication -> All Core Settings -> User Profile Mode and set it to Ignore.
This is unrelated to authentication but it's related to authorization ... you have to configure appropriate policies ... see OpenAM docs.
Agents will enforce authorization, OpenAM determines if the user has the permission to access a protected resource.
As Bernhard has indicated authentication is only part of the process of granting access to a user. He is referring to using a Policy to control access.
Another method is to check if the authenticated user is a member of the desired group programmatically. This can be useful when you want access control over resources that OpenAM doesn't know about (e.g. specific data).
For example, lets say that you want different groups to have access to different rows in a table in a database. You can retrieve the group information associated with the user and add that to your database query, thus restricting the data returned.
I'm sure that you could do this with OpenAM as well using custom modules to allow the policy to use information in the database as resource, but I've found it is much simpler to perform this fine grained access control in your code, and is in all likelihood significantly faster.
I have a database with LDAP login enabled. It works fine when logging in through the PIA or when logging into app-designer through the application server.
I need to make app-designer allow me to login with 2-tier mode using LDAP authentication. Is this possible without customization?
I do not think this is possible. 2-tier logs directly into the database and more importantly, does not run the signon peoplecode that does call-outs for LDAP authentication. In fact, 2-tier is really just a Win32 app that runs no peoplecode - it isn't a peoplesoft "application." There is a user callout dll delivered with peoplesoft, and some scant documents on what you have to do to use it - but again, likely not going to meet your need. You may need to use the ldap synch online app engine job to pull in your ldap users to security tables if you want to use those login identities for 2-tier access.
The only delivered way to use LDAP Authentication for App Designer is to use connection 3-Tier through the app server. Only with the 3-Tier connection will the Signon PeopleCode be executed. With 2-Tier, there is no hook to the LDAP Server.
You could look at using the Grey Sparling Desktop Single Signon, which does integrate with App Designer and uses Windows and NTLM to grab Active Directory authentication. This would give you some degree of LDAP Authentication if you Windows machine authenticates with a domain. But it is an add-on product you would need to purchase.
Otherwise, as Epictetus mentioned, you can use the LDAP Username if you have it synced with your PeopleSoft database and use the local password stored in PSOPRDEFN.
One problem I have seen is that when using LDAP and 2 tier when you login with LDAP it somehow decrypts the password in PSOPRDEFN. The next login 2 tier by that same account throws the error cannot login please encrypt password using data movoer encrypt password *. If you encrypt that users password the same results happen following that users next LDAP login.
