Transparent SSO isn't working and the Error log contains the following error:
Multiple load balanced IdPs with a realm that has it's validation and decryption keys set to AutoGenerate Isolate Apps.
What that means is each node is independently setting their own random encryption keys (for cookies) at runtime.
That means that any PreAuth cookies that it tries to read could be encrypted with a different key from one of the other nodes.
To prevent this happening, generate new fixed keys and copy/paste them to the other nodes for the respective realm. Then all the nodes will be able to read each others cookies.
