Just recently released a huge db on a customers site.. all xpages and they use it mainly in Notes 9 Client.. In favour of performance, i tried the option "Run server-based XPages applications directly on a Domino server" .. which turned out to be a pandoras box:

• Users have to have an account -> rather easy with policies, if there weren't a bug which crashes the notes client (assigned to IBM and SPR created).. workaround if the user enters the credentials in the account directly.. thats not such a problem
• Users have multiple PCs: Unfortunately, the Account documents are not replicated like the Person documents, so the Users have to manage their accounts on all their machines..
• Password Changes: If the Users are changing the Internet Password, they have also to change the password in all their XPages account documents.. nobody want's to do that, helpdesk will go crazy!

I'm sure i'm doing something wrong and i'm sure thats not "works as designed" .. so whats the better approach?

regards,
