In my configuration i have:

• Domain controller
• Oracle database server (Windows Server 2016 Standard)
• Client (Windows 10 Pro)

Kerberos authentication is configured. The ticket cache is stored in a file (system variable KRB5CCNAME is set on client).

The question is: is it possible to store a ticket cache not in file?

I founded information about the OSMSFT/ MSLSA option (storing a ticket cache in Windows memory). But as I understand it, it isn’t possible with active Credential Guard in Windows 10 and later versions of Windows.

Are there other ways to store ticket cache? If not, please share links to Windows/Oracle documentation that can prove this (proof links is needed for discussion with the customer).
