So far I’ve found the following bugs (or things that can be improved in later releases):

– Administration breadcrumb is all over the place. It’s really-really hard to navigate to where I was before without going back to the main Central Admin screen. Especially when I was in a particular Service Application page, the breadcrumb didn’t trail correctly. It only displayed Central Administration > Current Page.

– User Profile Sync page didn’t display information correctly. I have started my sync process but the page keeps saying: “Idle – Completed in 0h 0m 0s”. And even worse I still saw the link saying “Start Profile Synchronization”. As a user I thought there must be something wrong with the process. I clicked on the link again and now it gave me popup error message saying User Profile sync is still running bla bla bla.

– As mentioned on various blogs, when you first started the User Profile Sync service it keeps saying “Starting” until you visit the Monitoring – Job Status page and waited until the process is finished, that’s when Service page will say “Started”. See http://blogs.msdn.com/opal/archive/2009/11/19/user-profile-sync-setup-in-sharepoint-server-2010-beta.aspx.

– It couldn’t crawl AD unless I’m using the service account to login to the farm. I was trying to login using the account that I used to install Sharepoint (SEGORO\sp_admin) – which I assumed it would be the “God” mode account – which it was in MOSS 2007 – and it still failed. I had to use SEGORO\sp_farm instead.

– It would be handy if stsadm (and other Sharepoint-related commands) command can be added to Environment Variables automatically upon installing Sharepoint since we (the SP developers) will be using these so much.

That’s what I’ve found so far, I’ll keep posting the bugs I found on SP 2010 Beta.
