I have an Ldap directory synchronised from a microsoft active directory.
This Ldap contain many account, each account have a password attribute.
I must develop a java program where a user have to log with his AD login and password, but i don't know the method employed to correctly encrypt the password typed.
I need it to compare with the ldap password.
I also need to bind new account with the same password encryption.
Anyone know how to do?
Well first of all you can use a BIND with SSL, but that's considered kind of the lame way to go about it and may be disabled on some systems. A truly secure way is using SPNEGO-GSS, and this is not trivial. You have to learn and understand about Kerberos. That's a long topic but you can start with reading and going through everything here
I've found the solution with spring,
here the method to test login/pass couple :
AndFilter filter = new AndFilter();
filter.and(new EqualsFilter("objectclass", "person")).and(new EqualsFilter("cn", login));
boolean authentifie = ldapTemplate.authenticate(DistinguishedName.EMPTY_PATH, filter.toString(), password);

I can create user using Boomi without any SSL(means using port389) and password(for new user to login) but I want to change user's phone number, and I got this error:

and I googled this error means:
Indicates that the LDAP server cannot process the request because of server-defined restrictions. This error is returned for the following reasons:
1. The add entry request violates the server's structure rules
2. The modify attribute request specifies attributes that users cannot modify -> I just want to change phone number.
3. Password restrictions prevent the action
4. Connection restrictions prevent the action. -> I think I can create user, so the connection is fine!
If LDAP error Code 53 means I need to do everything with "SSL", why I can create a user? How can I sort this problem out?
It's possible the user actually hasn't been properly provisioned. Maybe it's been created, but the account is not enabled because the password is invalid. Run an LDAP client and try and logon as the new user with the credentials that you supplied. Does it work?
Two suggestions:
Please use LDAPS if you're creating users/setting passwords, or basically anything in AD LDAP. There's no excuse not to these days, and Microsoft is in the process of deprecating plain LDAP from non-Windows clients, so you might as well do it now. All you need is to install/trust the issuing CA certificate chain (root and intermediate certs) for whatever CA is signing the DC's LDAPS certificate. You do not need to install any client LDAP cert.
Check the password policy of the target domain and ensure the passwords you are trying to set meet the requirements in terms of complexity, length and so on.
I am trying to implement a feature for a user to change their password in their settings page when they are logged in, and I require the user's old password as well as the new password when they try to change it as an extra security measure. My problem is that I cannot find a way to verify if the user's old password is correct. Is there an easy way to do this?
I receive the entered form inputs on the server so the solution would have to be on the backend (node.js)
Many thanks
Though the accepted solution works, there is also a way to verify a user's password from the backend, using the Google Identity Kit REST API's "verifyPassword" endpoint (which has recently been renamed to "signInWithPassword", but works exactly the same):
HTTP POST https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=[YOUR_FIREBASE_API_KEY]
{
email,
password,
}
If that endpoint doesn't return an error, that means the password is valid.
See this thread for more information.
You have to do it client side. This is not an operation that the admin SDK is designed to handle. You will ask the current user for the password and reauthenticate with it and then update password:
const cred = firebase.auth.EmailAuthProvider.credential(
firebase.auth().currentUser.email, oldPass);
firebase.auth().currentUser.reauthenticateWithCredential(cred)
.then(() => {
return firebase.auth().currentUser.updatePassword(newPass);
})
.catch((error) => {
// Some error.
});
I am having a hard time trying to figure out how to use Amazon Cognito in my web app (Java based). I want to have some kind of authentication hub (Amazon Cognito) to authenticate user with multiple Auth Providers - that's why I want to use Amazon Cognito! :)
Firstly, I set up User Pool (I have my UserPoolId: eu-central-1_xxxxxxxxxx) and created there one user. Next I created Identity Pool with IdentityPoolId (eu-central-1:yyyyyyyyyy). Then I authenticate with AWS JavaScript SDK to UserPool to get idToken and it working quite fine! I receive idToken from Cognito UserPool. Then I am sending this idToken to my backend app (Java based) and there I want to validate this idToken with IdentityPool. I added new Authentication Provider - Cognito with UserPoolId and newly created id of an App that I added in UserPool. I tried to follow with this tutorial:
https://aws.amazon.com/blogs/mobile/use-amazon-cognito-in-your-website-for-simple-aws-authentication/
But everytime I make
GetID
request I recevied Exception with
com.amazonaws.services.cognitoidentity.model.NotAuthorizedException: Token is not from a supported provider of this identity pool.
