When configuring WNA with SSO and trying to generate a keytab file for the SSO Server by running ktpass on the Active Directory/KDC Server, ktpass produces unexpected warnings and if prompts are accepted will reset the password in Active Directory.
Targeting domain controller: adcore.ad.oracle.com Using legacy password setting method WARNING: Account SSOSERVER$ is not a normal user account (uacFlags =0x1000).
Do you really want to delete any previous servicePrincipalName values on SSOSERVER$ [y/n]? y Successfully mapped HTTP/ssoserver.uk.oracle.com to SSOSERVER$ WARNING: Resetting SSOSERVER$'s password may cause authentication problems if SSOSERVER$ is being used as a server.
Reset SSOSERVER$'s password [y/n]?
If 'y' is entered connections can no longer be made to Active Directory as this user.
kinit is failing for SSO Server servicePrincipalName with error 'Client not found in Kerberos database'.

However the 'ssoserver' user can be viewed in Active Directory Users and Computers with servicePrincipalName=HTTP/ssoserver.uk.oracle.com, so it does exist in the Kerberos database.
