Angela Schreiber commented on OAK-8763:

[~baedke], ah right... i got confused, which of the 2 issues you were posting to because the
discussions kept getting mixed. and yes, i mean the principals from the read-only subject.

> LoginContextProviderImpl#getLoginContext(...) extracts the most recent subject from the
AccessControlContext and then uses it for either a PreAuthContext or a JaasLoginContext. This
is wrong, because there is no reason to assume that such a subject has anything to do with
Oak. It particularly hurts when it's readonly, because JAAS will then silently fail to add
principals and credentials.
> We would need a way to identify pre-authenticated subjects and subjects that are not
pre-authenticated should not be used to create a JaasLoginContext.