My Java code is below:
final AmazonCognitoIdentityClient identityClient = new AmazonCognitoIdentityClient(
new BasicAWSCredentials("accessKey", "secretKey"));
identityClient.setRegion(Region.getRegion(Regions.EU_CENTRAL_1));
GetIdRequest idRequest = new GetIdRequest();
idRequest.setAccountId("accountId");
idRequest.setIdentityPoolId(identityPoolId);
final String providerName = "cognito-idp.eu-central-1.amazonaws.com/eu-central-1_xxxxxxxx";
Map providerTokens = new HashMap();
providerTokens.put(providerName, idToken);
idRequest.setLogins(providerTokens);
GetIdResult idResp = identityClient.getId(idRequest);
Does anyone could help me with this task? Maybe I am doing something wrong?
Thanks,
Kamil :)
There are three pieces of data that need to match in this scenario:
Provider as configured in AWS.
Provider as put into the Logins map.
iss value (issuer) in the id token.
When I have seen this error, it has been because the value in the Logins map does not match the provider as configured in AWS.
For example, an unexpected port number or trailing slash can cause these not to match.
Beyond this, there are a couple of settings in AWS that need to line up.
Provider as configured in AWS
With a Cognito User Pool, Amazon configures this name for you, so it's non-configurable on the backend. The format of the providerName in your Java code looks good, but first I'd triple check the xxxxxxx part for a typo.
App Client settings
Then, make sure your App Client has Cognito enabled in your User Pool settings:
Federated Identities settings
Next, in your federated identities settings, verify that the user pool id and client id appear in the Cognito tab under "Authentication providers", and that they match your user pool and App Client.
JWT issuer
Finally, I would expect the error to be "Invalid login token. Issuer doesn't match providerName" if there was a problem with the iss value in the JWT. However, decoding the id token you get back and inspecting the contents (as suggested in another answer) is also good advice.
If all these pieces appear to be in place, and the error persists, please leave a comment. Happy Hacking!
When you created your user pool double check you have all the expected federated providers supported. If you use developer authenticated make sure you add that 'login....' domain as well.
Grab your/a token and look at it in jwt.io for clues as well.
I am designing an application where once user logged in, he can change the password.
For changing password, I need 3 details:
Old Password
New Password
Confirm Password
In servlet layer I am setting
user.setPassword(oldPassword);
method I am implementing in DAO layer
changePassword(User user, String newPassword)
The problem I am facing is that I am not able to validate old password.
Whatever the old password is, I am able to change to a new one.
I think what the problem might be is that it is taking the old password directly from the
session. Any suggestion would be very helpful. Thankyou..!!
Use the same method or make a similar one to the method you use for logging in...
Edit: Appended "or LDAP" to question title to indicate that I would be fine to have a solution which made it possible for me to authenticate with LDAP credentials.
My Question: How do I authenticate a BusinessObjects session using credentials with Active Directory?
Example: I have (I think) an example from SAP on how to do this in .NET but I can't seem to find a similar solution for Java. (See this pdf and search for "Modify the .NET Web Application to enable Kerberos").
Currently: I have a solution to authenticate using an Enterprise Account:
/**
* Logs into BusinessObjects. Sets the reportEngine and biPlatform
*/
public void loginToBusinessObjects() throws AxisFault, MalformedURLException, Exception {
LogHelper.println("Server connection: " + boServer);
URL boConURL = new URL(boServer);//set connection URL
connection = new com.businessobjects.dsws.Connection(boConURL);
boSession = new Session(connection); //setup new session
EnterpriseCredential credential = EnterpriseCredential.Factory.newInstance();
credential.setLogin(boUsername);
credential.setPassword(boPassword);
LogHelper.println(boUsername + ": ##password##");
boSession.login(credential); //login to server
...
}
The code above works great.
Now: I want to be able allow users to give their Active Directory credentials and authenticate using those. I can't seem to find a way to do this however. Documentation on the code above can be found in that same pdf searching for "Logging in to a server."
Note: I could be going about this all wrong. My organization uses the same credentials for Active Directory and LDAP Authentication. If there's a way to do this using LDAP that may be sufficient. Thanks.
The answer assumes you have set up the Active Directory and/or LDAP authentication for users and the user(s) have an alias to that authentication method. This should be verifiable by logins into InfoView.
You should be able to do it by using credential.setAuthType(authType).
Where authType is
"secEnterprise" default value
"secLDAP"
"secWinAD"
Seems and makes sense that by default the AuthType is set to secEnterprise.
Note: I'm still on R3 which has a slightly different authentication mechanism and I have not specifically tried this solution.
Important Edit: The documentation (which is awful for BusinessObjects and anyone reading this probably already knows that) says that for active directory you use "secAD". However, in my testing I was able to successfully authenticate using "secWinAD" which does not appear anywhere in their documentation at all :-/ (that I could find).
