It is possible but look like I need to create a detailed video for that. You can create a class like CustomAuthoritiesPopulator implements AuthoritiesPopulator { } then implement the override function. After that in custom security config you can inject the CustomAuthoritiesPopulator class and add ldapAuthoritiesPopulator.
You are most welcome. So in your case you will pass full dn. like cn=abc,ou=user along with password and you need to login. Here dn can be different for different user. Please correct me if I am wrong.
Hi, if you watched all the video then definitely you got some idea😄. Anyways try with basics like create login application then use authentication,next do Authorization. After that learn about permission then add do ldaps and bla bla . You need to start first, automatically you will get a better idea😊
thank you so much its so helpful I'm working on creating an application to manage Active Directory but I'm encountering many issues. So, I'm asking if you can help me
You are most welcome. You can follow below steps: 1.Configure LDAP Authentication: -Set up LDAP authentication in your Spring Security configuration. 2.Generate JWT upon Successful Authentication: -Create a JWT upon successful LDAP authentication. 3.Authorize Requests Using JWT: -Use the JWT to authorize requests from the frontend. like code sample below: in login API: do Authentication first, then get user details and create JWT token Authentication authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password)); SecurityContextHolder.getContext().setAuthentication(authentication); UserDetails userDetails = (UserDetails) authentication.getPrincipal(); return jwtUtil.generateToken(userDetails.getUsername());
Thank you!. Your video is very helpful! This approach secures all routes/endpoints in the app as I understand it, but what I need is just a login endpoint that authenticates users to the LDAP server and returns a response to the front-end app. Therefore I need to enable access to some endpoints without authentication. How can I implement this? I would be very happy about your answer!
Glad it helped! yes we can do. You can go with verifyPassword approach. Currently I have started Spring Boot LDAP Tutorial series.in that I will surely show that. But for now you can do one thing. Try to pass uid/cn and password to controller. Like below: boolean passwordMatch = ldapService.verifyUserPassword(cn, enteredPassword); You can create a Ldap Service class where you can do all LDAP Activity( I am going to upload a video today like how to add ldap user,you can refer). In LDap Service try to get user By ldapUser by UID or CN(Whatever you want). LdapUser ldapUser = getUserByCn(cn); once you got user then try to check password. ldapUser .getPassword.equals(enteredPassword); NOTE: You might face issue during password verification like password encrypted. Check carefully
@@TalentedDeveloper thank you for your answer! i checked your new video.. i am not sure if it will work, since the ldap server that i use to authenticate will return only "true/false" kind of answer. i can not retrive the user recored. Additionally, i dont want to return a login form to the user, because i want to do that in the spa frontend app.. i just need an endpoint to tell me if the credentials are correct or not, so that i can return a token to the spa later.
you no need to show the login screen to ui. You can allow your endpoint url from spring security (check security config) and you can play with code. Else I am having the best solution, which will return true and false. please check this ruclips.net/video/uZ_q-_diVpM/видео.html
Hi very much helpful video ,but I am facing a issue that when we are running LDAP on IP but whenever I am calling from spring boot project it is throwing 401 unauthorised exception. But if I use that same credentials and connect to that LDAP ,it successfully connects from Apache directory studio . Please provide me some inputs for the issue. Thanks
Thank you. Can you please check your spring security configuration. If possible please check if the ldap connection is connecting successfully or not. If connection is fine then please check DN, it has to match with ldap user dn.
To ascertain the successful establishment of an LDAP connection in a Spring Boot application, a straightforward approach involves executing a basic operation, such as searching for a user or retrieving information from the LDAP server. The absence of any exceptions during the operation signifies a successful connection. Below is a sample code for creating a function in the LdapService class(github.com/talenteddeveloper/Spring-Boot-LDAP-Overview/blob/main/src/main/java/com/learn/springBootLdapOverview/service/LdapService.java). public boolean isLdapConnectionValid() { try { // Adjust the DN as per your connection details ldapTemplate.search("ou=people,dc=example,dc=com", "(objectclass=inetOrgPerson)", null); return true; } catch (Exception e) { // Log the exception or handle it as necessary return false; } } Make sure to customize the DN according to your specific connection. If the function returns true, the connection is established successfully; otherwise, ensure that the credentials are correct.
hi thanks for making this video but i am unable to start the server .i have chnaged my jdk in config file like -vm and my java.exe location but it still is not working . i am using spring boot 3.2 with jdk 17.please help .
Hello, thank you for your video, it was very well done. Currently, I am encountering some problems regarding the operation of Apache DS and Apache Directory Studio. When I try to modify the name of dc=example,dc=com through 'Open Configuration', for example, changing it to dc=myldap,dc=com, I am unable to save the changes. The following error occurs: 'Save Configuration' has encountered a problem. Unable to save configuration. - Unable to convert the configuration bean to LDIF entries. I wonder if you have ever encountered such a problem. This issue prevents me from importing .LDIF files. Thank you very much!"
Hi Kevin, Thanks for your valuable feedback. I never tried like that. But I remember once I updated dc=example,dc=com with my custom name. And I did ldap operation. But never tried to import the ldif file. I will check from my end. When you try to import,at that time try to see the object class structure and make sure it will match your Apache DS.
Hi, Please check the steps, I feel something you miss. If possible please check your error in the console. The maximum probability is that your configuration can be wrong.
Thank you for sharing the video. It was very helpful.
Most welcome
Thanks for the details. It's helpful.
Thanks for your valuable feedback
OMG, that's brilliant. Thanks man!
Thanks 👍🏻😊
excellent tutorial! much better than official spring guide which only use internal User Data file
Thank you so much for your valuable feedback
Thanks! This helps me set the authentication function in my Spring project.
Most welcome and Thanks
Hi, thank you for this wonderful tutorial. I have a scenario where I have to use LDAP AuthoritiesPopulator. How to go about it?
It is possible but look like I need to create a detailed video for that.
You can create a class like
CustomAuthoritiesPopulator implements AuthoritiesPopulator { } then implement the override function.
After that in custom security config you can inject the CustomAuthoritiesPopulator class and add ldapAuthoritiesPopulator.
Very good content!
Thanks!
Thank you. It's sure is helpful. Can you show how to retrieve user details after user logs in with LdapAuthoritiesPopulator?
you can check this ruclips.net/video/c7oHdzmOfZo/видео.html.
Its a nice video..
Please make a video on how to configure LDAP over TLS
Thanks and Sure I will try
Thank you so much and also could you please show us to login using only cn as we have different ou's for different users
You are most welcome.
So in your case you will pass full dn.
like cn=abc,ou=user
along with password and you need to login.
Here dn can be different for different user.
Please correct me if I am wrong.
Hi, I watched all of your videos related to LDAP. I am new to LDAP. Can you suggest me, how to start learning LDAP to understand better.
Hi,

