A single proxy server fails

The effect is the same as a target server being disconnected. Users may see that requested operations, such as password changes, have not happened yet. You can run system operation reports; for example to see which password have been expired and not changed recently. You can also review logs to detect failed password reset attempts in the form of connectors errors.

A recommended way to detect this condition and related problems is to configure events to trigger email or update tickets in the event of a failed operation.

Resolution

The main Bravura Security Fabric servers will be unable to scramble passwords on devices supported by that proxy server. The Bravura Security Fabric server is unable to connect to any device that requires that proxy server. Bravura Security Fabric will be unable to carry out operations involving a target system, including listing information, or updating data such as passwords on a machine.

Users can still log into Bravura Security Fabric , assuming they are not authenticating against a target through the damaged proxy. They can access their profiles and carry out tasks that do not require a connection to affected target systems.

A problem occurs on a single Bravura Security Fabric proxy server. This may be for a variety of reasons, including:

  • Hardware problem, such as a disk crash.

  • Operating system problem, such as a bug, or full disk.

  • Application problem, such as a bug or misconfiguration.

None, unless an extremely unlikely race condition takes place:

  • A password update is initiated on a target system.

  • The password update succeeds.

  • Before the "success" result code is returned to the Bravura Security Fabric server, the proxy server in question fails.

  • As a result, the Bravura Security Fabric server "thinks" the password change failed and records a failure, rather than the new password.

Repair/replace the failed proxy server as soon as possible. Bravura Security Fabric proxy servers are essentially stateless so a fresh installation on a new physical server or virtual machine is all that is required.
