When Post Auth Rule is set but evaluation result is false, WNA authentication fails.
Now the problem is that this has broken Kerberos authentication for users. OAM is complaining about "KrbException: Request is a replay (34)".

However, the same use case works for LDAPScheme for example.

Expected result: Resource should be accessible for WNA use case after Kerberos Authentication with NO error, that even though the Post AuthN rule condition is evaluating to false.

The issue can be reproduced at will with the following steps:

Testcase instructions (or location of instructions):
 1. Set up Post authentication Scheme with Kerberos Scheme.
 2. Set condition to evaluate to false.
 3. Access the resource.
