ACTUAL BEHAVIOR
After configuring single sign-on (SSO) for Microsoft clients (WNA/Kerberos) with WebCenter Portal Domain, the users are not authenticated.
The following behavior is observed:

- WNA / Kerberos authentication works with WebCenter Content.
- WNA / Kerberos authentication only fails with WebCenter Portal.
- User might get the following message:
Sorry, you do not have access.
If you have an account, please login first. - Users are logged in after providing user credentials which is unexpected.
EXPECTED BEHAVIOR
Expect the user to be authenticated without providing user credentials.
STEPS
The issue can be reproduced at will with the following steps:
- Configure WebCenter Portal with Active Directory as an external LDAP.
