Original comment by @tvernum:
The change to introduce the _xpack_security system user (LINK REDACTED) seems to have had a couple of different BWC issues that weren't picked up by our tests.
-
If a new node, tried to load security data from an old node, it would try to use the new user and fail because the old node didn't recognise the
_xpack_securitysystem user. (Fixed in LINK REDACTED) LINK REDACTED -
If an old node tried to load security data from a new node, it would try to use the old user and fail because the older user no longer has permission to read security data. (Also fixed in LINK REDACTED) LINK REDACTED
It would be helpful to have some security tests that run with the sorts of more complex cluster setups (dedicated coordinating nodes, dedicated master nodes) that pull out these issues.
