Keycloak federation with LDAP fails to make the connection : Error! Error when trying to connect to LDAP. See server.log for details

I am trying to create a federated authentication using the Keycloak and following the steps mentioned here: Setup User Federation with Keycloak

I have been using the port 10389 instead of 389 mentioned in the document. Everything seems to be working fine until the step where I am making the connection from Keycloak to LDAP.

When I provide the Connection URL as ldap://localhost:10389 and click on the Test Connection then I get the error:

Error! Error when trying to connect to LDAP. See server.log for details

I am not sure what's wrong because when I check in the Apache Directory Studio there everything seems to be working fine for me and I am able to get all the users list etc. I am not sure why I am unable to make the connection from Keycloak to LDAP.

I tried the following things but nothing worked for me:

  1. ldap://localhost:10389
  2. localhost:10389
  3. ldap://127.0.0.1:10389
  4. ldap://localhost:389
  5. Stopped the docker in the dashboard and started again.

After trying a lot I found the solution. Posting the answer as it can be useful to someone else in the future.

I was using the localhost and 127.0.0.1 which was not working. Finally, I checked the IP Address of my system using the terminal (for mac ipconfig) and tried that and it worked:

ldap://192.168.1.12:10389
