Key Rotation Issue with Multiple Gluu Servers

I am experiencing an issue with key rotation across our two Gluu servers. Here’s a summary of the problem: When the key rotation timer executes on one Gluu server, new public keys are successfully generated and stored in LDAP. Due to LDAP replication, these updated public keys are then synchronized to the second Gluu server as expected. However, I am concerned about the /etc/certs/ directory, particularly the pkcs12 keystore file, which contains the corresponding private keys. I want to ensure that both servers have the correct private key file synchronized. Could you clarify the following: Does Gluu automatically handle synchronization of the pkcs12 keystore file across multiple servers, or do I need to configure multi-master replication in the cluster manager to synchronize the /etc/certs/ directory between servers?
Gluu 4.5 Ubuntu 22.04

Hi Mursel, How you built this cluster? Is it VM based or Cloud Native. if VM based, which doc you followed?

Hi Mohib We have two cluster managers for the same servers: one is set up on my local PC and the other on a Windows server. I did not follow any specific online documentation for this setup, as we had a backup configuration for the cluster manager in place.

I am not precisely sure how "two" cluster manager might work together BUT I am sharing what a standard procedure might look like... Cluster-Manager has a feature named [Key Rotation](https://gluu.org/docs/cm/4.4/deploy/#key-rotation) which you should use if you use VM based cluster with Cluster Manager. But if you use Cluster Manager's "Key Rotation" feature, you should keep oxAuth's key regeneration feature off. Screenshot attached.

Okay I understand, When i go to the key rotation section of cluster manager, I get an error "Key generator .../keygen.jar was not found. Key rotation will not work unless the instructions are followed https://gluu.org/docs/cm/installation/#add-key-generator ". When navigating to the URL and following the instructions to download this jar. I am greeted with a login page to download. or when making the request in my server i get "Unauthorized". Why do we need these credentials and where can I find it?

Okay thanks, I will send an email for the access. I also found this link "https://gluu.org/docs/gluu-server/4.0/operation/replace-expired-jks-scim/#manually-generate-and-apply-key" to manually replace the keys, but I am missing the "org.gluu.oxauth.util.KeyGenerator" do you know where I can find or download this?

That should be inside `/opt/dist/gluu/oxauth-client-jar-with-dependencies.jar` You can try command like... `/opt/jre/bin/java -Dlog4j.defaultInitOverride=true -cp /opt/dist/gluu/oxauth-client-jar-with-dependencies.jar org.gluu.oxauth.util.KeyGenerator -keystore ......`
