Create two hosts with the same PSK and different keys. This will produce error like:
Key can be created like:
Add auto-registration rule with the same PSK, on the agent side get:
Add another host with the same PSK and Connect to: PSK, Connect from: NoEnc, PSK.
Restart Agent multiple time or wait for autoregistration process.
Get hosts registered. Next restart will fail with the already mentioned message.
Second inconsistency: enable both autoregistration with no enc and PSK enc;
Host will be registered even if PSK identity has duplicates. But host will be added with PSK only encryption.
Some installations has another error on the same issue with duplicate PSK identity:
It look likes PSK keys are used in a round-robin way, before auto-registration denied.
Also message: "connection used PSK which is not configured for auto-registration" - has no useful meaning, description - should be documented in a known issues.