Thanks, now I just have a question, how can i create a Json Web Token using LDAP to authorize frontend request.
You are most welcome.
You can follow below steps:
1.Configure LDAP Authentication:
-Set up LDAP authentication in your Spring Security configuration.
2.Generate JWT upon Successful Authentication:
-Create a JWT upon successful LDAP authentication.
3.Authorize Requests Using JWT:
-Use the JWT to authorize requests from the frontend.
like code sample below:
in login API:
do Authentication first, then get user details and create JWT token
Authentication authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));
SecurityContextHolder.getContext().setAuthentication(authentication);
UserDetails userDetails = (UserDetails) authentication.getPrincipal();
return jwtUtil.generateToken(userDetails.getUsername());

Thanks for the video. Is it possible to have two-factor authentication with LDAP?
Yes, it is possible to implement two-factor authentication (2FA) with LDAP in a Spring Boot application.
I will make video very soon
Hi ,
Nice tutorial.
Now I want to implement ldap caching with spring boot .
Any suggestions
Hi, Thanks.
I also need to check
Did you check above
I am not getting proper solution
sorry I didn't check till now
Thankyou….. it is so helpful😊
Always welcome
hi thanks for making this video but i am unable to start the server .i have chnaged my jdk in config file like -vm and my java.exe location but it still is not working . i am using spring boot 3.2 with jdk 17.please help .
try to set java home as jdk11 and in eclipse use java 17 jdk.
Try this once, I hope it will work
it worked .thanks man@@TalentedDeveloper
Thank you so much :)
You are most welcome
is it possible to validate without LDAP. I mean logon with windows logon ?
May be possible, I never tried
Hello, thank you for your video, it was very well done.
Currently, I am encountering some problems regarding the operation of Apache DS and Apache Directory Studio.
When I try to modify the name of dc=example,dc=com through 'Open Configuration', for example, changing it to dc=myldap,dc=com, I am unable to save the changes.
The following error occurs: 'Save Configuration' has encountered a problem. Unable to save configuration. - Unable to convert the configuration bean to LDIF entries.
I wonder if you have ever encountered such a problem. This issue prevents me from importing .LDIF files. Thank you very much!"
Hi Kevin,
Thanks for your valuable feedback.

But I remember once I updated dc=example,dc=com with my custom name. And I did ldap operation. But never tried to import the ldif file. I will check from my end.
When you try to import,at that time try to see the object class structure and make sure it will match your Apache DS.
I am getting connection refused when tried to login
are you trying to connect to localhost or other ip?
can it is same work for Active Directory user and computer
I think yes
Thanks a lot
Awesome
Thank you so much
This does not work for me
Hi,
Please check the steps, I feel something you miss.
If possible please check your error in the console.
The maximum probability is that your configuration can be wrong.
