Dear all,
I experience a strange phenomenon on my SP2010 installation (SQL 2008 on a separate server, one Frontend, standard sync with AD-2003 Domain controller) propably since last Friday.
When opening the start page of the SP environment, the user sees a different user (not his own login) in the upper right corner - and also the access rights are as for this user. Example: User Chris opens sharepoint and sees himself as Caroline, and seems to have access to all the elements for which Caroline has access rights. Whenever he selects a sub-site or opens an element, two things can happen:
A) He becomes "himself"
B) He switches to another user, in the example this could be user Tom.
I also experienced a "user change" on the starting page without(!) reloading the page or any navigation.
Non of the LogFiles (Event Logs, SP) on SP or SQL show any suspicious entries, also the database integrity is ok.
We installed Cumulative SP Updates last Weekend (since February), but we are suspicious that the error was there before. Anybody with similar experience around?
Thanks,
Christof
