Problem

Credential mismatch after changing NSX Advanced Load Balancer controller password.

Cause

If you change controller password for admin user from outside of NSX-T from the Avi Vantage Platform UI, the new password does not refresh in NSX-T. Any change of password outside of NSX-T is not reflected in NSX Manager. NSX Manager does not reflect the state of the cluster.

Solution

  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. If you changed the password outside of NSX-T, run the following API to change password.
    PUT https://<NSX-Manager-IPaddress>/api/v1/alb/controller-nodes/deployments/<node_id> 
    {
"form_factor": "SMALL",
"user_settings": {
"admin_password": "Tilak@123456"
},
"deployment_config": {
"vc_id": "755bd5cb-3700-456c-b74e-25f5140f4a50",
"compute_id": "domain-c201",
"host_id": null,
"storage_id": "datastore-206",
"management_network_id": "network-207",
"hostname": "controller-AA",
"placement_type": "AlbControllerVsphereClusterNodeVmDeploymentConfig",
"disk_provisioning": "THIN",
"dns_servers": [
"8.8.8.8"
]
}
}
  3. If you changed the password from NSX-T, run the following API to change password, DNS and NTP servers in NSX-T and on the NSX Advanced Load Balancer controller.

    PUT https://<NSX-Manager-IPaddress>/api/v1/alb/controller-nodes/deployments/<node-ID>?running_config=true
